Wind tunnel experimental research on the effect of col topography on wind environment

Liu Hui

Sains Malaysiana, 2016;45:99-107.

Investigation of meteorological disasters caused by small-scale topography shows that flashover due to wind age yaw occurred quite often where col topography existed. Considering that the distribution pattern of wind profile at different locations of a col topography is not clear, this paper, with wind tunnel tests, studied the influenced of such topographic features of a col as hill slope and valley mouth width on the wind profile at different locations. The results of wind tunnel tests indicated that over-hill wind has a stronger effect on wind velocity correction coefficient than does valley wind, that compared to flat terrain wind velocity, the maximum speed-up amplitude of wind velocity at valley throat and hill summit reach 33 and 53%, respectively, apparently higher than 10% specified in Codes, that wind velocity at valley throat increases with the increase of hill slope and decreases with the increase of valley mouth width, that wind velocity in the valley basically does not go up when the slope of one hill side is smaller than 0.1 and that wind velocity at the same non-dimensional height of a 3D hill summit increases with the increase of hill height.

Vulnerability of Vietnam to typhoons: A spatial assessment based on hazards, exposure and adaptive capacity

Nguyen KA, Liou YA, Terry JP

Sci Total Environ, 2019 Sep 10;682:31-46.
PMID: 31121354 DOI: 10.1016/j.scitotenv.2019.04.069

Typhoons have devastating impacts across many Asian countries. Vietnam is presently one of the most disaster-prone nations. Typhoons regularly disrupt human lives and livelihoods in various ways and cause significant damage. Making efficient policy decisions to minimize the vulnerability of affected communities is crucial. This requires a deep understanding of the factors that make a society vulnerable to extreme events and natural disasters. An appropriate approach is integrating the three dimensions of hazard, exposure and sensitivity, and community adaptive capacity. However, the vulnerability and adaptive capacity response to typhoons within Vietnam is poorly investigated. Here, we develop a conceptual framework that incorporates 21 indicators to identify vulnerability and adaptive capacity (VAC) using geospatial techniques at regional scales, applied over Vietnam. We find large spatial differences in VAC and are able to identify the top-priority regions that need to enhance their adaptation to typhoons. The Southern Coastal area, South East and Red River Delta demonstrate high and very high vulnerability because of their physical features and the intensity of typhoons that frequently cross these parts of Vietnam. The lower Mekong Delta and Northern Coastal areas are vulnerable to typhoon-driven flood threats, in particular where compounded by sea-level rise. Our framework successfully identified the spatial distribution and different levels of VAC within acceptable limits of uncertainty. It can therefore serve as a template to tackle national issues in disaster risk reduction in Vietnam and assist in the development of suitable mitigation strategies to achieve sustainable outcomes.

Visualizing disaster attitudes resulting from terrorist activities

Khalid HM, Helander MG, Hood NA

Appl Ergon, 2013 Sep;44(5):671-9.
PMID: 22944486 DOI: 10.1016/j.apergo.2012.06.005

The purpose of this study was to analyze people's attitudes to disasters by investigating how people feel, behave and think during disasters. We focused on disasters induced by humans, such as terrorist attacks. Two types of textual information were collected - from Internet blogs and from research papers. The analysis enabled forecasting of attitudes for the design of proactive disaster advisory scheme. Text was analyzed using a text mining tool, Leximancer. The outcome of this analysis revealed core themes and concepts in the text concerning people's attitudes. The themes and concepts were sorted into three broad categories: Affect, Behaviour, and Cognition (ABC), and the data was visualized in semantic maps. The maps reveal several knowledge pathways of ABC for developing attitudinal ontologies, which describe the relations between affect, behaviour and cognition, and the sequence in which they develop. Clearly, terrorist attacks induced trauma and people became highly vulnerable.

Fulltext Unheard voices : womens’ inner experiences during the Johore flood

Zabedah, B., Badrul Hisham, A.S.

Malaysian Journal of Community Health, 2009;15(3):98-103.

