Researchers have discovered numerous tiny ice quakes occurring deep within Greenland’s ice streams. These quakes contribute to the movement of ice streams, which, contrary to previous assumptions of flowing like viscous honey, also exhibit a continuous stick-slip motion. The team recorded seismic activity using a fiber-optic cable installed in a 2,700-meter-deep borehole inside the ice [...]from SciTechDaily https://ift.tt/YldRGfa
