Director, Berkeley Seismology Lab

Class of 1954 Professor, Dept. Earth & Planetary Science

Cascadia

The enigmatic Cascadia Subduction Zone lacks the continuous seismic activity seen at most convergent plat boundaries. We use a variety of Earth imaging techniques to understand tectonic processes in the region.

Alaska

Alaska is the last frontier for Earthscope. As the dense USArray spreads across the state we start to observe the dynamic processes responsible for the region’s earthquakes and volcanoes.

MyShake

MyShake is a global smartphone-based seismic network. The goal: provide global earthquake early warning.

ShakeAlert

ShakeAlert is the earthquake early warning system under construction in the United States. We have been part of this effort since its inception in 2001, and continue to work towards public alerts.

Observational Systems

Data is at the heart of all our research activities, so we also work to design, develop and implement new geophysical observational systems, as part of the Berkeley Seismological Laboratory.

The Earthquake Engineering Research Institute (EERI) sent a reconnaissance team to Mexico City in October 2017 to learn about the Mexican earthquake early warning system and its performance in the September 2017 earthquakes. Team members pictured (right to left) Richard Allen, Scott Miles (U. Washington), Diego Otegui (U. Delaware) and Elizabeth Cochran (USGS).

Graduate student William Hawley publishes his 3D image of the Cascadia subduction zone in Science. In it he reveals an accumulation of low velocity material beneath the hinge of the subduction zone that is interpreted as accumulated low viscosity material separating the oceanic lithosphere from the mantle below. September 2016.

Graduate student Robert Martin-Short published his observations of mantle flow beneath the Juan de Fuca plate in Nature Geoscience. He interprets them to indicate a decoupling between portions of the Juan de Fuca plate and the mantle below. December 2015.

Overview map of the Cascadia Subduction Zone and the Cascadia Initiative seismic deployment. The Cascadia Initiative will study plate tectonic processes across the entire Jan de Fuca plate including the creation and destruction of the plate, and earthquake processes along the megathrust.

Richard’s group BBQ. May 2015

Two weeks after the Napa earthquake rattled the San Francisco Bay Area, the Berkeley Seismology Lab hosted the Third International Earthquake Early Warning meeting to discuss progress in early warning research and the path to a public system in the United States. Participating in the opening session (pictured here) where (left to right) Richard Allen, state Sen. Jerry Hill, Lt. Gov. Gavin Newsom, state Sen. Alex Padilla, Office of Emergency Services director Mark Ghilarducci, San Francisco Mayor Ed Lee and USGS acting director Suzette Kimball.
