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.

Three-dimensional Vp, Vs, and Vp/Vs seismic velocity structures in the Wuyi-Yunkai orogen

Three-dimensional Vp, Vs, and Vp/Vs seismic velocity structures in the Wuyi-Yunkai orogen

  1. Tomographic Inversion with the data of the active- and passive- sources to better constrain the shallow structure.

  2. Low Vp/Vs ratios of the crust in most of Fujian area suggest the felsic crust.

  3. The shallower crust along the coastline results in high heat flow.

Seismic velocity structures in the Taiwan orogen

Seismic velocity structures in the Taiwan orogen

  1. Seismic velocity structures from the independent data sets of the TAIGER and other projects (over 2,500 temporary seismic stations used in the study)

  2. Tomographic Inversion with the data of the active- and passive- sources to better constrain the shallow structure.

  3. Two crustal roots observed beneath the Central and Coastal Ranges due to the collision between the two plates.
