Why Mount Rainier is the US volcano keeping scientists up at night

Mount Rainier in Washington poses a lahar threat to Tacoma and Seattle due to past debris flows. Monitoring systems and evacuation drills aim to prepare for potential lahars impacting nearby communities.

Why Mount Rainier is the US volcano keeping scientists up at night

Mount Rainier in Washington state, despite not erupting significantly in the last 1,000 years, concerns US volcanologists due to the threat it poses to surrounding communities like Tacoma and Seattle. The main worry is not lava flows but lahars, fast-moving debris flows caused by melted ice and snow during eruptions. These lahars could impact densely populated areas within a short timeframe, similar to the devastating 1985 lahar in Colombia. Mount Rainier's potential lahar scenarios have been modeled, indicating risks to areas like Orting and the Nisqually River Valley. To prepare for such events, a lahar detection system has been set up on Mount Rainier, including real-time data transmission and various sensors. Evacuation drills involving thousands of students have also been conducted to practice responses to potential lahars. The volcano's history of lahars and the ongoing monitoring efforts highlight the importance of preparedness for such natural hazards.

> The snowcapped peak of Mount Rainier, which towers 4.3 kilometers (2.7 miles) above sea level in Washington state, has not produced a significant volcanic eruption in the past 1,000 years.

Is it possible that other nearby eruptions (St Helens) are releasing the pressure that would otherwise cause an eruption at Rainier?

Would be interesting getting a text that pure destruction is approaching at 4 m/s and will reach your location in 30 minutes.

Not sure what I would do. Wrap my car with metal, and hope for the best?

I feel like the really scary prospect is the lager causing a dam failure. I’ve read a few articles from NYT talking about the potential for atmospheric rivers to overwhelm dams in california, causing a cascading collapse. From memory, the potential casualties are incredibly grim (like hydrogen bomb grim). I honestly don’t know what can be reasonably done though. The possibly range is too wide and the timeline too long.
