Future Eruptions at Glacier Peak
The typical style of eruption at Gla
Future eruptions from Glacier Peak will very likely be preceded by earthquakes, and possibly by measurable swelling of the volcano and emission of volcanic gases. All of these signals could be detected by monitoring equipment operated by the USGS and the Pacific Northwest Seismic Network (PNSN) as long adequate sensor networks are in place ahead of time. The USGS also works with Federal, State, Provincial, and local agencies to prepare for disruption that might accompany renewed activity. A coalition of these agencies, known as the Mount Baker-Glacier Peak Facilitating Committee, has drafted a plan outlining how agencies will work together at the first sign of unrest at Mount Baker or Glacier Peak. If Glacier Peak were to reawaken, the USGS would rapidly deploy additional monitoring instruments and, together with these agencies, establish a local volcano observatory and command center that would keep nearby communities informed of developments.
