Oxford University Confirms Greenland Tsunami Caused Global Seismic Signals

In September 2023, and again in October, unusual seismic signals were detected worldwide, lasting for several days. Researchers from Oxford University have now linked these signals to a mega-tsunami in Greenland's Dickson Fjord. This tsunami, caused by a landslide, generated a 200-meter-high wave that caused the fjord's water to oscillate, creating a phenomenon known as a 'seiche.' Scientists used data from the Surface Water Ocean Topography (SWOT) satellite to study the event. The satellite's advanced technology allowed them to map changes in water elevation, confirming the tsunami's impact and its connection to climate-driven events in remote regions. The landslides were caused by the melting of a glacier due to climate change. The findings highlight the increasing frequency of extreme events linked to climate change.
