According to reports, researchers from the GFZ German Research Centre for Geosciences 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. This was followed by a long wave that lasted for more than a week.
Signals of long waves were received up to 5 thousand kilometers away. Waves were seen on the shores of Dixon Fjord for several days. The special thing is that common people came to know about this great tsunami before scientists did. People shared posts on social media.
Researchers used satellite imagery and seismic data to trace the landslide’s route. It turned out that the landslide also involved glacier ice, which mixed with rock and caused landslides in the area.
The landslide caused a very large tsunami. Its entry point was more than 200 meters high. In the area of Dikson Fjord, it was 60 meters high. However, there was no loss of life or property. Researchers say that it is exciting that the signals of the wave generated by the sliding of the rocks in a remote area of Greenland were received all over the world and remained for more than a week.
