I wasn’t able to make it to the @seismosocam.bsky.social meeting but @seislologist.bsky.social was kind enough to send me this years seismology shirt so that I could feel included from afar. Thanks Adam!

Fault creep on the Maacama fault, with @timblor.bsky.social

I had a heart procedure yesterday. Bad news: it was unsuccessful Good news: I’m on bed rest for a few days. (Photo-during admission)

Looks like the M5.5 Nevada quake was widely felt in the foothills of the Sierra Nevada. earthquake.usgs.gov/earthquakes/...

M 5.7 earthquake 18 km SE of Silver Springs, Nevada I felt it here in Sacramento!!! earthquake.usgs.gov/earthquakes/...

Who wants to learn about earthquakes in Kentucky? 🧪 youtube.com/shorts/cy1P4...

I love this photo of astronaut Christina Koch looking back at Earth from Artemis II. She's the first woman to see the full sphere of our beautiful planet. Welcome home to the crew, and thank you for reminding us of all we can discover together.

Science is good. We should fund it.

Did you hear or feel the sonic boom from the Artemis II reentry? Fill out a “Did You Feel It?” report! It will say earthquake but fill it out for the boom. earthquake.usgs.gov/earthquakes/...

The kids said they wanted toast for breakfast. 😒

If anyone happens to be near Lucerne, I recommend this lunch spot.

I made time today to drive home along the Avenue of the Giants and I’m so glad!

I’m fascinated by creeping faults and this week I finally got to visit some examples of fault creep along the Maacama fault in Willits, CA with @drwendyrocks.bsky.social

I’m so excited to visit the north coast of California this week!

Oh to be a cat, sleeping in a sunbeam.

Joshua Tree National Park is renowned for its forests of Joshua trees, its namesake species. Though less well known but similarly recognizable, the geology and geomorphology are equally important to the iconic landscape that attracts millions of visitors each year.

Listening to my kids cracks me up! Kid 1: I have bigger fish to swallow. Kid 2: I don’t think that’s the saying. Kid 1: Bigger fish to catch? 2: ….eat? 1: ….boil? 2: ….bake? 1: …..? 2: Why are we talking about fish again?

Sometimes the internet is scary, and I’ve been here a minute and have a pretty thick skin. 😳

A lot of cool things to see on this seismic recording from the Bay Area. At the top you can see the last of seismic waves from the M7.4 in Indonesia, “1” marks the waves from the M6.2 aftershock, and the “3” marks the location of the M4.6 near Boulder Creek, CA.

I can’t watch launches. 🚀 I am of the Challenger generation. The trauma is real.

The mission of the California Geological Survey is to provide scientific products and services about the state’s geology, seismicity, forests and watersheds, and mineral resources that affect the health, safety, and business interests of the people of California.

On March 24, 2026 there was a M7.5 quake near Tonga, and less than a week later there was a M7.3 near Vanuatu.

Trans friends, thank you for being you, and for, when you can, sharing yourselves with a world that is so frequently undeserving of the light you bring to it. I love and support you, always. 🏳️‍⚧️🫂🫶

Ok, so it was a medium sized impact 15 million years ago but still not to bad for off the top of my head! And I stand by the arrest.

Between March 23 (12:00 AM PST) and March 29 (11:59 PM) there were 46 earthquakes in California of magnitude 2.0 or larger. 🔸41 earthquakes between M2.0 - 2.9 🔸4 earthquakes between M3.0 - 3.9 🔸1 earthquake between M4.0 - 4.9 The largest earthquake was a magnitude 4.1 near Ludlow, CA.

A tsunami can move more than water. 🌊 Understanding how #tsunami debris and sediment moves and where it might end up is a critical part of preparing for and recovery from a tsunami. 🔍Explore more: www.conservation.ca.gov/cgs/tsunami/...

🌊 #Tsunami are a series of powerful waves often caused by underwater earthquakes or landslides. As tsunami waves approach the shore, they build in size, their currents intensify, and they become a threat to life & property. Go to tsunami.ca.gov for more information.

I’m on the fence about these articles. On the one hand, it’s a good reminder that California is earthquake country. On the other hand, we have 30-60 magnitude 2+ earthquakes every week, on average. www.edhat.com/news/santa-b...

M 7.6 earthquake 153 km W of Neiafu, Tonga earthquake.usgs.gov/earthquakes/...

Between March 16 (12:00 AM PST) and March 22 (11:59 PM) there were 48 earthquakes in California of magnitude 2.0 or larger. 🔸41 earthquakes between magnitude 2.0 - 2.9 🔸7 earthquakes between magnitude 3.0 - 3.9 The largest earthquake was a magnitude 3.7 near Petrolia, CA.

I have a joke about earthquakes but I can’t predict when to tell it

Pi Day Observed

Between March 9 (12:00 AM PST) and March 15 (11:59 PM) there were 43 earthquakes in California of magnitude 2.0 or larger. 🔸40 earthquakes between magnitude 2.0 - 2.9 🔸3 earthquakes between magnitude 3.0 - 3.9 The largest earthquake was a magnitude 3.3 near Rio Dell, CA.

It was a gorgeous sunset on the river tonight and I brought a little of that peaceful back for you. ❤️

A few years ago, Jenda Johnson and I made a “Women in Geoscience” video series where inspiring scientists describe their work, their interests, and their desire to inspire young women to pursue STEM and STEAM. Please enjoy! (Funded by IRIS and If/Then) www.iris.edu/hq/inclass/v...

In 1896, Florence Bascom became the first woman to work for USGS! She was also the first woman to earn a Ph.D. from @jhu.edu (in 1893) and created the geology program at Bryn Mawr College. She retired at age 74. #WomensHistoryMonth
