Today’s Video of the Day from the USGS describes a rift that is expanding across the Petermann Glacier in northwestern Greenland.
It is not unusual for large icebergs to break away from the Petermann Glacier, which recently occurred in both 2010 and 2012.
After a new rift was spotted on the glacier in 2017, images captured by the Landsat and Europe’s Copernicus Sentinel-2 satellites have shown that the rift is getting longer and meeting up with and older crack.
At the current rate, the potential iceberg could exceed 150 square kilometers in size.
