Swarm of quakes around Mount Rainier

Scientists in Washington state say there has been a spate of earthquakes around Mount Rainier in recent weeks but that it isn’t a concern.Pacific Northwest Seismograph Network’s Bill Steele says the activity is normal. But he says scientists are watching the volcano a closer because of two quakes recorded Friday. The first was a 3.4 magnitude quake that struck west of the mountain near Ashford. It was followed about an hour later with a 2.9 magnitude quake under the volcano.University of Washington emeritus professor Steve Malone says data shows at least seven earthquakes in two weeks. He says there are frequently earthquakes around Rainier, averaging several each month, and that recent activity shouldn’t cause alarm.

INFORMATION ON MOUNT RAINIER

Mount Rainier is a massive stratovolcano located 54 miles (87 km) southeast of Seattle in the state of Washington, United States. It is the most topographically prominent mountain in the contiguous United States and the Cascade Volcanic Arc, with a summit elevation of 14,411 feet (4,392 m).Mt. Rainier is considered one of the most dangerous volcanoes in the world, and it is on the Decade Volcano list. Because of its large amount of glacial ice, Mt. Rainier could potentially produce massive lahars that would threaten the whole Puyallup River valley.
