Triggered by a landslide in a Greenland fjord, a tsunami shook the Earth for nine days in September 2023, an international team of researchers reported in the journal Science. The phenomenon was caused by global warming and could be set to happen again.
When global warming causes a landslide, which itself causes a huge tsunami. An international team of researchers revealed in the journal “Science” that this phenomenon took place in September 2023, when a landslide in a Greenland fjord caused the Earth to vibrate for nine days.
“What is quite unique about this event is the duration of the seismic signal and the constancy of its frequency,” one of the study’s authors, Kristian Svennevig of the Geological Survey of Denmark and Greenland (GEUS), told AFP on Friday.
“Other landslides and tsunamis have produced seismic signals, but only for a few hours and very locally. This one has been observed worldwide, all the way to Antarctica,” he added.
