A Greenland iceberg collapsed on June 6, sending a huge wave through a fjord near Ilulissat, startling tourists and drawing wide attention after footage spread online.
The video, filmed by tour operator Diskoline Explorer, showed a large section of ice breaking away from a glacier and crashing into the water. The impact sent a surge across the fjord.
Diskoline Explorer described it as “maybe the biggest one” seen on one of its Icefjord cruises. The operator said the crew turned the boat toward the wave and told passengers to hold on.
The company said there was no danger to passengers. Its account said crews follow this approach when large waves form after glacier calving events.

Glacier calving occurs when large chunks of ice break away from a glacier. In Greenland, such events can send powerful waves through fjords and pose risks to small vessels.
The collapse added to public attention on Greenland’s changing ice landscape. Scientists monitor the Greenland ice sheet as Arctic ice loss accelerates and reshapes polar environments.
