🌊 *Alerta en los fiordos: un #megatsunami de 481 metros en #Alaska revela un riesgo letal para los cruceros turísticos.* Los científicos avisan de que fue una cuestión de suerte que tras la avalancha de agosto de 2025 no ocurriera una tragedia. El suceso, que han analizado con todo detalle, se debe en buena parte al #cambioclimático

"Massive Alaska megatsunami was second largest ever recorded
A massive 'megatsunami' wave created when part of an Alaskan mountain crumbled into the sea is the second tallest ever recorded – and a reminder of the risks posed by melting glaciers, say scientists.
Last summer a giant wave swept through a remote fjord in southeast Alaska leaving destruction in its wake.The event went largely unreported at the time, but a new scientific analysis shows it was caused by a massive landslide.
An incredible 64 million cubic metres of rock – the equivalent of 24 Great Pyramids - splashed into the water below. The sheer power of that amount of rock plunging into the fjord in under a minute created a gigantic wave almost 500 metres tall.
Only the time it happened – in the early hours of the morning – prevented tourist cruise ships being caught up in the devastation, say the researchers." -

There was a megatsunami in Lituya Bay in 1958, https://en.m.wikipedia.org/wiki/1958_Lituya_Bay_earthquake_and_megatsunami . An earthquake caused a massive rockfall into a bay. The impact with the water generated a massive wave with a run up of 520m on the opposing slope. It was a shockingly powerful wave!
It turns out this kind of event is a risk in high latitude mountainous coastlines. The glaciers create steep valleys with fjords. The steep slopes have a high rockfall risk. In Norway, they are doing a mapping program to give warning before such disasters https://www.earthmagazine.org/article/comment-assessing-threat-massive-rock-slope-failures-norwegian-fjordlands

#ClimateChange triggered 2023 mega-landslide caused Earth to vibrate for nine days
Date: September 12, 2024
Source: University College LondonSummary:
"A landslide in a remote part of Greenland caused a 200 meter (650 foot) #megatsunami that sloshed back and forth across a #fjord for nine days, generating vibrations throughout Earth, according to a new study. The study concluded that this movement of water was the cause of a mysterious, global seismic signal that lasted for nine days and puzzled seismologists in September 2023."https://www.sciencedaily.com/releases/2024/09/240912142355.htm

"#Tsunami: #Asteroid #Impact - 66 Million Years Ago"
"The 6+ miles wide asteroid that hit Earth 66 million years ago, .. have wiped out nearly all the #dinosaurs + roughly three-quarters of the planet’s plant + animal species, also triggered a #megatsunami with mile-high waves. Recent historical tsunamis pale in comparison with this globally catastrophic event, .."

I think Frederik Pohl would be pleased that the crater named after him caused this.