Introduction : Human displacement during disaster would cause women and their dependent children to be particularly vulnerable. Yet, women failed to make their voices heard. Thus their needs, priorities and perceptions would not be identified which in turn could hinder an effective emergency response and a full recovery process.
Objective : This paper provides a general overview of problems and issues experienced by women and their dependent children during the Johore flood disaster. With this information, relevant agencies shall focus, among other considerations, on the special needs of women and children in planning and carrying out emergency responses in the future.
Methodology : This paper was written based on data and information obtained from the Johore Flood Disaster Report and observations made by the health teams on the flood victims throughout the flood period.
Findings and Discussions : Pregnant mothers with 36 weeks of gestation or more were evacuated from their homes to the health centres or hospitals when the Johore flood disaster struck. Regular maternal and child health (MCH) services were conducted at the flood relief centres. Despite the efforts by health care providers, we observed women facing some unique issues and problems. These include: 1) Effects of loss of security and protection; 2) Disruption of social relations and privacy; 3) Inadequate supply of basic items and; and 4) Economic disruption. Recommendations for future relief work are: i) Predisaster planning for emergency response must engage and involve women representatives. Women must also be recruited as emergency and relief workers; ii) Assessment of predetermined capacity of identified relief centres with gender consideration for evacuees must be done; iii) All relief centres shall have physical partition between families. Breast feeding room with access to clean water should also be provided; iv) Gender, cultural and religious sensitivity with regards to social protection and relations shall be observed at all times; v) Women should engage and be made occupied with suitable activities to encourage healthy social interaction thus avoiding feelings of boredom and helplessness; vi) Basic personal items for women and adolescent girls, such as sanitary towel and undergarments, and places to wash and hang them in privacy must be provided; vii) Elderly women may have to temporarily stay at unaffected relatives’ or old folk homes throughout the disaster period, and; viii) No smoking policy shall be enforced at all times in flood relief centres.
Conclusion : Women and their dependent children have been recognised as one of the vulnerable groups during disasters. Thus, women shall be empowered as partners in formulating any emergency response plan so that together they would be able to complement all disaster mitigation, relief and recovery efforts in amore effective manner.

Underwater DVI: Simple fingerprint technique for positive identification

Khoo LS, Hasmi AH, Mahmood MS, Vanezis P

Forensic Sci Int, 2016 Sep;266:e4-e9.
PMID: 27567043 DOI: 10.1016/j.forsciint.2016.08.019

An underwater disaster can be declared when a maritime accident occurred or when an aircraft is plunged into water area, be it ocean, sea or river. Nevertheless, handling of human remains in an underwater recovery operation is often a difficult and demanding task as working conditions may be challenging with poor to no visibility, location of remains at considerable depths and associated hazards from surrounding water. A case of the recent helicopter crash, into a famous river in Sarawak, domiciled by huge crocodiles, is discussed in this paper. Search and recovery team as well as the combat divers from the Special Elite Troop Commando, known as VAT 69, were deployed to the scene to perform the underwater recovery to search for all the victims on board involving five Malaysians with a pilot of Philippines nationality. This paper highlights the limitations and challenges faced during the underwater search and recovery. All the bodies recovered were in moderate decomposition stage with crushed injuries and mutilated face and body. A simple and conventional fingerprint technique were used to record the fingerprint. The prints impressions were later photographed using a smartphone and transferred back to the RMP headquarters in Kuala Lumpur for fingerprint match by using WhatsApp Messenger, a phone application. All the first five victims were identified within an average of 10min. The last victim recovered was the pilot. For foreign nationals, the Immigration Department of Malaysia will record the prints of both index fingers only. The lifting of the fingerprint of the last victim was the most challenging in which only one index finger left that can be used for comparison. A few techniques were attempted using the black printer's ink, glass and tape techniques for the last victim. Subsequently, images of the prints impression were taken using the same smartphone with additional macro lens attached to it to enhance the resolution. The images were transferred to the RMP headquarters through WhatsApp Messenger. The prints were confirmed to be the pilot 20min later.

Fulltext Understanding human vulnerability to climate change: A global perspective on index validation for adaptation planning

Birkmann J, Jamshed A, McMillan JM, Feldmeyer D, Totin E, Solecki W, et al.

