20 Largest Earthquakes in the World Since 1900
A list of the 20 largest earthquakes in the world.
Earthquake Response
USGS scientists conduct research and provide scientific response to damaging earthquakes in active tectonic regions of the United States and around the world.

Studying Earthquake Hazards and Rifting Processes in the Imperial and Coachella Valleys
Tectonic Geomorphology and Near-Field Geodesy
Repeated earthquakes shape the Earth over the millennia and fault zones often have unique and diagnostic landforms caused by the faulting process. In order to measure the rate at which the Earth’s crust deforms between, during and after earthquakes, precise measurements need to be made along active faults zones.
Rock Physics Lab
There are currently two main Experimental Rock Physics Laboratories in the Earthquake Science Center in Menlo Park, California. These laboratories specialize in generating earthquakes under controlled conditions.
Cone Penetration Testing (CPT)
This research focuses on the ability to determine what areas are more prone to experiencing effects such as liquefaction and landslides when there is shaking from an earthquake.
