MT. ADAMS, WA – In response to a notable spike in seismic activity, scientists have begun installing new monitoring equipment around Mount Adams, Washington’s largest active volcano. The heightened earthquake activity has raised concerns and prompted researchers to enhance their observational capabilities.
Typically, Mount Adams experiences an earthquake every two to three years; however, in September 2024 alone, there were six recorded earthquakes—marking the highest monthly total since monitoring began in 1982. The unusual increase in seismic events has led scientists to take proactive measures.
Currently, there is only one permanent seismic monitor situated approximately six-and-a-half miles from the volcano. To improve monitoring, scientists are deploying additional temporary sensors in the area. These new monitoring stations will record seismic vibrations, providing researchers with more detailed data regarding the activity occurring beneath the volcano.
“Right now, there’s only one monitor within about six-and-a-half miles of the volcano,” said Jon Major, Scientist-in-Charge at the USGS Cascades Volcano Observatory. “With only one monitor, it’s very hard to do really good locations. It’s really difficult to get accurate depth of the earthquakes.”
Despite the increased seismic activity, Major reassured the public that there is no immediate cause for alarm. “At the current time, there’s no cause for concern. We’re keeping what we call our alert-level status at ‘normal,’” he stated. “There’s a good chance this is just background activity at the volcano.”
Mount Adams, located in south-central Washington about 30 miles north of the White Salmon-Hood River area, is considered a “High Risk” volcano according to the USGS. While the recent uptick in seismic events is being closely monitored, Major emphasized that there is currently no evidence suggesting an impending eruption.
As the new sensors are deployed, scientists will be able to gather more comprehensive data, allowing for improved understanding and assessment of the volcanic activity. The ongoing research aims to enhance safety measures and preparedness for the surrounding communities while continuing to monitor the geological behavior of this active volcano.
