What I have always wanted to know, from your map, is the AMOUNT, in cm or inches the ash fall would be, AND, what we could do to mitigate that disaster here in Arkansas?

When my wife and I bought our new house, we insisted on a steep pitch, steel roof, with 12, NOT 16", space roof. We could take a few FEET of heavy, wet snow, and our roof would survive. I don't know what wet pummice weighs, but I bet it is an order of magnitude higher.

IIRC most deaths and damage when Mt. Penitubo blew was from collapsed roofs (most of which were not steep enough pitch) to allow ash to fall off.

Well, crap. We’re in NW AR in a 110 yr old house. Maybe the first floor won’t get crushed.
