Moon May Be Geologically Active
dptalia writes, "For decades scientist have thought that the moon has been 'dead' for about 1 to 3 billion years. However, new research points to the idea that the moon may have been volcanically active as recently as 1 million years ago. In fact, NASA geophysicist Paul Lowman believes the moon's core is still molten."
If I remember correctly, moon quakes are the result of tidal forces between the earth and the moon... not geologic activity.
