Massive Greenland Landslide Shook Earth for Nine Days
Greenland Landslide Triggered by Calving Glacier
A colossal landslide in Greenland in 2017 sent seismic waves around the globe for nine days, according to a new study. The landslide, triggered by the calving of a glacier, was so powerful that it caused the Earth to wobble slightly on its axis.
The study, published in the journal Nature Geoscience, found that the landslide was the largest ever recorded in Greenland. It released more than 1 trillion tons of ice and rock into the ocean, creating a tsunami that reached heights of up to 100 feet.
Landslide Caused by Glacier Calving
The landslide was triggered by the calving of the Jakobshavn Isbrae glacier, one of the largest and fastest-moving glaciers in Greenland. Calving occurs when a glacier breaks off into smaller pieces, which can then fall into the ocean.
In this case, calving triggered a massive block of ice and rock to break off the glacier and fall into the ocean. The impact of the falling ice and rock generated a powerful seismic wave that traveled around the globe.
Seismic Waves Traveled Around the Globe
The seismic waves from the landslide were so powerful that they were detected by seismometers around the world. The waves traveled through the Earth's crust and mantle, causing the Earth to wobble slightly on its axis.
The study's authors said that the landslide is a reminder of the potential for large-scale landslides in Greenland. These landslides can have a significant impact on the global climate, as they can release large amounts of freshwater into the ocean.
Conclusion
The Greenland landslide is a reminder of the power of nature. It is also a reminder of the importance of studying these events, so that we can better understand the risks they pose to our planet.
