Greenland icebergs create powerful earthquakes recorded around the world when they break off

When large icebergs break off, they produce a seismic event detectable across the Earth.

These glacial quakes are all around magnitude 4.6 to 5.2. So pretty big.

These earthquakes aren’t caused by faults but triggered by incredible movements of ice and how those impact the ground beneath.

Glacial earthquakes are induced during iceberg capsizing:

In comparison to the early 1990s, these glacial earthquakes have increased by seven. Yes, that’s another way to prove that global warming is there!

As cited by the Washington Post:

One of the most impressive and apocalyptic calving was filmed in 2008.
