Characterizing Surface Deformation From 1981 To 2007 On Mount Baker Volcano, Washington, Brendan E. Hodge

WWU Graduate School Collection

Surface deformation studies at active volcanoes are used to detect changes to magmatic source regions beneath the volcano. At Mount Baker, Washington, continued elevated gas (CO₂ and H₂S) and heat flux from fumaroles in Sherman Crater indicate the presence of a degassing magma reservoir. Campaign geographic positioning system surveys in 2006 and 2007 provide slope distance measurements of all 19 trilateration lines on Mount Baker. These data are compared with previous slope distance measurements acquired in 1981 and 1983 with electronic distance measurement. The results indicate that surface deformation has occurred on Mount Baker during the last …

A Contemporary Review Of 1975-1976 Elevated Activity Levels At The Mount Baker Complex, Washington, And Current Community Awareness Of Volcanic Hazards, Janna Juday

WWU Graduate School Collection

This investigation seeks to understand the changes in the associated volcanic and human systems during and after the 1975-1976 sudden thermal events at Mount Baker volcano. Included are reviews of some of the conclusions made by scientists from the U.S. Geological Survey and universities around the U.S. during that event. A questionnaire was also presented to people in communities around the volcano to outline current understanding of volcanic activity and hazards associated with Mount Baker.

The source of the Mount Baker thermal activity in 1975-1976 was never conclusively identified at the time. There appears to have been a small decrease …
