Weband the 500 year-old Electron Mudflow in the Puyallup Valley are superimposed on all valleys surrounding Mount Rainier. They illustrate areas that could be inundated if flows of those sizes occurred in each valley. A lahar flowing downvalley from Mount Rainier leaves a thick valley-bottom deposit of boulders and hard-ened mud that may envelop ... WebELECTRON MUDFLOW. This cohesive lahar in the Puyallup valley (table 2) is like the Osceola Mudflow, although it is smaller in volume. Nevertheless, the Electron is still …

WebA younger mudflow, which has been named the Electron Mudflow, originated on the west side of Mount Rainier within the Puyallup River drainage basin; the flow extended about 40 miles downvalley to the outskirts of Sumner (fig. 1) and buried the floor of the Puyallup River valley at Orting under 15 feet of rock debris and mud (Crandell, 1963b). WebThe Electron Mudflow is a recent example of such a structural collapse of the mountain’s west flank. An analysis of ash and lahar layers by Pringle, Kevin Scott and Jim Vallance at USGS shows no evidence of an …
WebDec 6, 2024 · The Electron Mudflow for example, which occurred about 500 years ago, was not associated with an eruption, so it is possible that a lahar could occur during quieter periods.” WebMar 1, 2005 · The volume of the Electron Mudflow deposits on the Puget Sound lowland was satisfactorily determined by Crandell (1971, p. 57) as slightly more than 183 million m 3. The flow deposit is overlain by reworked deposits of the flow. Its original volume (table 7) is estimated by assuming deposition near the levels of the highest medial flow deposits.
WebThe most typical example is the Electron Mudflow. Deposits of that flow, which occurred about 500 years ago, form the valley surface around Orting. Large, generally clay-rich debris flows that originated as landslides have occurred, on average, every 500 to 1000 years during the last 6,000 years at Mount Rainier. Because most Rainier landslides ...
