Research Description

Earthquake Rupture Processes and Hazard Mitigation: Kinematics and dynamics of fault rupture. Earthquake initiation processes. Rapid magnitude determination from P-wave arrivals. Earthquake early warning systems.

Natural Hazards: Effects and Mitigation

3D Structure and Processes of the Earth's Interior : Tomographic imaging of the Earth's interior to constrain 3D structure using integrated seismic techniques. Mapping of anisotropic structure to determine strain fields and flow in the Earth's mantle. Particularly interested in mantle upwelling processes, coupling with crustal deformation and surface volcanism.

Earthquake alert system may be coming

The San Francisco Chronicle recently reported on the work of Richard M. Allen, Director of the UC Berkeley Seismological Laboratory, for helping to develop an early warning system that flashes imminent danger when a damaging earthquake is about to strike.
