Eartquakes off the coast


Swarm of earthquakes detected off Oregon Coast - KMTR NewsSource 16 - Eugene, Oregon -Breaking News, Local Weather, Local News, Local Sports, Springfield, Oregon: "Geophysicist Robert Dziak (ZEE-ak) says they don't know what the earthquakes mean.

But he says they could be the result of magma rumbling underneath the Juan de Fuca Plate - away from the recognized earthquake faults off Oregon.

More than 600 quakes have been detected in the past 10 days. Three were of magnitude 5.0 or greater.

On the hydrophones, they sound like low rumbling thunder and are unlike anything scientists have heard in 17 years of listening.

Most are too small to be felt on shore."