Sci Total Environ, 2022 Jan 10;803:150065.
PMID: 34525713 DOI: 10.1016/j.scitotenv.2021.150065

Climate change is a severe global threat. Research on climate change and vulnerability to natural hazards has made significant progress over the last decades. Most of the research has been devoted to improving the quality of climate information and hazard data, including exposure to specific phenomena, such as flooding or sea-level rise. Less attention has been given to the assessment of vulnerability and embedded social, economic and historical conditions that foster vulnerability of societies. A number of global vulnerability assessments based on indicators have been developed over the past years. Yet an essential question remains how to validate those assessments at the global scale. This paper examines different options to validate global vulnerability assessments in terms of their internal and external validity, focusing on two global vulnerability indicator systems used in the WorldRiskIndex and the INFORM index. The paper reviews these global index systems as best practices and at the same time presents new analysis and global results that show linkages between the level of vulnerability and disaster outcomes. Both the review and new analysis support each other and help to communicate the validity and the uncertainty of vulnerability assessments. Next to statistical validation methods, we discuss the importance of the appropriate link between indicators, data and the indicandum. We found that mortality per hazard event from floods, drought and storms is 15 times higher for countries ranked as highly vulnerable compared to those classified as low vulnerable. These findings highlight the different starting points of countries in their move towards climate resilient development. Priority should be given not just to those regions that are likely to face more severe climate hazards in the future but also to those confronted with high vulnerability already.

Fulltext Tutorless board game as an alternative to tabletop exercise for disaster response training: perception of interaction engagement and behavioral intention

Chew KS, Wong SS, Tarazi ISB, Koh JW, Ridzuan NA'B, Wan Allam SASB

BMC Med Educ, 2023 Jun 12;23(1):432.
PMID: 37308907 DOI: 10.1186/s12909-023-04356-4

BACKGROUND: Although tabletop exercise is a commonly used method for disaster response training, it is labor-intensive, requires a tutor for facilitation and may not be ideal in a pandemic situation. Board game is a low-cost and portable alternative that can be utilized for this purpose. The purpose of this study was to compare the perception of interaction engagement and behavioral intention to use a newly developed board game with tabletop exercise for disaster training.
METHODS: Using the Mechanics-Dynamics-Aesthetics' (MDA) framework, a new, tutorless educational board game known as the Simulated Disaster Management And Response Triage training ("SMARTriage") was first developed for disaster response training. Subsequently, the perceptions of 113 final year medical students on the "SMARTriage" board game was compared with that of tabletop exercise using a crossover design.
RESULTS: Using Wilcoxon signed rank test, it was that found that tabletop exercise was generally rated significantly higher (with p

Tsunami run-up and inundation along the coast of Sabah and Sarawak, Malaysia due to a potential Brunei submarine mass failure

Tan WK, Teh SY, Koh HL

Environ Sci Pollut Res Int, 2017 Jul;24(19):15976-15994.
PMID: 28343360 DOI: 10.1007/s11356-017-8698-x

Submarine landslides, also known as submarine mass failures (SMFs), are major natural marine disasters that could critically damage coastal facilities such as nuclear power plants and oil and gas platforms. It is therefore essential to investigate submarine landslides for potential tsunami hazard assessment. Three-dimensional seismic data from offshore Brunei have revealed a giant seabed mass deposited by a previous SMF. The submarine mass extends over 120 km from the continental slope of the Baram Canyon at 200 m water depth to the deep basin floor of the Northwest Borneo Trough. A suite of in-house two-dimensional depth-averaged tsunami simulation model TUNA (Tsunami-tracking Utilities and Application) is developed to assess the vulnerability of coastal communities in Sabah and Sarawak subject to potential SMF tsunami. The submarine slide is modeled as a rigid body moving along a planar slope with the center of mass motion parallel to the planar slope and subject to external forces due to added mass, gravity, and dissipation. The nonlinear shallow water equations are utilized to simulate tsunami propagation from deepwater up to the shallow offshore areas. A wetting-drying algorithm is used when a tsunami wave reaches the shoreline to compute run up of tsunami along the shoreline. Run-up wave height and inundation maps are provided for seven densely populated locations in Sabah and Sarawak to highlight potential risks at each location, subject to two scenarios of slide slopes: 2° and 4°. The first wave may arrive at Kudat as early as 0.4 h after the SMF, giving local communities little time to evacuate. Over a small area, maximum inundated depths reaching 20.3 m at Kudat, 26.1 m at Kota Kinabalu, and 15.5 m at Miri are projected, while the maximum inundation distance of 4.86 km is expected at Miri due to its low-lying coast. In view of the vulnerability of some locations to the SMF tsunami, it is important to develop and implement community resilience program to reduce the potential damage that could be inflicted by SMF tsunamis.

