Estimating Seismic Hazards from the Catalog of Taiwan Earthquakes from 1900 to 2014 in Terms of Maximum Magnitude
Abstract
Maximum expected earthquake magnitude is an important parameter when designing mitigation measures for seismic hazards. This study calculated the maximum magnitude of potential earthquakes for each cell in a 0.1° × 0.1° grid of Taiwan. Two zones vulnerable to maximum magnitudes of Mw≥ 6.0, which will cause extensive building damage, were identified: one extends from Hsinchu southward to Taichung, Nantou, Chiayi, and Tainan in western Taiwan; the other extends from Ilan southward to Hualian and Taitung in eastern Taiwan. These zones are also characterized by low b values, which are consistent with high peak ground shaking. We also employed an innovative method to calculate (at intervals of Mw 0.5) the bounds and median of recurrence time for earthquakes of magnitude Mw 6.0-8.0 in Taiwan.
