Imaging identifies a transition to supershear rupture at the Mendocino Triple Junction (MTJ), indicating a role of changes in geologic structure on rupture process. Fiber-optic cables (and distributed acoustic sensing, DAS) may help to monitor offshore earthquakes.

Calif. could detect massive earthquakes with internet cables. Here's how.

The same high-speed tech that brings you HD movies could also measure earthquakes.

Fascinating new results from @atterholt.bsky.social and colleagues who use seismic signals recorded on a fiber-optic cable near Arcata, California to learn about the earthquake rupture process of the 2024 magnitude-7 offshore earthquake.

Indeed.
The fallacy here is equating "you shouldn't automatically assume someone is right because they're a subject matter expert" (fair enough) with "you should automatically assume someone is wrong because they're a subject matter expert" (laughably absurd).

Jim Beller @jimbee.bsky.social · Aug 30

It's true that "appeal to authority"is a logical fallacy. Following scientific consensus is more logical than seeking out crackpots.

The 1755 earthquake and tsunami that devastated Lisbon, Portugal aren’t well understood. New research suggests that large-scale delamination of the Earth”s mantle may have been the cause. Seismic hazard is highest near existing plate boundaries, but it exists elsewhere.

This was NOT a 1500-ft tall wave traveling away from the landslide.
The 1500-ft number has been described as the splash caused by impact of the landslide with water in the fjord. Wave heights in the fjord were very high, however.

NASA plays a key role in earth science, contributing critical information from its earth-observing satellites. For earthquake hazards, these data are important for characterizing details of the earthquake rupture, extent of faulting, and remote sensing estimates of damage to buildings.

It has been a busy couple of days! There was a large landslide and tsunami in SE Alaska, in Tracy Arm, Sunday morning. Luckily, no injuries or casualties were reported. This region is outside of our current landslide coverage, but we were able to get a quick location after hearing about the event. 🧵

As I wrote in @thehill.com, federal science funding isn’t just about labs, it’s about livelihoods. Cuts to NIH, NSF & NASA mean lost jobs today, stalled discovery tomorrow, and fewer opportunities for the next generation. When we invest in research, we are investing in workers and communities. ⬇️

Trump’s cuts to science & innovation could stall innovation, eliminate jobs, and undermine U.S. global competitiveness. @alondra.bsky.social explains for @TheHill.com:

The administration is attacking America’s opportunity engine

The damage is already apparent. A future Congress may want to restore funding, but talent pipelines, lab capacity and institutional knowledge cannot simply be switched back on.

This looks consistent with (official) reports of 10-20 m run-ups in Kamchatka/Okhotsk. With complex topo/bathy short wavelength features like the waves seen here can develop and superimpose on the long period tsunami. We've seen this in other places. Time will tell if this can be verified

A M8.8 earthquake just ruptured the subduction zone offshore Russia’s Kamchatka peninsula. This is one of the world’s truly huge earthquakes, and a triggered tsunami is currently traveling across the Pacific ocean.

This same fault ruptured on July 20th in a M7.4, and last August in a M7.1.