MyJurnal

Past major flooding events for the state of Johore, Malaysia were recorded in 1926, 1967, 1968 and 1971. However, major meteorological phenomena that hit Johore on the 19th December 2006 (first wave) and the 12th January 2007 (second wave) were claimed to be the worst flood disaster in Johore in a 100 years. All eight districts were affected displacing 157,018 and 155,368 population during the first and the second wave event respectively. The Johore Health Department deployed substantial number of medical and health personnel to deal with the Johore flood crisis. Flood-related data were collected on daily basis between 19th December 2006 and 19th February 2007 using spreadsheet format from Flood Operational Rooms located at respective District Health Offices. Among flood victims 34,530 were found to have non-communicable diseases and 19,670 with communicable diseases. No major food- and water-borne disease outbreaks, such as cholera and typhoid, were reported in Johore. High success of public health measures was depending on the workforce of medical and health personnel on the ground. On the other hand, voluntary services offered by non-governmental organisations (NGOs), private sector and other volunteers should be well coordinated without compromising regulatory and ethical requirements. Crisis guidelines and plan of actions shall be updated so that they would be more relevant to the crises encountered on the ground.

Floods are considered an annual natural disaster in Kelantan. However, the record-setting flood of 2014 was a 'tsunami-like disaster'. Hospital Universiti Sains Malaysia was the only fully functioning hospital in the state and had to receive and manage cases from the hospitals and clinics throughout Kelantan. The experiences, challenges, and recommendations resulting from this disaster are highlighted from an emergency medicine perspective so that future disaster preparedness is truly a preparation. The history of how the health campus was constructed with the collaboration of Perunding Alam Bina and Perkins and Willis of Chicago is elaborated.

The importance of the medico-legal autopsy

Nadesan K

Malays J Pathol, 1997 Dec;19(2):105-9.
PMID: 10879249

All deaths due to unnatural causes and deaths that are believed to be due to natural causes but where the medical cause of death is not certain or known are subjected to an inquest. The objective of an inquest is to ascertain facts pertaining to the death. This is achieved by inquiry and at the conclusion of the inquest a verdict is arrived as to whether the death was due to a natural, accidental, suicidal or a homicidal cause. An inquest is not a trial. There is no complainant or defendant and at the conclusion of the inquest no judgment is passed. The inquest system exists in all parts of the world. In the English legal system, the person who conducts an inquest is called a Coroner. In Scotland, he is called a Procurator Fiscal. The United States of America use the Medical Examiner system. Most continental European countries and their former colonies follow the Code Napoleon. A postmortem examination may become necessary in certain deaths that come up for inquests. In these situations the authority which conducts the inquest will order a doctor to perform a postmortem examination (medico-legal autopsy). To perform a medico-legal autopsy, consent from the relatives of the deceased is not required. In an unexpected sudden death, only a doctor after a postmortem examination may be able to determine the cause of death. However, it is often wrongly assumed that the objective of a postmortem examination is only to ascertain the cause of death. This article deals with the purpose of the inquest and roles of the medico-legal autopsy.

Fulltext The impact of serving in disaster relief among volunteers in Malaysia

Chen HY, Ahmad CA, Abdullah KL

Chin J Traumatol, 2021 Jul;24(4):237-248.
PMID: 34112591 DOI: 10.1016/j.cjtee.2021.04.002

PURPOSE: Malaysian disaster relief volunteers have a long and proud history of participating in relief missions within and outside the country. Despite of a plethora of researches into the various areas of disaster relief, there has been a little scholarly activity looking into the experiences of the medical volunteers worldwide and even less research on the experiences of the relief volunteers in Malaysia. Therefore, the purpose of this study is to identify the effect of disaster relief works on volunteers in Malaysia.
METHODS: This is a non-experimental cross-sectional design study, which was conducted using survey questionnaire to examine the incidence of burnout, posttraumatic stress disorder (PTSD) symptoms and the quality of life (QOL) among the disaster relief volunteers. And the study also examined the socio-demographic variables of the participants. In addition, the association between the sociodemographic variable and the preferred coping strategies was also investigated through self-reporting checklist.
RESULTS: The findings of this study revealed that 90.9% volunteers (n = 312) experienced some levels of recurring stress throughout their lives, which led to burnout. Also, 96.8% (n = 332) of the participants were categorized as having at least some symptoms of PTSD. However, self-reporting QOL measurements indicated that the participants are, in general, satisfied with their lives. Significant associations between the incidence of burnout, incidence of PTSD and QOL were identified. Both positive coping measures and behavioral or avoidant coping measures were also identified. Furthermore, a number of socio-demographic factors were also seen to interact significantly with burnout, PTSD and QOL.
CONCLUSION: This study provides some insights into the psychological challenges of disaster relief volunteers in Malaysia, and this impact can last a long time after the volunteers return to their hometowns. Several recommendations including practice development, policy and research were discussed in the study.

