I just recently heard of that a very large pool of magma sits
beneath Mammonth Lake , California. If an eruption occured here what
would be the result, in your opinion? I have heard that a volcanic
eruption at this location could result in a major catastrophe that
would envelop the world.

Hi Matt,
Well, there may or may not be a huge pool of magma down there. Certainly the
fact that there is a huge caldera in the area (Long Valley caldera), and the
fact that there are extensive ash deposits extending away from the
caldera for hundreds of kilometers, tells you that in the past there have
been huge eruptions from presumably huge magma chambers. I think the
jury is still out regarding the present situation, however. If you want
to learn more, from folks who are really studying the area, check out the
Long Valley home page here.
Good luck on your quest.
