| dc.description.abstract | Taiwan is located at the subduction zone between the Eurasian plate and
the Philippine Sea plate, prone to frequently having earthquakes occur. Ever
destructive earthquakes such as the Mino-earthquake and the Hualienearthquake
had caused collapses of buildings and interruptions to traffic.
With the economic development, people are tend to seek better job
opportunities and eduction in metropolitan areas. Taking Hsin-Chu city for
example, the establishment of the Hsin-Chu Science Park creates many highsalary
employments and attracts lots of young people to settle down nearby
districts. It causes Hsin-Chu city owns the highest fertility rate in Taiwan
compared with other metropolis which are suffering from aging population.
However, in case of earthquakes, citizens need plans for emergency
evacuation. If the designated shelters could fall short of actual demand or be
unreachable reached due to damages of roads and buildings, people might be
directly exposed in danger during evacutaion. Therefore, how to evaluate
whether the shelters are qualified to accommodate affected citizens is an
essential topic for Hsinchu City Government to take actions in advance, if a
large-scale earthquake would hit in the future.
In general, the appropriate location of a shelter should be the distance,
usually a criteria of 500m, to active fault which is recognized by the Central
Geological Survey, MOEA. In order to determine the shelter safe or not after
strong ground shaking, it could still remain operational under the damage of
III
roads and buildings nearby. This study utilized the Taiwan Earthquake
Impact Research and Information Application platform (TERIA) with a
nation-wide digitized mesh at grid-size of 500m×500m to simulate and
evaluate the 6.8-scale earthquake triggered by Hsin-Cheng fault. Herein,
both moduls of the road impact and the building impact were applied to
analyze the corresponding damages, as well as subsequent evaluation of the
evacuation problems. According to the aforementioned analysis, the
feasibility and capacity for installing shelters are accordingly suggested. | en_US |
