Major Activities

Construction of a Virtual Earth (current focus on the 3D geometry of the Indonesian slab and the geodynamics of the Great Sumatran earthquake)

3D tectonic reconstruction - Pplates Using SNARK to simulate crustal deformation

associated with shear zones, and 3D slab roll-back

Not the final result - a work in progress

3D reconstruction - gOcad model of the Tethyan slab beneath Indonesia

3D visualization of slab geometry

Using gOcad to look in 3D at elongate octagons in

the conjugate fault planes generated using data from the Harvard CMT database

Structural analysis of data from the Harvard Centroid Moment Tensor Database(252 quakes since 12-26-04)

The analysis program will beavailable through ACcESS
