A rare deep-Earth tremor has been detected for the first time on the ocean floor in Japan.
Using seismic equipment, researchers have managed to trace its location to a distant and powerful storm between Greenland and Iceland.
The findings could help experts learn more about the Earth's inner structure and improve the detection of earthquakes and oceanic storms.
The storm that caused the deep-Earth tremor was a 'weather bomb' that struck over the North Atlantic.
This is a small but potent storm in which pressure quickly builds, creating a more vigorous storm.
As the storm hit, groups of waves pounded the ocean floor between Greenland and Iceland.
