The video captures a 4.5 million section of ice breaking off of Greenland’s Helmheim Glacier that occurred at the end of June. The scariest part, the total time eclipsed was only 30 minutes.
Researchers managed to catch it on camera, and they’ve released a sped-up video that condenses the violence of the ice-shattering event into a little over 90 seconds.
The Helheim glacier dips into the ocean in eastern Greenland, and the first ice chunk to break off was wide and shallow, “like a pancake,” says David Holland, an NYU professor who led the expedition to Greenland
In the end section of the glacier as big as lower and midtown Manhattan combined broke apart and floated into the ocean, according to the researchers.
