Shear heating as the origin of the plumes and heat flux on Enceladus
Article Abstract:
The heat and vapor production is due to shear heating by tidally driven lateral (strike-slip) fault motion, where the vapor escapes as plumes through cracks reopened by tidal stresses. The analysis shows that tiger stripe regions with highest relative temperatures will be the lower-latitude branches of Damascus.

Eruptions arising from tidally controlled periodic openings of rifts on Enceladus
Article Abstract:
A mechanism is described in which the temporal variations in tidal stress open and close the tiger-stripe rifts, thus governing the timing of eruptions. The stresses controlling the eruptions have suggested that Enceladus' icy shell behaves as a thin elastic layer, which are only a few tens of kilometers thick.

Cracks under stress
Article Abstract:
Researchers have demonstrated that heating from shearing motion along the parallel cracks (tiger stripes), provides energy for the venting activity. They have also considered how forces across the stripes might help in opening and shutting the cryovolcanic vents.
