The earthquake distribution on ultra-slow mid-ocean ridges differs fundamentally from other spreading zones. Water circulating at a depth of up to 15 kilometers leads to the formation of rock that resembles soft soap. This is how the continental plates on ultra-slow mid-ocean ridges may move without jerking, while the same process in other regions leads to many minor earthquakes, according to geophysicists.
