Earthquake Monitoring at Newberry Volcano
Newberry Volcano was once thought to be one of the most seismically quiet of the monitored volcanoes in Washington and Oregon before a major seismic network upgrade in 2011. Since the new stations were installed, there have been an average of 10-15 earthquakes located per year by the PNSN within the caldera.
Earthquake Hazards at Newberry Volcano
Earthquakes are rare in the region but could accompany both the gradual spreading of the region east of the Cascades crest (associated with Basin and Range extension) and eruptive activity at Newberry Volcano.
