In a recently video from Ilimanaq, Greenland, the breathtaking moment a giant iceberg cracked and plummeted into the freezing sea was captured on camera.

The massive impact triggered a spectacular splash, generating a “massive wave”—or so that’s what they called it—that surged outward from the ice face.

Take a look and judge for yourself.

While it is certainly not the biggest wave we’ve seen from falling ice—last year, a landslide of rock and ice in Greenland’s Dickson Fjord famously triggered a 650-foot mega-tsunami—this recent calving footage remains an awe-inspiring reminder of nature’s raw power.

This dramatic phenomenon is known as glacier calving. It occurs when massive chunks of ice break away from the edge of a glacier during the summer melt and crash into the water below. The sudden displacement of thousands of tons of ice creates localized, unpredictable surges often referred to as glacier tsunamis.

For a fringe group of extreme surfers, these erratic waves are the ultimate prize.…
