Just throw some water and essentials in the car and drive in the other direction and don't insulate your car. 4 m/s is like 15 km/h - you can out drive it easily.
Somewhat important to note that if everyone does this it will likely overwhelm the roads and end up in gridlock
Yeah that’s what I was thinking, in which case what do you build to maximize survival in the mean time? Floating fluffy pods or something
a bicycle. throw a bicycle in a bike rack on your car. when you hit gridlock, bike further out.
> 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?

Not in the last 1000 years, no, but - they do mention they think there have been 11 Lahar events originating from Ranier that have impacted the seattle area, over the past 6000 years - one of which doesn’t even seem to be associated with a volcanic eruption.
At first I was like “why worry about Ranier when Hood is active” but - yeah the mother of all flash-floods is a horrifying prospect.

Different volcano, but back in the 50's the natural tephra damn on the crater lake of Mount Ruapehu (New Zealand) collapsed triggering a lahar, that ultimately took out the piers of rail bridge near Tangiwai minutes before a passenger train tragically attempted to cross the bridge, resulting in mass casualty's.
So certainly possible for non-expulsive activities to trigger a lahar and for consequences that sound like they are more from a disaster movie then real life to occur.

I don't think so, as they have separate magma chambers AFAICT, although Mt St Helens does look like it shares its magma chamber with other nearby volcanoes.
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.
Not sure what I would do. Wrap my car with metal, and hope for the best?
