| Debris flows on Mount Shasta, northern California, have occurred frequently during the late Holocene in response to rapid runoff from melting snow and ice. ... The purpose of this chapter of Professional Paper 1396 is to evaluate the potential for future noneruptive debris-flow activity on Mount Shasta. Attention is restricted to "cold" flows, that is, to flows not directly related to volcanic activity. Areas where damage by cold debris flows could occur are identified on the basis of geologic, topographic, and historical evidence. -- Osterkamp, 1986 |
