MOUNT HOOD, Ore. -- There's been some minor seismic activity at Mount Hood since Monday afternoon, according to the U.S. Geological Survey.
As of 11 a.m. Tuesday, more than 30 earthquakes have been recorded beneath Oregon's tallest mountain, the USGS said. The quakes have all been within one mile east-northeast of Government Camp and about five miles south of the Mount Hood Summit. They’ve been about two to three miles in depth.
All the earthquakes have probably been too small to feel, the USGS said. The maximum magnitude was 2.1.
An earthquake swarm around Mount Hood isn’t unprecedented, according to the USGS. One most recently occurred in 2014. The largest earthquake ever recorded near Mount Hood was a magnitude 4.5 on June 29, 2002.
The USGS does not believe the earthquakes signify something more is happening at Mount Hood.
“Based on similarity to past seismic sequences near Mount Hood and on past studies of seismicity in the Mount Hood area, we infer that these earthquakes are occurring on tectonic faults and are not directly related to volcanic processes occurring beneath Mount Hood,” the agency said.
On July 3, the USGS said more than 70 earthquakes had occurred beneath Mount St. Helens over the past month.
