PORTLAND, Ore. (KOIN) — A small swarm of earthquakes has been recorded on Mt. Hood since Monday.
The Pacific Northwest Seismic Network website shows the swarm near Government camp, most registering between 1.2 magnitude to 2.3.
Steve Malone, Professor Emeritus in the Department of Earth & Space Sciences at the University of Washington, told KOIN 6 that the swarm started Monday. He said it appears to be similar to other swarms in the past and is located south-south west of the summit in the area of Government Camp.
The last swarm of this type was recorded in the spring and summer months of 2016.
Malone said it’s too early to tell if this swarm is significant. Past swarms have died out within a week.
Small seismic activity on Mt. Hood, a potentially active volcano, is not uncommon. On average, 0 to 3 earthquakes within 10 km of the volcano are reported each week.
