An earthquake swarm at Mount Hood is ongoing. The earthquakes are associated with regional faulting and are not a sign of changes in volcanic activity.
Since noon local time on January 17, there have been over 100 individual earthquakes in an area south of the summit of Mount Hood. At the time of this statement, the PNSN has located several 10's of these earthquakes with a maximum magnitude of M2.7 and depths mostly around 5 km (3 mi) below sea level. Swarms at Mount Hood are common and account for most of the seismicity at the volcano; they can last hours to days. The location of the earthquakes is similar to other swarms in this area that occurred in 2009, 2012, 2014 and 2020.
