Taiwan is within the link of the Pacific Ocean earthquake belt,
which causes the seismic activities to be quite often in
Taiwan. Based on the past 100-year seismic records in Taiwan,
many collapsed buildings, lots of casualties, and great economic
loss had occurred during each previous serious earthquake. The
main reason for those severe damages and losses are due to the
uncertainty and unpredictable of occurrence of an
earthquake. There were no early warning signal, sign, and time
for the people to relocate to an asylum. Thus, disaster
prevention and mitigation is a big issue for all the people and
government in Taiwan in order to properly respond to an
earthquake and to reduce the risk induced by an earthquake.
This study used the Taiwan Earthquake Disaster Loss Estimation
System (TELES), developed by National Center for Research on
Earthquake Engineering in Taiwan, to simulate. TELES is a
application tool used for earthquake condition simulation and
developed based on the data and geological conditions collected
in Taiwan. In this study, the eruption of Changhua fault was
assumed and the possible damaged areas, including buildings and
people, Fengyuan City were evaluated using TELES. An inquiry
system combining TELES, geography information system (GIS), and
asylum was developed using Visual Basic 6.0. Therefore, this
system can be used to display the results by TELES together with
the roads, hospitals, fire stations, and asylum around certain
areas. The valuable information will be useful for rescue and
damage reduction caused by an earthquake in the future.
The damages caused by the assumed Changhua fault eruption on the
studied areas, cities in Taichung, can be displayed easily using
the developed system. The combined inquiry results, including
possible damaged areas, best roads for rescue, and the closest
asylum, can be used for reference for disaster prevention and
mitigation in the future. Thus, plans for prevention,
mitigation, response, and recovery should be taken into
consideration for those potential damaged areas based on the
simulation of this study. |
