[Geology2] Re: Volcano News April 14, 2013

Lin,

I like the credit, but I didn't send the heads-up on this.

I just joined Geology2 this week. Thought it was about time. I don't
know much about geology, but I know a rock when I see one. (I just
thought that up, so don't tell me if you've heard it before.)
