A tsunami struck a fjord in East Greenland in 2023, ringing seismometers for nine straight days. A new satellite study ...

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.

As fascinating as bizarre signals from other planets can be—teaching us about earthquakes on Mars or auroras in the skies of Jupiter —sometimes even weirder signals come from weather extremes ...

In September 2023, a massive landslide in Greenland's Dickson Fjord triggered a mega-tsunami, sending seismic waves globally for nine days. The 650-foot wave, caused by climate change-induced ...

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.

In September 2023, Greenland’s Dickson Fjord experienced a colossal landslide that triggered a 650-foot mega-tsunami, causing the Earth to pulse with rhythmic seismic signals every 90 seconds ...

These avalanches thundered into Dickson Fjord, displacing enormous volumes of water and generating tsunami-like waves with an initial height of up to 7.9 meters.

The tsunami unleashed in Dickson Fjord had enough strength to leave powerful winds and sudden atmospheric pressure shifts in its wake, pushing water from one end of the enclosure to the other.

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 findings were published Tuesday (June 3) in the journal Nature Communications. The fjord’s unique geography trapped the tsunami’s energy, preventing it from dissipating quickly.

Mega-wave reshapes Dickson Fjord On 16 September 2023, millions of tonnes of rock fell. The impact hurled up a wave 650 feet high. It raced down the fjord, smashed into cliffs, then reversed.
