This week, the U.S. Geological Survey Cascades Volcano Observatory, in cooperation with the U.S. Forest Service and Mount Hood National Forest, will install three new volcano monitoring stations on the flanks of Mount Hood. These stations will substantially improve the ability of CVO scientists and their partners to detect and provide warning of any changes in earthquake activity, ground deformation or volcanic gas emissions that may signal an increase in volcanic activity and a subsequent danger to people and property.
The new Mount Hood monitoring sites will consist of three sets of co-located seismic and GPS stations situated within 2.5 miles of the summit. One ground-based continuous volcanic gas monitoring station will be installed at a later date. The stations will be constructed with minimal impact on the environment: they will be located away from trails and painted to blend in with the surroundings. A helicopter will be used to deliver equipment via external sling load to the sites during construction, and USGS personnel will access the sites by foot. The installation work is not expected to affect other recreational uses of the Mount Hood National Forest.
