Three-dimensional crustal structure from dense seismic array

Three-dimensional crustal structure in the northern part of Eastern Taiwan from dense seismic array data sets

  1. Due to the dense ray coverage of body waves and seismic networks, we further apply both body wave tomography and joint inversion tomography of body and surface waves.

  2. Combined with the high resolution velocity models and the spacial distribution of these more complete aftershocks, our results clearly depict several local tectonic structures that have not been observed at the northern tip of the Longitudinal Valley, not only a suture but also a transitional area from collision to subduction.

Relocation of Eastern Taiwan Earthquakes and Tectonic Implications

Relocation of Eastern Taiwan Earthquakes and Tectonic Implications

  1. In this study, the geometric distribution of the relocated events is in general agreement with the focal mechanism solutions.

  2. According to the results from seismicity distribution and focal mechanism solutions, the seismic pattern changes greatly from the northern portion to the southern portion in eastern Taiwan.
