Last year, I posted about an incredible event in 2023: a megatsunami in Greenland triggering an initially baffling 9-day seismic pulse across the whole planet & a terrific piece of collaborative international scientific detective-work.
Now there's a sequel.
And holy hell, it's even BIGGER.

OK, this is wild.
In September 2023, geophysicists across the world started monitoring a very odd signal coming from the ground under them.
It was picked up in the Arctic. And Antarctica. It was detected everywhere, every 90 seconds, as regular as a metronome, for *nine days*.
What the HELL?

Earth is a strange, and extreme place. In September 23, 2023 there was a collapse of 25 million tons of ice in east Greenland fjord. It resulted in a local megatsunami with waves 100-200 m high, which oscillated inside the fjord for 9 days!

The result, as with the 2023 Dickson fjord event, was a runup megatsunami.
But this one was far taller. It reared an astounding 481 METRES, the second highest ever recorded.
That's difficult to imagine, so - you know what's a full 150 metres shorter than that?

In fact, a "megatsunami" event occurred just 2 yrs ago, in 2023, when a massive rockslide caused a ~650 foot wave in a Greenland fjord. The resulting oscillation literally "rang the Earth" like a bell for 9 days! (The paper describing this is remarkable):

Climate change is increasingly predisposing polar regions to large landslides. Tsunamigenic landslides have occurred recently in Greenland (Kalaallit Nunaat), but none have been reported from the eastern fjords. In September 2023, we detected the start ...
