A sudden surge in earthquake activity at Mount Adams, Washington’s largest active volcano, has scientists scrambling to install new monitoring equipment.
Could we be on the verge of a new volcanic disaster?
At a Glance
- Mount Adams experienced six small earthquakes in September, the highest monthly total since 1982
- Scientists are deploying temporary seismic monitoring stations to gather more data
- The volcano typically experiences only one earthquake every two to three years
- Despite increased activity, there’s no immediate cause for concern or indication of an imminent eruption
Unusual Seismic Activity Prompts Closer Scrutiny
In a surprising turn of events, Mount Adams, Washington’s gentle giant, has suddenly become much, much more active. The U.S. Geological Survey (USGS) reported an unprecedented spike in earthquake activity at the volcano in September, recording six small tremors in a single month. This marks the highest number of quakes in any given month since monitoring began in 1982, raising eyebrows among scientists and prompting a swift response from authorities.
Mount Adams, standing at over 12,000 feet tall and 18 miles wide, typically experiences minimal seismic activity, with an earthquake occurring only once every two to three years. This sudden increase in activity has caught the attention of volcanologists and seismologists, who are now racing to gather more data to understand the significance of these events.
In response to this unusual seismic uptick, the USGS Cascades Volcano Observatory (CVO) is taking proactive measures. Scientists are deploying temporary seismic monitoring stations south and southwest of Mount Adams, with permission from the U.S. Forest Service. These additional stations will provide real-time data transmission to both the CVO and the Pacific Northwest Seismic Network (PNSN), allowing for more comprehensive monitoring and analysis of the volcano’s behavior.
“We are now working to gather more data to assess if this is really something unusual or just a volcano talking to us a bit more than it normally does,” Jon Major, the CVO scientist-in-charge, told Live Science.
This enhanced monitoring effort is crucial for understanding the recent seismic events and determining if further actions are needed. It’s a testament to the vigilance of our scientific community in safeguarding public safety and expanding our knowledge of volcanic processes.
No Immediate Cause for Alarm
Despite the increase in seismic activity, experts emphasize that there’s no immediate cause for concern. For now.
The recent earthquakes were small, with magnitudes ranging between 0.9 and 2, well below the threshold that humans can feel. As Major pointed out, “Had one been standing at or near Mount Adams one would not have felt these earthquakes.”
Mount Adams usually sees an earthquake every couple years. There were six in September 2024 alone. Scientists are sending resources out for closer monitoring. https://t.co/SWKFMbwmyV

The USGS maintains that there is no indication of an imminent eruption, and the alert level for Mount Adams remains at Green and Normal. This cautious yet reassuring stance underscores the importance of continuous monitoring and the value of our advanced early warning systems.
With our luck lately, though, it’s not hard to imagine things changing very quickly…
