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.................
Yep, "normalcy bias" at work. "It hasn't happened so it cannot happen to me." Until BOOM!
Because of that huge ice and snow cap, it doesn't look like people in eastern WA or north ID are at risk. The "lahar" will be big when all that ice and snow melts almost instantly.

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)
