REPORT:
Characteristics of Debris Flows of Noneruptive Origin on Mount Shasta, Northern California


-- Blodgett, J.C., Poeschel, K.R., and Osterkamp, W.R., 1996,
Characteristics of Debris Flows of Noneruptive Origin on Mount Shasta, Northern California: U.S. Geological Survey Open-File Report 96-144, 27p.
Studies of Mount Shasta indicate that eruptive activity has occurred, on the average, once every 800 years. Debris flows and deposits of noneruptive origin, in addition to those associated with eruptive activity (lava flows, pyroclastic flows, and ash fall), inundate the fans and channels and can endanger people or property on the flanks of the mountain. This study evaluates the source and characteristics of historical noneruptive debris flows in the vicinity of Mount Shasta. -- Blodgett, et.al., 1996
