Hi, I’m Brian Olson—geologist, earthquake nerd, & SoCal resident. With 25+ years in engineering geology, I tackle hazards like liquefaction, landslides, & active faults. Expect posts on quakes, geology, travel, Disneyland, & how the Angels break my heart. 🌍🏰⚾
DAS Bump!
My summary of this morning’s session: “Forecasting Earthquakes with Continuous Data: From Lab to Field”. Sounds like a SCEC German punk band. #scecmeet

Opening presentation of this year’s SCEC annual meeting in Palm Springs! It seems SCEC is a “large Enterprise” working to develop & share cutting-edge earthquake system science to enhance California’s resilience & to educate and inspire future scientists. #scecmeet #SCEC2025 🧪

I'm guessing there was a real reason that the new pope served as the bishop of Chiclayo, but I'm going to pretend that whoever was doing the bishop assignments misheard it as Chicago and was like "great we can just promote one of our Chicago guys".

Us geologists here at the @cageosurvey.bsky.social LA office all got our early warning notifications on our phones so we were prepared for some shaking. Did you get one too?

Felt the long-period shaking here in downtown LA from the M5.2 earthquake near Julian, CA (San Diego County). Epicenter is near the Elsinore Fault, which would be the primary suspect, but we'll see once more data comes in. #earthquake #Julian 🧪 @cageosurvey.bsky.social

You’ll forgive my concerns over a possible upcoming recession. I lost my job and almost lost my house in the last one.

What do the Republicans and the oligarchs fear most? Solidarity between poor rural whites and Black urban folks.
They have always feared it. It’s time to come together, friends. Our futures are bound up together.

Anyone have any insight into why this M3.1 in the Sacramento delta is SO deep? 🧪

Folks attending the @geosociety.bsky.social Cordilleran conference - roll out of bed early, grab a ☕️ and head over to the Granada Room to catch my 8:00 am talk! Then stick around to learn about liquefaction hazards in Sacramento from @brianolson.bsky.social at 9:10. 😎

If you're at the GSA Cordilleran Section meeting in Sacramento tomorrow, stop by the "Earthquake Hazards in Applied Geology" session tomorrow morning and catch me and Wendy Bohon in action as we represent the California Geological Survey! 🧪 @drwendyrocks.bsky.social @cageosurvey.bsky.social

Help me... I'm reviewing a technical document and need to know... is it "0.5 inch" or "0.5 inches"? 🧪
Can't find any style guides or clear rules.

The USGS posted their aftershock forecast and they are saying there's a 40% chance of another M6+ earthquake in the next week. Certainly, there will be dozens to hundreds of smaller M4s and M5s. If you are in Bangkok, I doubt you'll feel quakes less than M6 though. Scary no matter what though.

That's one way to start your weekend! A M4.6 earthquake shook the Bombay Beach/Salton Sea area this morning, just before 10:30am local time. This part of California has been rumbling with small M1-2 quakes since March 1. This could be the main shock of that sequence. #earthquake 🧪
