Lavaflow maps?

Question

Does maps of underground lavaflows exist?
If so - can I find them online?
I´m mostly interested in flows in and around Mexico.

Answer 1

I have looked on every site there are for underground lava flows, There are only surface lava flows however, here is a diagram how magma works.

I have tried to find a site for underground lava flows for about 3 days and still found nothing.

http://www.tulane.edu/~sanelson/geol204/volhaz&pred.htm you may find this interesing though. I do not think there are any underground Magma flow maps, every diagram I see is like a saggittal view of the inner earth (like the magma diagram in your first link)
