Mt Adams, Seismic activity Monitoring || Cascades Volcano Observatory Information Statement :: U.S. Geological Survey

"In September, the U.S. Geological Survey Cascades Volcano Observatory (CVO) and Pacific Northwest Seismic Network (PNSN) located six earthquakes at Mount Adams, ranging from magnitudes 0.9 to 2.0. Typically, earthquakes at this volcano are located at a rate of about 1 earthquake every 2-3 years. With just one seismic station near the volcano, monitoring capabilities are currently limited. CVO and PNSN plan to install temporary seismic stations in the Mount Adams area, which will allow detection of smaller earthquakes and better estimates of size, location, and depth, information necessary to assess the significance of the activity. Currently, there is no indication that the level of earthquake activity is cause for concern, and the alert level and color code for Mount Adams remain at GREEN / NORMAL. CVO and the PNSN will continue to monitor earthquake activity and release further updates as the situation warrants". More
