Tsunami Inundation Map and Its Application on Evacuation Planning in Taiwan

Abstract

The casualty and impact induced by the 2011 Tohoku tsunami event and the earthquake in Japan drew considerable attention of Taiwanese government and civilian to review what we have accomplished for tsunami disaster prevention. However, at that time, there was no applicable tsunami potential data for local governments in Taiwan to draw the tsunami evacuation plans. Therefore, the simulation result is adopted in this study to produce the first version of tsunami inundation maps for coastal cities/counties in Taiwan. Furthermore, a planning guideline including analytical procedure and methodology is proposed to help local governments make tsunami evacuation plans using tsunami inundation maps. Examples are given in each analytical step to illustrate typical outcomes and suggestions on planning based on local conditions. This guideline and tsunami inundation maps have been submitted to central and local governments for evacuation planning. The application in one county is chosen as an example to demonstrate the practical achievement of this study. A thorough tsunami evacuation planning associated with education and training is crucial to disaster prevention of tsunami.

The Study of the Coastal Management Criteria Based on Risk Assessmeant: A Case Study on Yunlin Coast, Taiwan

“…Nevertheless, Taiwan is located in the Circum-Pacific seismic zone, and the threat of tsunamis is not negligible. Particularly, the potential threat of tsunamis originating from the Manila Trench, the East Luzon trench, and the Ryukyu trench is of concern (Lin et al, 2015; Wu and Huang, 2009; Wu et al, 2015) [39][40][41]. Therefore, the tsunami hazards are included in consideration.…”

Development of a decision support system for tsunami evacuation: application to the Jiyang District of Sanya city in China

“…Road condition is a very important factor in both horizontal and vertical evacuations, as the evacuation of a large number of people in a short time may lead to road congestion, especially in a populous coastal city. For example, on 11 April 2012, thousands of people were stuck in a traffic congestion after a tsunami warning was issued in Indonesia (Wu et al, 2015). Evacuation managers need to know which roads are prone to congestion.…”
