#FieldPhotoFriday Big Rocks, sprawling views, and what... seismic data? Looks like the crew are one highway turn off away from Perfection, Nevada! Glad the crew got all of their recent equipment upgrades done before the Graboids got there! (IYKYK)

#SSA26 The Seismological Society of America Annual Meeting is here this week in Pasadena!
With so many from the SeismoLab and SCSN participating in talks, poster sessions, and events, it's a busy week! Keep an eye out, we'll be sharing highlights throughout!

As Artemis II made its reentry and splashdown last Friday, the Seismo Lab took a moment to watch. We may spend our days monitoring the Earth and how it moves, but we’re just as inspired by milestones beyond it, celebrating the science and accomplishments that connect and fascinate us all.
This week the CA Seismic Safety Commission Advisory Board Meeting was held at Caltech. The SSC works with federal, state, and local agencies to support earthquake preparedness, mitigation, response, and recovery. The Seismo Lab and SCSN are glad to be a part of this vital initiative! buff.ly/M4euFcQ
#FieldPhotoFriday A recent trip out to the Lebec area offered some great views while the crew upgraded an old radio, datalogger, and batteries. Glad they made it out there before the temperature really starts going up! (and I'm sure they are too)
It is a great reminder that even if you don't live near a single large fault, complexity can matter greatly when it comes to hazards!

The rupture extended some 120km producing ground deformation, including liquifaction and road/canal offset near Mexicali.
Thousands of aftershocks followed, which gave scientists one of the clearest looks at how multi-fault ruptures can behave in this region.
@EQHistory 16 years ago (yesterday) The M7.2 El Mayor-Cucapah earthquake occurred on Easter Sunday. It didn't occur on a single fault though, but across a network of different fault structures near the CA/Baja/Mexico borders.

#FieldPhotoFriday Throwback to a sandy day near Barstow, one of many maintenance trips that keep our seismic network running!
These pics may be from years ago, but the station is still going strong today after a recent upgrade and visit. Same site, new tech, and a more resilient network!
Even a few seconds of warning can make a difference. Whether that means moving to a safer position, locking wheelchair brakes, or protecting your head and neck.
Preparedness looks different for everyone, and outreach like this helps ensure these life saving tools are accessible to all.
Caltech Seismo Lab was proud to support the Abilities Expo, helping connect our community with earthquake preparedness resources and the benefits of ShakeAlert Earthquake Early Warning.
