Earthquakes in Taiwan Collision Zone and Hualien Today

The whole island of Taiwan is an active collision zone: the Longitudinal Valley Fault in the east, the thrust faults of the western foothills and the Ryukyu subduction zone offshore all produce strong earthquakes. Hualien on the east coast is among the most frequently shaken cities in East Asia.
