Greenland Mega Tsunami
The world was shaking!
- On September 16, 2023, scientists recorded a seismic event so strange that they named it a USO (unidentified seismic object).
- Seismic data collected around the world (along with satellite imaging) confirmed that the event—which vibrated around the world for a staggering nine days—was caused by a rockslide that triggered a mega tsunami and an undulating seiche (a type of sloshing wave).
- This event was likely caused by the thinning of a glacier due to climate change, and researchers expect more events like it to occur as the world warms.

The cause was alarming—and it will likely happen again.
