My primary research interest is understanding the mechanics of Earth's interior, especially in the crust and the mantle. What is the mechanism of plate tectonics, and which forces drive it? Are the plates driven by edge forces, that is by slab pull and ridge push, or does mantle convection have an active role in plate driving? And also: How strong is the lower crust and how does it influence crustal mechanics (detachment, block rotation)? How strong are major earthquake faults such as the San Andreas? And how are they loaded before there is a large earthquake? Are the faults weak or strong? And what role do crustal fluids play in this? My research employs mainly seismology to approach these questions.  DETAILS...
