“…), our results show that only 10.4% of respondents evacuated immediately after perceiving the Natech threat, whereas 34.5% of them adopted other protective actions instead. This finding is consistent with an earlier study on households' immediate response to the 2009 American Samoa earthquake and tsunami (Lindell et al 2015). The authors also found that people did not leave immediately after the earthquake shaking but attempted to obtain additional information, packed an emergency kit, or protected property.…”

“…This is important to understand the role that risk perception plays in triggering multiple evacuations. Previous studies have shown that risk perception was strongly related to evacuation decisions (Baker 1991;Huang et al 2012;Lindell et al 2015). But emergency managers also need to know when household evacuation may begin (for example, evacuation based on a person's own judgment, after an evacuation order) in order to allocate emergency resources or start special protective plans.…”

“…The importance of studying the evacuation mode choice is also globally discussed. The concerns of the high demand for car use in tsunami evacuations and the corresponding jams have been raised both in the actual evacuation events [24][25][26] and the intended evacuation behaviours [27]. However, as clearly stated in [24], factors promoting car evacuation have not been clear.…”

“…The concerns of the high demand for car use in tsunami evacuations and the corresponding jams have been raised both in the actual evacuation events [24][25][26] and the intended evacuation behaviours [27]. However, as clearly stated in [24], factors promoting car evacuation have not been clear. Against the worldwide context of rapid urbanization and aging society, the investigation of factors that lead to appropriate/inappropriate evacuation mode choice is expected to provide essential information and implications for future better evacuations, not only in the study area, but also in worldwide tsunami prone areas.…”

Possible Factors Promoting Car Evacuation in the 2011 Tohoku Tsunami Revealed by Analysing a Large-Scale Questionnaire Survey in Kesennuma City

et al. 2017

Excessive car evacuation can cause severe traffic jams that can lead to large numbers of casualties during tsunami disasters. Investigating the possible factors that lead to unnecessary car evacuation can ensure smoother tsunami evacuations and mitigate casualty damages in future tsunami events. In this study, we quantitatively investigated the possible factors that promote car evacuation, including both necessary and unnecessary usages, by statistically analysing a large amount of data on actual tsunami evacuation behaviours surveyed in Kesennuma, where devastating damage occurred during the 2011 Tohoku Tsunami. A straightforward statistical analysis revealed a high percentage of car evacuations (approx. 50%); however, this fraction includes a high number of unnecessary usage events that were distinguished based on mode choice reasons. In addition, a binary logistic regression was conducted to quantitatively evaluate the effects of several factors and to identify the dominant factor that affected evacuation mode choice. The regression results suggested that the evacuation distance was the dominant factor for choosing car evacuation relative to other factors, such as age and sex. The cross-validation test of the regression model demonstrated that the considered factors were useful for decision making and the prediction of evacuation mode choice in the target area.

“…Matsumaru and Kawaguchi [29] studied the awareness on tsunami disasters to visitors at the tourist site of Enoshima, south of Tokyo city in Japan (with other studies targeting nearby cities [30][31]. Other surveys on knowledge, attitude and Practice (KAP) have been carried out in in Trinidad and Tobago [32], Vietnam [33] or after disasters already took place [7,34,35]. Generally speaking, all those studies paint a picture of increased awareness throughout the world, as exposure to disasters in other countries result in many individuals having some degree of understanding of the nature of disasters.…”

Awareness of Coastal Disasters: Case of an Impoverished Low-Lying River Mouth Community in Southern Vietnam

Impoverished communities often suffer disproportionately due to natural hazards, as their inhabitants live in lands which are particularly prone to natural hazards, and exhibit lower levels of awareness and preparedness than other communities. In the present research the authors conducted structured questionnaire surveys amongst a poor community living on top of discarded sea shells in a river bank in Phan Thiet in Southern Vietnam in order to understand the level of awareness of residents against coastal hazard. The results show that although local inhabitants appear to have a moderate to high level of awareness about flooding and typhoon hazards, the evaluation of the risk that they pose to them is moderate to low. Despite the low frequency of coastal hazards in the area, the consequences of any significant event would be disastrous, as the community is located less than half a metre above water level. Thus, it is imperative that better countermeasures are put in place in the area to improve the resilience of inhabitants and ensure the long-term sustainability of the settlement. .
