One suggestion included the back-and-forth rubbing of opposing walls of the fractures generating frictional heat that turned ice into geyser-forming vapor and liquid.

“These electrostatic forces increase frictional thresholds,” said Josh Mendez Harper, a Georgia Tech geophysics and electrical engineering doctoral student who is the paper’s lead author.

Individual geysers were found to coincide with small-scale hot spots, only a few dozen feet (or tens of meters) across, which were too small to be produced by frictional heating, but the right size to be the result of condensation of vapor on the near-surface walls of the fractures.
