A map released by USGS Tuesday revealed that the new swarm adds to the hundreds, and possibly thousands, of earthquakes recorded at Mount Rainier since 2020.
However, USGS did note that this was the largest swarm in the area since 2009.
Despite the increased seismic activity, officials said that there was no cause for alarm. The volcano’s alert level was left at ‘normal’ following the tremors.
The USGS Cascades Volcano Observatory (CVO) added: ‘Instruments do not show any detectable ground deformation at the volcano, and no anomalous signals have been seen on the infrasound monitoring stations.’
Although an eruption doesn’t seem imminent, Mount Rainier remains one of the most active volcanos in the Pacific Northwest’s Cascade Range, and a devastating eruption remains a real possibility in the near future.
