Scientists listening to underwater microphones have detected an unusual swarm of earthquakes off central Oregon, something that often happens before a volcanic eruption — except there are no volcanoes in the area.
There have been more than 600 quakes over the past 10 days in a basin 150 miles southwest of Newport. The biggest was magnitude 5.4, and two others were more than magnitude 5.0, SOU reported.
On the hydrophones, the quakes sound like low thunder and are unlike anything scientists have heard in 17 years of listening, Disk said. Some of the quakes have also been detected by earthquake instruments on land.

This is very intriguing to me since anything in science that is odd generally is, but also more obviously because I live in the general area.
I must confess I am a little uneasy, since this could be a predecessor event before a megathrust earthquake or a similar event on the scale of the speculated 'big one' that is suppose dot hit California.
