#FieldPhotoFriday With the weather cooling a bit, lets show at a site that is normally pretty hot, looking lush through years of field visits! This station near Murrieta is in a nursery so it's always got a good view of the city and greenery! I'm sure the crew likes the change.

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!

When an earthquake hits SoCal, SCSN acts fast. We automatically post preliminary info for all local M2.75+ events, often within minutes. Reviewed updates are available at SCEDC.caltech.edu, www.SCSN.org, and USGS.gov. @caltechquake.bsky.social • @caltechseismo.bsky.social
