The SCSN & SCEDC want your feedback! We’re modernizing our systems and looking for community input to help shape future data products/services. The survey is open to everyone in the research community, even if you’ve never used our data. It takes ~15 min and runs through March 1.

In 2012 there was a M 7 earthquake close to the Mexican one today. This was the news that I was in at the time. They really had problems with my name. diario.mx/nacional/201...

The M6.5 earthquake in Mexico was on the coast in Guerrero near the border with Oaxaca. Based on my experience there will be some damage close to it, like tvs falling to the floor. Mexico City people will feel it, but no damage. The alarm sounded before the seismic waves arrived in Mexico City.

This is really cool.

I ran into Kip Thorne in the lunch room at Caltech. He said he did work with people from the Seismolab where I work before he retired. Nothing like meeting a hero.

Good news! www.youtube.com/watch?v=Z8JF...

My student and postdoc giving talks. Great job!

My research group at AGU.

Please allow me to introduce myself. I'm a man of wealth and taste. Pleased to meet you. Hope you guess my name.

Most if not all geophysics faculty at the R1 where I went to grad school would become ineligible for future federal funding if this ban passes congress. 🧪⚒️

Happy birthday, Marie Skłodowska-Curie! She was born November 7th, 158 years ago. Marie Curie was the first woman to win a Nobel prize, and to this day the only woman to win two Nobel prizes, which where Physics in 1903 and Chemistry in 1911.

Este sigue siendo de los mejores documentales de sismos en México... Y no solo porque me entrevistaron. www.youtube.com/watch?v=_DkR...

US Immigration uses facial recognition. I didn't need my passport to enter the country. Is that bad or good?

Oaxaca?

Marlena Shaw radio on the rotation today.

We celebrated the retirement of this great civil servant who dedicated his life to work he thought was important. He was a veteran and then a really great field engineer who designed our radio telemetry array in the desert. It is unfortunate that the hiring freeze means that there is no predecessor.

Congratulations to longtime USGS field tech Scott Lydeen on his retirement! Scott spent decades maintaining & upgrading SCSN stations across SoCal, always innovating and working hand-in-hand with Caltech staff. His legacy lives on, not least at the seismic site named after him. Thank you, Scott!

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.

So interesting tidbit I learned during my Capitol Hill visit. The house just passed a version of a continuing resolution that has language that allows the president to use the funds as he wishes. It makes it less likely to pass the Senate and more likely to go to gov shutdown.

I'm on Capitol Hill to talk about ShakeAlert.

With California representative Judy Chu.

Just arrived in DC. There's little to no evidence of the national guard here. I'm eating at a place downtown. i don't see much difference from when I was here in December.

Rep Maxine Waters is on my flight to DC today. Cool.

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.

Women's boxing in the 1700's. This is great! I got this since I'm a member of the Rest is History Podcast. #TheRestIsHistory

Is this what you would expect? www.pewresearch.org/short-reads/...

I was interviewed in a science podcast:

I had the best lunch I've ever had at Caltech. I randomly sat with astronomers at lunch working on SPHEREx who told me how they are looking back 14 billion years in time and I explained the various reasons we can't predict earthquakes including a little chaos theory. This is why I love academia.

The desire by Trump to take Greenland shows that he knows climate change is real since Arctic oil. Would you frame climate research to say when it that oil be available to save NOAA and NASA?

This is the greatest post I have seen in a while.

With NASA budget cuts... one scientist I know said he's been told that he's most likely losing his job by the end of the summer. Another is moving to Singapore since the job is more steady than at NASA. NASA started in 1958. Singapore sovereignty 1965.

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.

These are the people that make America great 🇲🇽🇺🇸

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.