The ecoclimatology of Danum, Sabah, in the context of the world's rainforest regions, with particular reference to dry periods and their impact

Walsh RP, Newbery DM

Philos Trans R Soc Lond B Biol Sci, 1999 Nov 29;354(1391):1869-83.
PMID: 11605629

Climatic records for Danum for 1985-1998, elsewhere in Sabah since 1879, and long monthly rainfall series from other rainforest locations are used to place the climate, and particularly the dry period climatology, of Danum into a world rainforest context. The magnitude frequency and seasonality of dry periods are shown to vary greatly within the world's rainforest zone. The climate of Danum, which is aseasonal but subject, as in 1997-1998, to occasional drought, is intermediate between less drought-prone north-western Borneo and the more drought-prone east coast. Changes through time in drought magnitude frequency in Sabah and rainforest locations elsewhere in South-East Asia and in the Neotropics are compared. The 1997-1998 ENSO-related drought event in Sabah is placed into a historical context. The effects of drought on tree growth and mortality in the tropics are assessed and a model relating intensity and frequency of drought disturbance to forest structure and composition is discussed.

Int Dent J, 1997 Feb;47(1):9-15.
PMID: 9448783

On 15 September 1995 a Malaysian Airlines (MAS) Fokker 50 plane plunged while descending and crashed, killing thirty-four passengers aboard. The dental disaster victim identification team comprising dental surgeons from the Dental faculty, University of Malaya; Ministry of Health, Sabah; and the Malaysian Defence Forces played an active role in the identification process. Most of the bodies were badly mutilated, disfigured and severely incinerated. Problems were encountered due to inadequate facilities and space at the mortuary. Difficulties were also encountered during the procurement and deciphering of information from dental records. This disaster has however created greater awareness amongst Malaysians of the important role of forensic odontology in mass disasters.

Fulltext The deadly ebola threat in the midst of an overwhelming dengue epidemic

Besari AM, Md Noor SS, Lee YY

Malays J Med Sci, 2014 Nov-Dec;21(6):9-13.
PMID: 25897277 MyJurnal

The recent death tolls and morbidities associated with two deadly viral haemorrhagic fevers (VHFs), i.e., Ebola and dengue, are simply shocking. By the end of August 2014, 65 672 people were afflicted with dengue fever (DF) in Malaysia, with 9505 from Kelantan, and there were 128 reported deaths. More astounding are the death tolls associated with Ebola: 3091 deaths from 6574 reported cases so far. It is not difficult to imagine the potential disaster if Ebola spreads beyond Africa. VHFs are characterised by an acute onset of fever, vascular disruption and a rapid progression to shock and death. The revised World Health Organization (WHO) 2012 classification (dengue with and without warning signs and severe dengue) is more clinically relevant and allows more streamlined admission. With good administrative support and public health and governmental efforts, the dengue epidemic in Malaysia is now more contained. However, there should be no laxity with the imminent lethal Ebola threat. Human-to-human transmission is an important mechanism for the spread of Ebola, and this calls for strict precautions regarding contact with any suspected cases. In contrast, the control and elimination of dengue would require successful control of the vectors and their breeding sites.

The association between social cohesion and community disaster resilience: A cross-sectional study

Ludin SM, Rohaizat M, Arbon P

Health Soc Care Community, 2019 05;27(3):621-631.
PMID: 30345603 DOI: 10.1111/hsc.12674

