Volcanoes tend to have seismicity that waxes and wanes over time. That’s considered normal and not necessarily a cause for concern. Let’s check on Mount Adams to see what USGS scientists are doing to learn more about its recent earthquake activity and what it could mean for this Cascade Range volcano.

Mount Adams earthquake location map and depth chart.
The earthquakes were detected on seismic station ASR2, a PNSN-operated station located about 7.5 miles (12 km) from the summit of Mount Adams, along with other stations much farther away from the volcano.

Mount Adams earthquakes time vs depth plot 1982-2024
During September 2024, the U.S. Geological Survey Cascades Volcano Observatory (CVO) and Pacific Northwest Seismic Network (PNSN) located six earthquakes at Mount Adams. For comparison, earthquakes at this volcano are typically located at a rate of about 1 every 2-3 years.
