With the Sunset Amphitheater high mobility landslide scenario, a portion of the lahar followed the path of the Nisqually River, while most of it flowed down the Puyallup River drainage, arriving at the town of Orting (population >8,000) in a little under an hour, then spreading across the valley between the Puyallup and Carbon rivers. Mount Rainier is behaving about as it has over the last half-million years, so all evidence suggests that the volcano will continue to erupt, grow, and collapse. Lahars, or volcanic mudflows, are rapidly flowing slurries of mud and boulders that destroy or bury most manmade structures in their paths. It is estimated that a major eruption of Mount Rainier would injure 31,000, kill 18,000, do $2 billion worth of agricultural damage, $4 billion worth of residential damage and $5 billion worth of commercial damage.

Listener Russ Keldorph asked KUOW. In the event of a lahar, the radio should wake up and send out an alert message. An ~25 foot thick outcrop of the Osceola Mudflow from Mt. o Density o Liquid is less dense than . According to the USGS, theres a much greater likelihood that landslides will trigger these mudflows: Scientists studying Mount Rainier have long recognized that the greatest hazard posed by the volcano is from landslides that begin high on its slopes and transform into mudflows or lahars.. Official websites use .gov ", Mount Rainier is NOT erupting. An Elliott Bay view of Mount Rainier National Park / Rebecca Latson.

According to the U.S. Geological Survey, lahars have occurred as far back as 11,000 years ago, when evidence of a mudflow apparently of landslide origin, moved across Van Trump and Paradise Parks and then down the Nisqually River., The Electron Mudflow, which took place 500 years ago, flowed 60 miles (100 km) downstream to the Puget Sound lowland. Many of the cities at risk for lahars plan and practice evacuation routes. Even though Mount Rainier has not had a "significant" eruption in the last 500 years, the United States Geological Survey (USGS) calls the volcano potentially the most dangerous one in the Cascade Range. Time could be short, and successful mitigation will depend on effective notification of people at risk, public understanding of the hazard, and prompt response by citizens. Lahars from Mount Rainier can travel for tens of miles along river valleys and reach Puget Sound. Permeable rock with clay, on the other hand, meant a longer flow distance with much higher mobility (more water in the rock).

Have a backup evacuation route in mind in case the first route becomes inaccessible. Some of these events swiftly melt snow and ice and could produce torrents of meltwater that pick up loose rock and become rapidly flowing slurries of mud and boulders known as "lahars." It would be hot, and it would melt the ice and snow. Shes talking about a possible eruption, which could happen in our lifetime. First, during an eruption on a volcano with snow and ice, the frozen material can melt and mix with volcanic debris to create a flow that rushes down river valleys on the volcano.

Everybody has all these positive vibes from the volcano, Driedger says. A video of Mount Rainier shows a lenticular cloud hovering over it on Sept. 7, 2022. Other simulations looked at lahars that travelled down the Nisqually River valley. Rainier's summit ~ most likely east of the volcano: for example, Yakima and Ellensburg ~ could easily receive several millimeters (3 inches or so) of ash from a pumiceproducing eruption of Mt. Previously, it's been thought that most of the magma that fills up the tanks of Mount St. Helens, Adams, and Rainier comes from the subduction of three minor tectonic plates beneath the North . that can respond in realtime to any lahar. KUOW, a Seattle NPR station, reported in 2018 that if Mount Rainier were to erupt, it would sound like "a rocket launching." In the case of an Electron-sized flow from the Sunset Amphitheatre on Rainier, they found that the lahar would sweep down the slopes at over 10 miles per hour with a flow front that towered over 12 feet.
