A new study argues that in the past, Cascadia quakes have triggered the San Andreas to go off, and that it could happen again. But other experts, while recognizing that may technically be possible, want more evidence. Read more at NatGeo: www.nationalgeographic.com/science/arti...

Are two of the deadliest earthquake zones in North America linked? It's possible—but controversial.

On July 29, 2025 a Mw 8.8 earthquake off Kamchatka launched a Pacific-wide tsunami, right as the SWOT satellite flew south-to-north taking altimetry measurements of the wave train. In our new preprint, we pair SWOT with nearby DART buoys to capture the tsunami’s propagation and its source

A sprawling collaboration with colleagues in Myanmar, Thailand, Singapore, China, and the US. Yes, undoubtedly super-shear, and unique because a set of trenches had fortuitously been opened at the Sagaing fault where the event nucleated a few years before the 2025 earthquake

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

Today is the anniversary of the Pacific Northwest's worst modern earthquake, the April 13th, 1949 mag 6.7 near Olympia. 8 people died, many were injured, and millions of $$ (in 1940's money) in damage. It was a "slab event" in the subducted plate at ~50 km depth.

Station NPW is ~250 km from the hypocenter. For that acceleration pulse to get to the site when it does rupture needs to be trucking along at ~5 km/s. Shear wave speeds at ~10km depth according to Litho1.0 are 3.46 km/s. The rupture is most likely, realy really, supreshear.
