Entire #Earth was Mysteriously Shaking Every 90 Seconds. Now, Scientists Know Why
For 9 days in Sept 2023, world was rocked by an “Unidentified Seismic Object.”
#Scientists have now confirmed that this literally Earth-shaking event was caused by two mega-#tsunamis in #DicksonFjord, a narrow inlet in East #Greenland, which were triggered by the effects of human-driven #climatechange according to a study published on Tuesday in Nature Communications.

Bizarre, nine-day #seismic signal caused by epic #landslide in #Greenland
The source of the signal was eventually traced back to a massive landslide in Greenland’s remote #DicksonFjord. A staggering volume of rock and ice, enough to fill 10,000 Olympic-sized swimming pools, plunged into the #fjord, triggering a 200-meter-high mega-tsunami and a phenomenon known as a #seiche: a wave in the icy fjord that continued to slosh back and forth, some 10,000 times over nine days.

Holy crap, did you even know this happened?
Last September, a 1,200-meter-high mountain peak collapsed in Greenland after the glacier supporting it from below melted. The resulting landslide triggered a 200-meter high tsunami that sent shockwaves reverberating across the planet for over a week (earthquakes only last minutes to hours by comparison). #tsunami #DicksonFjord

200 Meter hoher Tsunami:
„Es war ein gigantisches geologisches Ereignis,dessen seismisches Signal Erdebenmessstationen rund um den Globus registrierten. Besonders auffällig waren lang anhaltende Schwingungen,die vom Hin-& Herschwappen des Wassers im engen Fjord verursacht wurden.“ via #SZ #Bergsturz #DicksonFjord #Grönland

It started with a melting #glacier that set off a huge landslide, which triggered a 650-foot high mega-tsunami in #Greenland last September. Then came something inexplicable: a mysterious vibration that shook the planet for nine days.

Over the past year, dozens of scientists across the world have been trying to figure out what this signal was
