Mount Rainier, the active volcano towering above southwestern Washington state, started rumbling — very lightly — on Tuesday.

A minor, 3.3-magnitude earthquake struck in Northern California on Monday, according to the United States Geological Survey.

A map displays the likelihood of damaging earthquake shaking in Alaska. USGS. In the last two centuries, 37 states have seen an abundance of magnitude 5 earthquakes, according to the study.

The U.S. Geological Survey said it and other agencies were monitoring the situation and would issue additional alerts "as ...

Mount Rainier on Tuesday experienced its largest seismic activity since 2009, with a swarm of small earthquakes detected.

This map shows locations of earthquakes of magnitude 2.5 or larger. Red circles mark earthquakes from 1974-2002; green ones occurred before 1974.

A new earthquake fault mapping study provides compelling evidence of seismic hazards in Turkey and Syria following the 2023 earthquakes. Researchers from UNC-Chapel Hill, USGS, and global teams ...

Earthquakes are caused by a sudden slip of a fault or fracture in Earth’s crust. Tectonic plates are constantly moving slowly, but their rough edges often contain faults and get snagged.

Using this map, researchers chose spots to dig trenches across the fault to study past earthquakes. These trenches let scientists examine layers of soil that shifted during old quakes.

Nearly 75% of the U.S., including Alaska and Hawaii, could experience a damaging earthquake sometime within the next century, USGS study finds.

The U.S. Geological Survey's new seismic hazard maps, released this week, show two more earthquake faults in Western Washington: one near the Canadian border, the other east of Port Angeles.
