My grad student's paper on thermal moonquake classification is out! Yuri Tamama found quakes originating from lunar boulders for the first time. Specifically from the one in the photo.

Interesting to see what congress people put on their doors. This was from my visit to DC. The weirdest thing was staffers from Appropriations didn't know if universities really had their money cut off. They asked us. (The answer is yes.) Lawmakers learn things at the last minute too from the WH.

In case you've never been in an aftershock sequence... this is a seismic record for the 2 days after the 1994 Northridge earthquake in northern LA. Most of these were felt by the public. The earthquakes continue after the big one.

The Lima, Peru earthquake reminds us about the effect an earthquake in southern California could have on properties at the edges of cliffs. The photo looks a lot like the PCH in Santa Monica.

The USGS published this map with NASA in 1972 months before Apollo 17 launched. They landed within a few miles of the target (pencil points to landing site). By this time they landed people on the moon successfully 6 times. This was before PCs, GPS, etc.

It looks like my offshore MT project with Scripps will finally happen. The equipment is in Mazatlan. It was originally set back a year due to COVID. Here's the proposed ship route.

The last known original seismogram from the 1933 Long Beach earthquake. This earthquake jumpstarted earthquake engineering in California.

The @caltechseismo.bsky.social is the orange dot in the image. It is where we run the Southern California Seismic Network. The fires have not affected our earthquake reporting, nor earthquake early warning because of the great efforts of our team at Caltech and the USGS. Great work!
