Oh, yes. The last big lahar, occuring on the northern face of the mountain, created the Green River Valley which is now heavily populated.

It's less likely than, say, a lahar on the southern side. Something about the quality of the rock on the northern face. It's more likely it would go the other direction and wipe out Puyallup.

I did play "stump the insurance company" when I called USAA to ask if they considered a lahar to be "volcano" or "flood". They had to call me back. Tee hee!

I guess freak catastrophes do happen, like NO and the Tsunami, then you have Iceland - it has so much volcanic activity, it's physical map has to be changed every few years (think Surtsey Island)!

BTW, they are doing a lot of worrying about the geological activity under Yellowstone Park - what do ye make of it?
