Huge landslide unleashes 650-foot ‘mega-tsunami’ and causes Earth to vibrate for 9 DAYS

After a mountaintop collapsed into the sea in Greenland, a ‘mega-tsunami’ as tall as a skyscraper shook the Earth for nine straight days, baffling scientists around the world.

No one was injured by the landslide or resulting tsunami, but the 650-foot-tall wave destroyed roughly $200,000 worth of infrastructure at an unoccupied research station on Ella Island.

Before and after the mᴀssive landslide that dumped 33 million cubic yards of ice and rock into a Greenland fjord, triggering a 650-foot-tall 'mega-tsunami' that shook Earth for nine days

What’s more, the events occurred near a route that is commonly traveled by cruise ships. Had one been sailing through at this time, it could have led to tragedy.

Until now, no one knew what caused the mysterious seismic activity that began in September 2023 and lasted over a week. It took an international team of scientists to trace it back to the landslide.

‘When we set out on this scientific adventure, everybody was puzzled and no one had the faintest idea what caused this signal,’ said Kristian Svennevig, study lead author and geologist at the Geological Survey of Denmark and Greenland.

Climate change set the stage for this landslide by melting a glacier at the base of the mountain and destabilizing enough ice and rock to fill 10,000 Olympic swimming pools

Svennevig and her colleagues now believe that climate change set the stage for this landslide by melting a glacier at the base of the mountain and destabilizing enough ice and rock to fill 10,000 Olympic swimming pools.

And as rising global temperatures continue to melt Earth’s polar regions, destructive landslides like this one could become more common.

The research team published their findings today in the journal Science.

When seismic monitoring networks first detected the activity, scientists were perplexed for two reasons.

The mega-tsunami destroyed roughly 0,000 worth of infrastructure at an unoccupied research station on Ella Island, but no one was hurt

First, the signal was much more spread out than the typical тιԍнт squiggles that an earthquake produces on a seismograph – a device used to record ground shaking.

‘It oscillated with a 92-second-interval between its peaks, too slow for humans to perceive,’ according to a statement from the University of California San Diego, one of the insтιтutions that contributed to the research.

Second, the signal remained strong for nine straight days. Typical seismic events decay much more rapidly – the average earthquake lasts only seconds to minutes.

Scientists around the world quickly began working to get to the bottom of this strange signal.
