Three-Dimensional Modeling of the Xichang Crust in Sichuan, China by Machine Learning
Seismicity and distribution of earthquakes can provide active fault structural information on the crust at a regional scale. The morphology of faults can be derived from the epicentral distribution of micro-earthquakes.

3-D Crustal Velocity Structure in Northwestern Greece
— The three-dimensional crustal velocity structure in the area of the northwestern Greek mainland was determined by P-wave travel time inversion, applying a two-step tomography procedure. The data set consists of the travel-time residuals of 584 well located earthquakes.

Crustal and upper mantle velocity structure in Yunnan, Southwest China [PDF]
Abstract Four wide-angle seismic profiles acquired in analogue form in the 1980s from Yunnan, Southwest China, are re-digitized and re-interpreted for a detailed P-wave velocity structure of the crust and lithospheric mantle. The results reveal that the crust can be divided roughly into upper, middle and lower crusts with bottom depths of 17–25, 26 ...
