More than 100 earthquakes shook near an Oregon volcano in one day, the U.S. Geological Survey said.
An area south of Mount Hood near Portland was hit by a swarm starting at noon Sunday, USGS said.
“An earthquake swarm at Mount Hood is ongoing,” USGS said on Facebook. “The earthquakes are associated with regional faulting and are not a sign of changes in volcanic activity.”
The quakes did not cause any damage, and they are not a sign of impending volcanic activity, USGS said. Many of the earthquakes were small in size.
Several earthquakes shook with a maximum magnitude of 2.7 and depths of about 3 miles below sea level, according to USGS. Via – The Sacramento Bee
