I am so excited for everyone to see this amazing story about the mysterious seismic signal, mega-tsunami, giant rockslide, and perpetual wave machine of a fjord! www.theguardian.com/environment/...
Landslide in Greenland caused unprecedented seismic event that shows impact of global heating, say scientists
It took military data, a complex tsunami simulation, 68 scientists, and one unfortunate bathtub experiment to find out what caused a bizarre global seismic event. www.quantamagazine.org/how-did-a-la...
Last year, an immense but brief outburst of seismic energy was soon followed by a long hum that made the world ring. Finding its cause took 68 scientists and an assist by the Danish military.
(For my part, I processed InSAR data over Dickson Fjord and was able to independently detect decorrelation consistent with the expected tsunami run-up around the edges of the fjord. I did not find any obvious pre-event signal on the rocky peak, but it certainly did decorrelate after it fell.)
First I heard of it was an email from @seismotom.bsky.social inviting colleagues to join an online discussion where he and many other seismologists were puzzling over this bizarre signal that they had independently detected on their seismic networks, with input from geomorphologists and modelers.
Out today! The results of an awesome multidisciplinary collaboration of dozens of scientists across the globe (including me, in a very minor role)! A rockfall into a glacier into a fjord in Greenland caused a tsunami and seiche that generated a monotonic seismic signal for 9(!) days!
Scientists launched an investigation after being baffled by seismic signals picked up across the world
