    I'm afraid, too. The Moon was still geologically active just 800 million years ago (no so much time from a geological point of view). You can find usefull informations at: http://www.skyatnightmagazine.com/feature/column-excerpts/our-volcanic-moon Voyager I observed volcano activity in 1979 on Io, the moon of Jupiter.
