Lava in Hawaii, seismic shaking in Alaska and underwater rumblings near Oregon. Scientists say it’s not the end of the world, but it’s definitely worth watching.

A seismologist from Seattle discussed recent volcanic activity across the United States. Here's what you should know.

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

This is now the largest recorded earthquake swarm at Mount Rainier since seismic monitoring at the volcano began in 1982, the Cascades Volcano Observatory said. With quakes ongoing, the swarm has already surpassed a major event in 2009 “in terms of magnitude, total events, event rate, and energy release.”

A 6.2 magnitude earthquake struck off Panama's Pacific coast on Monday, approximately 130 miles south of Punta Burica. The quake, occurring at a depth

Over 200 earthquakes have been detected around Mount Rainier, Washington, raising eyebrows during the biggest swarm of tremors in nearly two decades.

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.

Mount Rainier is an active stratovolcano 45 miles southeast of Tacoma and 60 miles south-southeast of Seattle. Its last eruption was "a light dusting of ash" in 1894, the USGS said in a report. Large eruptions haven't occurred for more than 1,000 years.

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

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.
