The East Greenland region, particularly around Dickson Fjord and Karrat Fjord, is subject to significant geological activity influenced by climate change. Seismic signals recorded here indicate the occurrence of destructive landslides and rock-ice avalanches. These seismic events can generate mega-tsunamis, which pose a threat to coastal communities.
Seismologists utilize computer simulations and numerical modeling to analyze seismic waves and tremors from various events. The Geological Survey of Denmark and Greenland conducts ongoing research to monitor these phenomena. Satellite imagery and geophysical observations enable scientists to assess changes in glaciers and permafrost, contributing valuable data to the seismic record.
Recent studies also explore the impact of standing waves and seiches in fjords, which can intensify the effects of seismic activity. Insights gained from satellite images reveal alterations in the landscape that may enhance the risk of landslides. Earth scientists focus on the intricate interactions within Earth’s crust as climate changes reshape these polar regions.
Monitoring and understanding these geological dynamics is crucial. It allows for better preparedness against potential disasters like rockslides, which can lead to extensive ecological and human impacts in this fragile environment.
