German scientists from the University of Potsdam have discovered the cause of the giant tsunami that hit the east coast of Greenland about a year ago. A 200-meter-high wave then entered the deserted Dikson Fjord, destroying abandoned buildings. The research was published in the scientific journal magazine Sound Recordings (TSR).
The team analyzed seismic data from earthquake monitoring stations located within a 5,000-kilometer radius of the scene. Experts discovered signals that persisted for a long time after the underwater landslide caused a massive wave.
Using satellite imagery and computer modeling, researchers confirmed the existence of a standing wave about one meter high that lasted more than a week.
Scientists believe the phenomenon is caused by the ongoing melting of glaciers and permafrost in Greenland, a process that increases the likelihood of new landslides and subsequent megatsunamis.
Smaller-scale events have been observed several times off the coast of Greenland in recent years. For example, in 2017, a rockfall on the west of the island caused a tsunami that flooded the village of Nuugaaisiak. The disaster destroyed 11 homes and killed four people.
Earlier scientists I learned the reason for the appearance of monster waves tens of meters high in the open sea.
