Two-dimensional crustal structures of Taiwan from gravity data
Article Abstract:
An island-wide gravity survey of Taiwan was conducted from 1980 to 1987 to improve understanding of the region's tectonic structure. With this study, geologist produced the Bouguer anomaly map, which shows that the isogal trend NNE is in harmony with the overall structural trend of the island. Furthermore, the subsurface density structures are modeled along three profiles across the structural trends, which places the continental Moho 33 km beneath the Central Range, 26 km under the Coastal Plain and Western Foothills and 28 km underneath the Coastal Range in eastern Taiwan.

Three-dimensional elastic wave velocity structure of the Hualien region of Taiwan: evidence of active crustal exhumation
Article Abstract:
A study investigating the structure and dynamics of the Hualien region of Taiwan is presented. Analyzing seismograms of local earthquakes recorded during a deployment of the Portable Array of Numerical Data Acquisition II network in the region, geologists found that the fast uplift of the mountains of Taiwan are caused by compressional shortening and excess of positive buoyancy. The results also suggest that the higher velocities and extensional mechanisms in the Central Eastern Range are caused by the continuous exhumation of previously subducted continental crust.

Deep earthquakes beneath central Taiwan: mantle shearing in an arc-continent collision
Article Abstract:
A study of the deep earthquakes beneath central Taiwan reveal the tectonics of Taiwan. The island of Taiwan was formed by the impact of an island arcon the Philippine sea plate with the Eurasian continental shelf. Earthquake occurs in the mantle beneath Taiwan when the plates subduct beneath each other. The earthquakes are frequent and occur in different locations. An eastward displacement of the Eurasian mantle north of 24 degrees north causes these earthquakes which are located at depths exceeding 60 km and .
