Tectonics on Jupiter's moon Europa

Sep 11, 2014

What would you call an earthquake on Europa?  In many ways Jupiter’s moon is like Earth, with tectonic plates shuffling across its face, creating new surface where it parts and subducting older surface to the liquid below, but where Earth uses rocky crust and lava, Europa uses salty seas and a crust of ice.

This communication between exterior and interior lends hope to the idea that panspermia has taken root and the subsurface sea is inhabited.
