We have regular drills here for these, so far nothing. But . . Lahars Lahars at Mount Rainier? During the past 10,000 years, there have been at least 60 different lahars of various sizes originating from Mount Rainier (Hoblitt and others, 1995:5). There are now over 100,000 homes and over 200,000 Puget Sound residents that work in buildings located on these deposits (Krakauer, 1996:34). The largest of these lahars is the Osceola Mudflow that occurred approximately 5,600 years ago and extends to the Port of Tacoma including the areas now inhabited by the towns of Orting, Buckley, Sumner, Puyallup, Enumclaw and Auburn (Hoblitt and others, 1995:5). A more recent lahar, the Electron Mudflow, originated as a sector collapse from what is now known as the Sunset Amphitheater around 600 years ago. The deposits left from the Electron Mudflow are 30 yards deep at the beginning of the Puget Sound lowland area and at least 6 yards deep at the town of Orting (Hoblitt and others, 1995:5). The following hazard map illustrates the areas at risk from future lahar activity. 600 years ago we had no humans, no burning of fossil fuels, nothing, just happened. Regarding of one poster on here who believes he/she is the epitome of brillance in all things geological, many of our rivers here that are fed by glacial/snow melt are barely ankle deep as yet. If a lahar occurred 600 years ago and was not caused by man, I fail to see how we could be causing one yet. IF we were able to cause them, then by God let's do something to prevent them, huh? But to my knowledge nothing is being done, because nothing CAN be done.
