Attending the Cascadia Region Earthquake Science Center (CRESCENT) Partnerships & Applications workshop in Portland?
Stop by the ShakeAlert posters to learn more about and contribute ideas 💡 to the “Great Social Science for Great Earthquakes Project”!
We’re studying big earthquakes on the San Andreas Fault and the Cascadia Subduction Zone.
📽️Meet Samantha from UC Berkeley Seismology Lab who is one of the leads for this project.

In an ongoing effort to improve public safety, @CaltechSeismo & @USGS installed a seismic test station on the @Caltech campus. This station will be a testbed to improve earthquake monitoring and #ShakeAlert Earthquake Early Warning. @UOHazardsLab @PNSN1
Attached are a couple of photos that include Kyle Garcia and Ben Dunham during the install.

Happy #FieldworkFriday! At station OLQN near Lake Quinault, the sun is shining and the forest is thriving. Field staff visited recently to make repairs and upgrade the power system at this station, which contributes to the @USGS_ShakeAlert Earthquake Early Warning system.

Happy 🛠️ #FieldWorkFriday!
Last week, our field techs conducted tower training to practice rescues, techniques, and knot-tying.
Training like this helps ensure our team is prepared to safely support the critical monitoring infrastructure that protects Oregon!

Happy 🛠️#FieldWorkFriday!
This week, our field techs headed south to service a seismic site and cam.
At CAVE the team upgraded telemetry and converted the site’s batteries.
Over at Fiddler WF cam, the team realigned the radio link to boost connectivity and improve data flow.
