We had a thread about this several months ago, but I'll bet few remember it. Recently the people living near Mt. Pinatubo were in gread danger. Do you know why?

Here is a URL on the general subject.http://www.geo.mtu.edu/volcanoes/pinatubo/lahar

Hi, Dr. Bill,

I hope you're having a good birthday today! I remember the lahar thread--CapK gave a good explanation of what it is. But I don't know about recent danger from Mt.
Pinatubo--I've gone back to my habit of not watching TV.
