Over 25 million cubic yards of rock and ice broke loose and plunged into Greenland's Dickson Fjord, creating a 650-foot-high mega-tsunami ...

Sensitive scientific instruments, so-called seismometers, can be used to record vibrations that ring the Earth. The instruments usually measure the seismic waves, which are generated during ...

In a remote corner of East Greenland, a section of mountain gave way, collapsing into a narrow glacial fjord bounded by steep cliffs and long untouched by significant disturbance. The resulting impact ...

After seismologists detected abnormal vibrations, they determined that a 650-foot tsunami had occurred in Greenland. The tsunami was the result of melting glacial ice, which caused a landslide that ...

Data on a fjord in the country revealed extreme sloshing in the channel, caused by a rockslide felt around the world. Reading time 2 minutes A satellite flying over Greenland last year captured an ...

In the spring of 2024, a group of scientists attending a national seismology conference in Anchorage purposely sailed into danger. Chartering a tour boat, they sailed into Prince William Sound and ...

When a slab of rock crashed into a remote Greenland fjord, it did more than send water racing up the valley walls. The collapse triggered a 650-foot mega-tsunami that set the entire planet ringing ...

Tour boat operators and cruise ship captains face a growing hazard: tsunamis generated by collapsing cliffs. If disaster strikes, what should they do? By Christian Elliott / Hakai Magazine Published ...

In 2015, 76 million cubic meters of rock crashed from the rugged cliffs above a southeastern Alaska fjord and into the water below. The landslide sparked a nearly 200-meter-tall wave that roared down ...

Landslide-generated tsunamis don't come with any warning signs and they're impossible to predict. Tsunami scientists are meeting with vessel operators in Alaska this month to put together some ...

Move over earthquakes, tsunamis have taken center stage. I will acknowledge the largest magnitude earthquake since 2011, but the Kamchatka M8.8 did little shaking damage and the tsunami was the bigger ...
