RESEARCH

Where in the World is the Berkeley Active Tectonics Group?
While focusing on tectonic problems close to home in California, our interests extend world-wide.

Hilina Faults, Hawaii Bhuj Earthquake, India



Below you will find a list of our group research projects, both past and present, organized by the problem each project is attempting to address. Please note that many of our projects should probably be listed in multiple categories because they address several interconnected issues. While that makes organizing and browsing this web page more difficult, it makes the research more exciting!
