According to reports, researchers at the GFZ German Research Center for Geoscience identified two distinct seismic signals from the event. The first signal was a high-energy signal caused by the initial rock slide that generated the tsunami. After this there was a long wave which continued for more than a week.
Long wave signals were received up to a distance of 5 thousand kilometers. Waves were seen for several days on the shores of Dixon Fjord. The special thing is that the common people came to know about this great tsunami before the scientists. People had shared posts on social media.
Researchers traced the route of the landslide using satellite imagery and seismic data. It was found that the landslide also involved glacier ice, which mixed with the rock and caused a landslide in the area.
The landslide caused a huge tsunami. Its entry point was more than 200 meters high. In the area of Dixon Fjord it was 60 meters high. However, there was no loss of life or property. Researchers say that it is exciting that the signal of the wave caused by the sliding of a rock in a remote area of Greenland is found worldwide and persists for more than a week.
