Earthquake Science Center

Home

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.

ShakeAlert Earthquake Early Warning Delivery for the Pacific Northwest

Starting March 11, 2021, ShakeAlert®-powered earthquake early warning alerts will be available for delivery directly to wireless devices in Oregon. In May 2021, Washington state will follow suit and complete the ShakeAlert public alerting rollout across the entire West Coast. California enabled ShakeAlert-powered alerts in October 2019.

The Disaster that Helped the Nation Prepare for Future Earthquakes: Remembering San Fernando

The San Fernando earthquake struck Southern California 50 years ago, killing 64 people and costing over $500 million in damages. The quake prompted federal, state and local action to reduce earthquake risks and bolster public safety.

Physics‐based evaluation of the maximum magnitude of potential earthquakes induced by the Hutubi (China) underground gas storage

The world’s largest underground gas storage facility in Hutubi (HUGS), China, is a unique case where cyclic gas injection‐extraction induced both seismicity and ground deformation. To assess the potential for future induced seismicity, we develop a framework physically based on a well‐constrained hydro‐geomechanical model and on fully coupled...

Earthquake magnitudes from dynamic strain

Dynamic strains have never played a role in determining local earthquake magnitudes, which are routinely set by displacement waveforms from seismic instrumentation (e.g., ML">MLML⁠). We present a magnitude scale for local earthquakes based on broadband dynamic strain waveforms. This scale is derived from the peak root‐mean‐squared strains...

Rapid strain release on the Bear River fault zone, Utah–Wyoming—The impact of preexisting structure on the rupture behavior of a new normal fault

Earthquake clustering (grouping in space and time) is a widely observed mode of strain release in the upper crust, although this behavior on individual faults is a departure from classic elastic rebound theory. In this study, we consider factors responsible for a cluster of earthquakes on the Bear River fault zone (BRF), a recently activated...
