SKS/SKKS splitting and Taiwan orogeny

  1. In central and southern Taiwan, the source of the anisotropy is mainly from the vertically coherent deformation of the crust and upper mantle by left‐lateral shearing. Red arrows represent the shear directions.

  2. In northern Taiwan, the source of anisotropy may be more complicated. Both hydrated olive in the upper mantle and the extrusion at the end of a collision zone are possible sources, but other possibilities can not be excluded.

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.
