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. With just one seismic station near the volcano, monitoring capabilities are currently limited to locating earthquakes with magnitudes greater than approximately 1.0. Smaller earthquakes have also occurred over the last few months, but they were only recorded on ASR2 and as a result seismologists have been unable to locate them.
