C’è stato il secondo tsunami più grande della storia con un’onda alta quasi 500 metri (e nessuno se ne è accorto) trib.al/vJoNbty

Gelombang megatsunami dahsyat yang terbentuk ketika gunung es di Alaska runtuh ke laut pada 2025 adalah tsunami tertinggi kedua yang pernah tercatat (hampir 500 meter).
Gelombang ini jadi pengingat akan risiko yang ditimbulkan oleh mencairnya gletser.

The 2nd largest tsunami ever recorded struck Alaska's Tracy Arm Fjord on August 10, 2025, about 50 miles southeast of Juneau.
The wave reached a staggering 1,580 feet tall.

Ever wonder what a ~480 m (1550’) tsunami might look like? Using the tsunami hydro modeling in our paper out today in Science on the mega-landslide-tsunami in Tracy Arm, Alaska, we have created a few compelling animations that you might enjoy.

Another huge landslide and tsunami in coastal Alaska yesterday morning. Still a bit of a puzzle, but working with the @AKearthquake source location, the timing of waves from eyewitnesses on Harvest Island and in Endicott Arm, and the @NOAA Juneau tide gage recording, it appears that a massive slide occurred ~5 km east of the end of Tracy Arm. With this info guiding simulations, a plausible/likely scenario (there are others!) is that the slide ran down Sawyer Glacier, impacted into the water at the end of Tracy Arm, and displaced somewhere between 100-200 million cubic meters of water. A simulation with this info matches eyewitness tsunami observations and the tide gauge, shown below. Animation here as well. If this source pans out (the slide location is still uncertain – need satellite imagery to confirm), there were likely *very* large waves within ~5 km of the slide-water impact location at the end of Tracy Arm.

Happened to be in Corvallis for a meeting, decided to drive down to Crescent City to document the tsunami in the harbor. Made it there just before midnight last night and stayed into the morning. Many surges like that shown in the video below, which was taken a bit before 7 AM.

busy few days... For the wave nerds, check out the tide gage in Santa Barbara Harbor last Thurs afternoon during the first swell. 1 m crest-to-trough harbor sloshing at low tide. Similar wave height as the Hunga Tonga tsunami of 2022. Likely the... #cawx #waves #SantaBarbara

... very long period (and large height) swell matched a resonant period of the harbor at low tide, and the ringing was strong.

Significant tsunami waves appear to be incoming (peak to peak waveheight of 1.5 m) at Toyama sea level station due to M7.5 earthquake near west coast of Japan

#TBT To the El Nino winter of 1982/83 one of the largest and most destructive on record. The intensity of the swell coupled with the high tide brought the waterline all the way up the beach and across the bike path causing massive areas of flooding and beach erosion.

3) there is evidence of very large atmospheric gravity and acoustic waves in the near field. The gravity waves would travel at a speed closer to tsunami waves in these depths. Not much attention here yet, but should be tsunamigenic…

4) and finally, the Lamb wave... How is it generated for this event? Surface pressure data in the near field indicates this atmospheric wave/pulse had strongly variable speed within 1000 km of the volcano. How/why? This has O(1) implications on the tsunami in the Pacific.
