Heading to #SC25 where our “Team Cascadia” presents the digital-twin #HPC framework integrating Bayesian inference at extreme scale towards real-time, physics-based tsunami early warning that earned us a place among this year’s ACM Gordon Bell Prize finalists.

Nice story in the Seismological Society of America (SSA) News on the Paul Andrew Spudich Fund supporting Jeena Yun and Baoning Wu’s travel to Japan, to attend the slow-to-fast workshop. I enjoyed the featured “happy” Easter egg in Spudich & Frazer (1984).

Great to speak about how last week's tsunami impacted San Diego, just half a foot at La Jolla Shores (and yes, I’ll be keeping a "camera-ready jacket" in my office from now on).
Now is a good moment to review tsunami evacuation routes and flood zones in your area!

Looks like a small swarm in the Fontana trend. This M4.2 had a few foreshcoks including a M3.0. The Fontana trend is a NE-striking lineation of earthquakes under the sediments of the San Bernardino Vslley. We believe it is one of the left-lateral striking faults that are south of the San Gabriels.

Did you feel the M4.4 earthquake near Muscoy, CA, a few minutes ago? The ShakeAlert earthquake early warning system was activated. ShakeAlert estimated the magnitude at M4.7, which meets the criteria for issuing alerts to cell phones in the area near the earthquake.

"This was the largest earthquake since 2011, the sixth largest on record globally," said Alice Gabriel (@inseismoland.bsky.social), a seismologist with @igpp.bsky.social at Scripps Oceanography. "The first tsunami wave reached La Jolla Shores around 1:45 a.m., registering less than half a foot."

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.
