Officials at the United States Geological Survey have tracked over 300 earthquakes beneath Washington State's Mt Rainier from July 8-10.

Volcanoes are rumbling as scientists monitor earthquakes at Washington's Mount Rainier and Alaska's Iliamna volcano.

Earth’s continents may look fixed on a globe, but they’ve been drifting, splitting and reforming over billions of years – and they still are. Our new study reveals fresh evidence of rhythmic pulses of molten rock rising beneath east Africa, reshaping our understanding of how continents break apart.

Volcanoes in the United States that have been active since spring woke up, brushed themselves off, and then went back to sleep. Two volcanoes, one in Alaska and one in Hawaii, are experiencing active eruptions that are minimal and not very dangerous.

A powerful undersea earthquake struck off the southern coast of Alaska on Wednesday, setting off a tsunami advisory and prompting concern along the state’s remote peninsula region.

Seismicity has decreased” from 30 events per hour at the peak to a few per hour as of Saturday morning, the U.S. Geological Survey said Saturday.

One of the most famous mountains in Washington, Mount Rainier, has been rumbling over the last day due to the amplified seismic activity.

The series of earthquakes is the first major swarm of seismic events since 2009. Is it safe if you’re planning on visiting?

Mount Rainier, the active volcano towering above southwestern Washington state, started rumbling — very lightly — on Tuesday. A swarm of small earthquakes was detected under the mountain triggering focused monitoring from officials. But researchers have determined there is no current threat of an eruption.
