Greenland's 650-Foot Mega-Tsunami Shook Earth For 9 Days, Satellite Data Confirms. Tuesday June 3, 2025; Science | Edited by Nikhil Pandey; A massive landslide in Greenland's Dickson Fjord in 2023 ...

A series of "extraordinary" tremors observed across the globe were caused by two tsunamis stranded within a fjord in ...

The Dickson Fjord, about 1.7 miles (2.7 kilometers) wide and 1,772 feet (540 meters) deep, lies along a remote network of channels on Greenland’s rugged east coast.

The Earth was trembling every 90 seconds. Now, we know why.

A landslide in Greenland's Dickson Fjord triggered a 650-foot mega-tsunami in September 2023. The event caused the Earth to vibrate every 90 seconds for nine days, puzzling scientists initially.

In 2023, scientists were baffled by a bizarre seismic signal that repeated every 90 seconds for nine days. Now, a study has confirmed the root cause of this phenomenon.

Dickson Fjord’s narrow, cavity-like geography—measuring about 1.7 miles (2.7 km) wide and 1,772 ft (540 m) deep, with walls soaring over 6,000 ft (1,830 m) acted like a natural resonance chamber.

The study went on to note that a cause for the pulse could have been that it was struck by a small piece of space rock, known ...

While scientists were baffled at first but the source was later traced to the remote Dickson Fjord in East Greenland – a narrow inlet that is bordered by 3,000-feet high cliffs.

The signals began after a landslide triggered by a megatsunami in Dickson Fjord, Greenland, and was thought to have been produced by a seiche, or standing wave.
