Earthquake Science Center


The Earthquake Science Center in Menlo Park, California is the largest USGS research center in the West and houses extensive research laboratories, scientific infrastructure, and library facilities.

Our priority is to continue the important work of the Department of the Interior and the USGS, while also maintaining the health and safety of our employees and the community. Based on guidance from the White House, the CDC, and state and local authorities, we are shifting our operations to a virtual mode and have minimal staffing within our offices.

Federal Agencies Partner to Strengthen ShakeAlert Earthquake Early Warning Capacity Along the West Coast

A lone solar panel in the middle of California’s largest national forest is powering a seismometer able to detect Earth’s vibrations, a piece of the puzzle necessary to help protect life and property by providing critical seconds of warning that an earthquake is occurring and shaking is imminent.

Characteristics of frequent dynamic triggering of microearthquakes in Southern California

Dynamic triggering of earthquakes has been reported at various fault systems. The triggered earthquakes are thought to be caused either directly by dynamic stress changes due to the passing seismic waves, or indirectly by other nonlinear processes that are initiated by the passing waves. Distinguishing these physical mechanisms is difficult...

Ensemble ShakeMaps for magnitude 9 earthquakes on the Cascadia Subduction Zone

We develop ensemble ShakeMaps for various magnitude 9 (⁠M">MM 9) earthquakes on the Cascadia megathrust. Ground‐shaking estimates are based on 30 M">MM 9 Cascadia earthquake scenarios, which were selected using a logic‐tree approach that varied the hypocenter location, down‐dip rupture limit, slip distribution, and location of...

Generalizing the inversion‐based PSHA source model for an interconnected fault system

This article represents a step toward generalizing and simplifying the procedure for constructing an inversion‐based seismic hazard source model for an interconnected fault system, including the specification of adjustable segmentation constraints. A very simple example is used to maximize understandability and to counter the notion that an...
