We construct the 3D Chelungpu thrust model based on detailed surface geology, several published, unpublished seismic lines and wells. These data clearly show that the fault actually runs parallel to bedding and flattens out to an upper detachment at 5 to 6 km depth. This new fault model is independent of coseismic displacement and seismic measurement and therefore can be adopted for further comparison and inversion studies.

The Chinese Tien Shan is one of the most active intercontinental mountain of the world. This project involves seismic profiles, well data, surface geology, and remote sensors to constraint the most recent deformation on the Central and Western  Tien Shan.

We look for the relationship between the surfaces deformation and the underlying process and the collision between The Pamir Massif and the Tien Shan at the north western corner of the Tarim Basin.

The initial ideal relationship between area relief-shortening- detachment depth  has been tested in 4 seismic examples using the new area thickness relief method (Ferrari et al. 2004).
We look into the  graph of area excess vs. height over the detachment  as well as other information from the detail analysis of the detachment fold to understand how the deformation is driven into this simple structure and compare the results with the kinematic models proposed early.

3D fault models of San Jacinto, Elsinore and southern San Andreas Fault systems, California.

We relocated around 70,000 earthquakes of Southern California from datasets of catalog (SCEDC, Southern California Earthquake Data Center), Hauksson (2000), Richards-Dinger and Shearer (2000) based on double-difference (Waldhauser and Ellsworth, 2000) and also collapsing methods (Jones and Stewart, 1997) to be the basis of our fault models (Figure 2). The relocated earthquakes clearly form several tight clusters, which can be correlated to surface breaks and traces very well. Based on relocated earthquakes and surface traces, therefore, we successfully mapped around 50 faults of San Jacinto, Elsinore and southern San Andreas Fault systems.
