Quake swarm under Washington volcano Mount Rainier...
Nearly two dozen small earthquakes have rattled Mount Rainier over the past week, but seismologists say there’s no cause for worry.
“In the past, these swarms last a couple of days to a week or so and then die out,” said Paul Bodin, of the Pacific Northwest Seismic Network at the University of Washington.
The first of the 23 quakes struck on Sept. 11 near the volcano’s summit. The largest of the quakes registered magnitude 1.6.
