America's deadliest volcano enters unprecedented 72-hour tremor phase as eruption threat looms over millions
Daily Mail UK ^ | November 19, 2025 | CHRIS MELORE, US ASSISTANT SCIENCE EDITOR

Washington's Mount Rainier has suddenly awoken and is buzzing with almost nonstop activity for days, stoking fears that an eruption could come soon.

This towering stratovolcano looms over more than 3.3 million people across the Seattle-Tacoma metro area, threatening to cripple entire communities with ashfall, flooding, and catastrophic mudflows if it erupts.

Since Saturday, Mount Rainier has been experiencing constant vibrations beneath the surface, thousands of tiny tremors blending into one another.

The constant seismic rumblings were detected by the Pacific Northwest Seismic Network (PNSN), where seismometers on Mount Rainier have recorded three straight days of nearly nonstop, high-energy seismic signals across the west flank of the volcano.

Unlike the seismic activity tied to major earthquakes, the patterns being seen in Washington look more like a volcanic tremor, a type of nonstop hum or roar that begins when magma, hot water, and gas move around inside a volcano.

It doesn't mean Mount Rainier is going to erupt at any moment, but it is a warning sign that volcanic activity could eventually build towards a critical level.

Geologists will be watching for key signs of this volcanic tremor escalating, including its severity increasing in the coming days, actual earthquakes starting inside the volcano, and the ground at Mount Rainier beginning to swell.

When this volcano eventually explodes, it won't be scorching lava flows or choking clouds of ash that threaten Americans, but the lahars: violent, fast-moving mudflows that can tear across entire communities in mere minutes.

Large lahars can crush, bury, or carry away almost anything in their paths, according to the US Geological Survey (USGS).

“When it goes, next week, next year or next century, it’s going to kill many hundreds of thousands with little warning.

Even if there is substantial geological warnings, people will not heed them.................”

Yeah it will be real bad. Escape routes pre blow if there is a warning is North or South, maybe East if 50 miles out is considered safe? (Aberdeen / Olympic Peninsula) When it goes basically only North is an escape route for those that live in Tacoma and North of = Seattle.

Highway 5 will a cluster cluck heading towards Canada, a killing field. Clean up will be next to impossible and will cause civil unrest when there isn’t enough 1st Responders and money to clean up and bury the dead. (if even found)

His response is right out of the USGS description

Like they are such expert at predicting volcanic eruptions by Super Volcanoes .. gotta keep the public pacific and relaxed, can’t have panic.

Wiping out Seattle with molten rock wouldn’t be the worst outcome contemplated. You could leave with a car and be good

Exactly what I was thinking, so I laughed.

Viral ‘eruption threat’ at ‘America’s deadliest volcano’ Mount Rainier not accurate, PNSN says

That is very true. I was thinking of the scenarios involving lahar flows that evidence shows happened in the past. You are correct though, if it explodes, that is a very different ball of wax.

In that case, it would very likely be the worst humanitarian disaster in recorded history, given the population density, and the likely catastrophic affects of an explosion of a Supervolcano like that.

If Mount Rainier goes, it will probably just kill Seattle and the suburbs.

So you are saying no Americans would be harmed. Great!
