A regional map illustrates the extent of inundation by the case-history flows, the largest of which originated as debris avalanches and moved from Mount Rainier to Puget Sound. The paleohydrologic record of these past flows indicates the potential of inundation by future flows from the volcano. a map of the volcano and its immediate vicinity shows examples of smaller debris avalanches and debris flows in the 20th century. -- Scott and Vallance, 1995 |
