While I think it’s exaggerated, the concerns are valid. If something like what hit Alaska in the ‘60s hits a more densely populated are there will be damage and things will be off line for a while. But also it’s not a catastrophic event that wipes out the economy of the area.

Of course that’s of no comfort to the people who will perish n such an event.

It’s just that it’s not going to be like a 1920s Tokyo or SF 1906 since we should have better handle on fire and emergency response in general.
