While not erupting, Mount Hood shows signs that it is a functioning, active volcano. Mount Hood produces frequent earthquakes, and steam and volcanic gases are emitted in the area around Crater Rock near the summit. These proposed stations greatly enhance the ability of USGS–CVO to detect subtle signals beneath the volcano and determine with greater confidence whether or not the volcano poses any imminent threat of eruption.
The USGS designated Mount Hood as a very high threat volcano in its 2005 National Volcanic Early Warning System assessment (http://pubs.usgs.gov/of/2005/1164/) due of the volcano’s eruptive history, current activity and proximity to communities downstream and downwind. Seismic, GPS and volcanic gas data collected from the stations would be used as the basis for public communications and early warnings, to ensure the safety of adjacent communities as well as recreationists using the Wilderness and Forest.
The public is invited to comment on this proposal through April 27, 2015. Electronic comments may be submitted to firstname.lastname@example.org, or written comments can be sent to:
