Research:
My current research interests involve using available seismological data to better understand the physical processes behind earthquakes and the implications that these have for the general public. I am interested in a range of topics including: fault mechanics, non-volcanic tremor, earthquake triggering and interaction, time varying properties of the earth, and better understanding and characterizing strong ground motion and nonlinear strong ground motion. Here in Menlo Park I am currently involved in two projects:
- *Analyzing repeating earthquakes in the Parkfield area:
- Using SVD based methods to precisely measure relative earthquake moment.
- Validating renewal models for repeating earthquakes
- Exploring earthquake interaction of repeating events.
- *Examining nonlinear strong ground motion in medium magnitude earthquakes.
*Webpages will be placed here as my research in these areas progresses.
As a Post-Doc in Washington I focused my research on non-volcanic tremor. I worked on projects that revealed the way that tremor responded to outside stresses
- Tremor triggered by teleseismic earthquakes
- Tremor triggered (modulated) by the earth and ocean tides.
As a PhD student at Stanford I worked on two topics
- Damage to Near Surface Rocks from Strong Ground Motion (Nonlinear Strong Ground Motion)
- Using source array analysis to understand the mechanics of streaks
During my undergraduate studies at UCLA, I examined seismic focusing in the
1994 Northridge Earthquake, which we found to be responsible for the large
amounts of damage in Santa Monica. Please see my publications page for
further information.
