After Salton Buttes, now Mt. Hood is swarming too: M3.9 earthquake and series of quakes on June 5, 2021
At this time, seismologists at the Cascades Volcano Observatory and Pacific Northwest Seismic Network do not believe this swarm signifies a change in volcanic hazard at Mount Hood, but will continue to monitor the swarm and will issue further updates as the situation warrants.

The available data are insufficient to establish a pattern of volcanic activity to determine the likelihood of eruption. The high heat flow from the area and relatively young age of Salton Buttes, however, attest to the potential for future eruptions.
So what’s going on on the West Coast of the US? Are all volcanoes going to erupt together?
