In Greenland, the Ice Doesn’t Just Flow, It Quivers and Quakes

When Andreas Fichtner unspooled a fiber-optic cable into a deep hole in Greenland’s ice, he discovered new insights into how glaciers move, picking up “ice quakes” reverberating deep within the ice. This challenges the traditional view of ice flow as smooth and uniform, suggesting that ice actually moves in a more complex, seismic manner. While this discovery sheds light on ice physics, its implications for predicting sea level rise and understanding ice sheet behavior remain uncertain, with further research needed to fully grasp the impact of these findings.
