Mega-Tsunami in Greenland Triggers Global Seismic Waves
A massive landslide in Dickson Fjord, Greenland, has triggered a 650-foot mega-tsunami, sending seismic waves detectable around the world for nine days. The event occurred on September 16, 2023, when over 25 million cubic yards of rock and ice plunged into the fjord, creating a wave that devastated equipment at a nearby research post. The tsunami's impact was so powerful that it caused a seiche, a standing wave in the fjord, which continued to generate seismic signals detectable globally. This phenomenon was captured by satellite imagery and analyzed by an international team of scientists, who used computer models to understand the event's dynamics.
