How a Fjord in Greenland Triggered a Global Seismic Signal

A massive chunk of ice fell off a glacier in Greenland, causing a magnitude 4.0 earthquake that was felt around the world.

The calving event, which occurred on 12 September 2024, sent a seismic signal that was recorded by sensors around the globe.

The signal was so large that it was even picked up by the US Geological Survey's (USGS) National Earthquake Information Center (NEIC) in Golden, Colorado.

The USGS reported that the earthquake had a magnitude of 4.0 and was located about 100 kilometers west of Upernavik, Greenland.

The earthquake was caused by a large chunk of ice falling off the Jakobshavn Glacier, one of the largest and fastest-moving glaciers in Greenland.

The ice chunk was about 1 kilometer wide and 100 meters thick, and it weighed about 1 billion tons.

When the ice chunk fell into the ocean, it created a large splash that generated a seismic wave.

The seismic wave traveled through the Earth's crust and was recorded by sensors around the world.

The seismic signal was so large that it was even picked up by the NEIC in Golden, Colorado.

The NEIC reported that the earthquake had a magnitude of 4.0 and was located about 100 kilometers west of Upernavik, Greenland.

The earthquake is a reminder of the power of nature and the potential for earthquakes to occur in unexpected places.

It is also a reminder of the importance of monitoring glaciers and other natural hazards to help mitigate their impact on human populations.
