In a first, researchers have recorded countless "ice quakes" that sporadically shake the Greenland Ice Sheet. These quakes may explain the jerky way that the island's frozen rivers move downstream ...

Scientists discovered thousands of ice quakes beneath Greenland’s Ice Sheet, changing our understanding of ice movements and global climate. These quakes, revealed through advanced technology ...

While scientists once thought Greenland’s ice streams flowed slowly and uniformly, new research reveals a quake-driven “stick-slip” motion that’s linked to volcanic activity thousands of ...

In Greenland, an international team of researchers led by ETH Zurich has discovered that countless tiny ice quakes take place deep inside ice streams. • These quakes are responsible for the fact ...

Seismic surface waves radiating away from the earthquake’s epicenter traveled some 4,700 kilometers before passing through Antarctica’s ice sheets and causing small tremors, or “icequakes.” ...

Researchers recorded ice quakes in the Greenland Ice Sheet by lowering a fiber-optic cable down a borehole. Pictured above is a tunnel that leads to the borehole. | Credit: Andreas Fichtner/ETH ...

Quakes recorded for the first time inside Greenland's biggest frozen river, the Northeast Greenland Ice Stream, suggest this river and others switch between moving jerkily and flowing like honey.