A cross-sectional study design was created, using the Index of Perceived Community Resilience (IPCR) and Buckner's Index of Cohesion (BIC) to survey 386 flood evacuees from six communities in Kelantan, Malaysia, in 2015. The respondents were mostly female (54.7%); lived in basic housing (95.6%); average income (55.9%); secondary level schooling (81.1%); not involved with community organisations (95.1%), volunteering activities (91.2%), or emergency teams (96.9%); inexperience with injury during flooding (94%); experienced the emergency disaster (61.6%); and their mean age was 49 years old. Overall, respondents scored a high level of community disaster resilience (CDR) (mean 3.9) and social cohesion (mean 3.79). Also, respondents' housing type, event of injury during disaster, volunteering in post-disaster activities, and emergency team participation were significantly associated with CDR (p = 0.001-0.002), organisational involvement (p = 0.016), and emergency disaster experience (p = 0.028) were significantly associated with social cohesion. The Pearson correlation coefficient results mostly showing a moderate, weak, and one with a strong relationship. There is a strong relationship between community participation (CDR) in events and BIC variables (r = 0.529, p = 0.001). Other analysis shows a moderate but significant relationship with BIC; is open to ideas (r = 0.332, p = 0.001); community has similar values/ideas (r = 0.421, p = 0.001); sense of pride (r = 0.389, p = 0.001); strong leadership (r = 0.339, p = 0.001); positive change (r = 0.484, p = 0.001); and able to handle problems (r = 0.454, p = 0.001). Overall, the results show that respondents had high levels of CDR and social cohesion, while the demographic characteristics show the impact of CDR and social cohesion. In conclusion, the data gives original insight into the level of association between social cohesion and disaster resilience, which could be used as a building block in sustainable disaster recovery. There is a need to explore this further on programmes designed to improve social cohesion across communities.

Fulltext The Malaysian Orthopaedic Association humanitarian mission to Indonesia and Sri Lanka

Sharaf I, Saw A, Hyzan Y, Sivananthan KS

Med J Malaysia, 2005 Jul;60 Suppl C:3-7.
PMID: 16381273

The tsunami which occurred off the west coast of North Sumatra on December 26, 2004 devastated the coastal areas of North Sumatra, South-West Thailand, South-East India and Sri Lanka killing more than a quarter of a million people. The destruction was enormous with many coastal villages destroyed. The other countries affected were Malaysia, Myanmar, Maldives, Bangladesh, Somalia, Kenya, Tanzania and the Seychelles. In January 2005, volunteers went in weekly rotation to Banda Aceh in collaboration with Global Peace Mission. These were Dr Hyzan Yusof, Dr Suryasmi Duski, Dr Sharaf Ibrahim, Dr Saw Aik, Dr Kamariah Nor and Dr Nor Azlin. In Banda Aceh, the surgical procedures that we could do were limited to external fixation of open fractures and debriding infected wounds at the Indonesian Red Crescent field hospital. In February, a team comprising Dato Dr K S Sivananthan, Dr T Kumar and Dr S Vasan spent a week in Sri Lanka. In Sri Lanka, Dato Sivananthan and his team were able to perform elective orthopaedic operations in Dr Poonambalam Memorial Hospital. We appealed for national and international aid and received support from local hospitals and the orthopaedic industry. International aid bound for Banda Aceh arrived in Kuala Lumpur from the Philippine Orthopaedic Association, the Chiba Children's Hospital in Japan and the Chinese Orthopaedic Association. The COA donated 1.5 tons of orthopaedic equipments. A special handing over ceremony from the COA to the Indonesian Orthopaedic Association was held in Putrajaya in March. Malaysia Airlines flew in the donated equipment to Kuala Lumpur while the onward flight to Aceh was provided by the Royal Malaysian Air Force. In April, Dr Saw Aik and Dr Yong Su Mei joined the Tsu-Chi International Medical Association for volunteer services on Batam Island, Indonesia. The MOA acknowledges the many individuals and organizations, both governmental and non-governmental, for their contributions in the humanitarian efforts.

The Fukushima nuclear crisis reemphasizes the need for improved risk communication and better use of social media

Ng KH, Lean ML

Health Phys, 2012 Sep;103(3):307-10.
PMID: 22850236 DOI: 10.1097/HP.0b013e318257cfcb

The potential of social media has expanded far beyond the initial function of social communication among a network of friends. It has become an increasingly important tool in risk communication to allow the dissemination of timely and accurate information to global citizens to make more informed choices regarding a particular crisis. The Fukushima nuclear crisis is an example where the potential of social media was not fully tapped. This caused undue stress and distrust of authorities. While the use of social media in this crisis could have altered significantly the level of trust in authorities and others, two additional points should be considered. One point is the use of plain language versus scientific language in order to reach a wider audience. The other is an urgent need to improve public information especially in the event of a nuclear emergency and to enhance educational efforts and action by improving radiological protection communication from regulatory bodies and international agencies. These are points that also play a large role in the use of social media.
