Greenland Tsunami Shakes Earth for Nine Days: A Climate Crisis Revelation
In September 2023, a seismic event of unprecedented scale shook the planet, all thanks to a colossal landslide in Greenland. This landslide, which occurred in the remote Dickson Fjord, triggered a mega-tsunami that would send shockwaves reverberating through the Earth’s crust for an astonishing nine days. The event not only puzzled scientists but also underscored the profound effects of climate change on our planet.
The drama began on September 16, 2023, when a massive piece of a glacier-supported mountain in Greenland gave way. As the glacier thinned due to rising temperatures, it could no longer support the overlying rock. The result was a staggering landslide: a mountain of rock and ice, estimated to be equivalent to 25 Empire State Buildings, plunged into the fjord. This catastrophic event unleashed a towering tsunami wave, reaching heights of 200 meters.
The fjord’s unique geography played a crucial role in amplifying the impact. The narrow and winding Dickson Fjord effectively trapped the tsunami wave, causing it to slosh back and forth. This phenomenon, known as a seiche, continued for nine days, creating a persistent and unusual seismic signal that was detected by monitoring stations worldwide.

The initial discovery of the seismic anomaly left scientists baffled. It didn’t resemble the typical patterns of earthquakes. Instead, it was a consistent, rhythmic signal, which led researchers to dub it an "Unidentified Seismic Object" (USO). With no precedent for such an event, the global scientific community rallied to decipher the cause.
An international team of about 70 scientists from 15 countries undertook a rigorous investigation. They combined seismic data, satellite imagery, and field reports from the Danish Navy to piece together the puzzle. The investigation revealed that the landslide caused a mega-tsunami, which then created a seiche within the fjord, generating the prolonged seismic waves.
The destruction was significant. The mega-tsunami not only caused damage within the fjord but also impacted nearby areas. The waves reached as far as 13 feet high, affecting unoccupied research stations and archaeological sites. Remarkably, no ships or human lives were lost, largely due to fortunate timing and the remote location of the event.
This unprecedented event highlights the growing threat of climate change. As global temperatures rise, glaciers and ice masses are melting at accelerated rates, leading to instability in mountain regions. The Greenland landslide is a stark example of how climate-induced changes are now triggering natural disasters of epic proportions.
Dr. Kristian Svennevig, one of the leading researchers, emphasized the broader implications of this event. “This is the first time we’ve seen such a massive, long-lasting seismic event triggered by climate change. It underscores the urgent need to understand and mitigate the impacts of global warming.”
In summary, the nine-day rumble that echoed around the world from Greenland’s Dickson Fjord serves as a dramatic reminder of the interconnectedness of our planet's systems. It’s a potent symbol of how climate change is not just an environmental issue but a global phenomenon with far-reaching impacts. As scientists continue to study this extraordinary event, it’s clear that the ripple effects of climate change are more profound and far-reaching than ever imagined.
