Earthquake hazard mitigation

Earthquakes are one of the most frequent natural hazards in Taiwan. To mitigate the level of their damage, the development of early warning system is of great importance on one hand (Wu et al., 2011); gaining better understanding of ground motion relations, such as medium attenuation, source characteristics (e.g. directivity), and site effects, is also critical on the other hand. With derived high resolution velocity models, we have analyzed the source properties of Nantou (Lee et al., 2015) and Ruisui earthquakes (Lee et al., 2014) and demonstrated the capability of capturing realistic ground motions to some extent, especially across mountains and within basins, which could give us better insights into complicated wave propagation and help the hazard mitigation ultimately.
