#FieldPhotoFriday Heat can really take its toll on our equipment! One of our stations near Agua Caliente recently got a new battery to replace one that was less than 2 yrs old. Surface temps over 150° F have been logged at this site! That heat for months on end is brutal on tech! #ShakeAlert #CalOES

#FieldPhotoFriday #EarthquakeHistory #Caltech This week, station CI.RVR in Riverside marks 100 years of continuously cataloged seismic data!
Its story starts back at the beginning of the Seismological Laboratory itself.

#FieldPhotoFriday near Mountain Pass, on the road to Las Vegas. Our field crew visited to replace an aging battery and keep out some unwanted rodent guests. The station is back in good shape, with sweeping views of the mine and surrounding desert. Time for the rodents to find a new place to stay.

#FieldPhotoFriday A little backup goes a long way! Connection issues kept our station near Cajon Pass from reliably supporting #ShakeAlert. Our field crew added satellite alongside cellular telemetry, keeping data flowing for quake detection and early warning. #CalOES

#FieldPhotoFriday takes us to a remote station in the Turquoise Mountains. A power charger update is planned soon to minimize fluctuations and keep the station running reliably. This background maintenance helps keep the SCSN resilient and ready. #ShakeAlert #CalOES

#FieldPhotoFriday In honor of #NationalWildlifeDay we went through and found some pictures of the times when the field crew encountered animals! Some of our stations are hosted on farms around the state so plenty of farm animals and the occasional wild animal!

#FieldPhotoFriday It's National Red Wine Day, so this week's site is a bit closer to home, The Athenaeum’s wine cellar on the Caltech Campus! Due to its proximity Margaret occasionally stopped by on her tours. It isn’t often that you see cases of fine wine on a solid platform with seismic equipment!

#FieldPhotoFriday For 11 years so far, this seismic station has been upgraded, maintained, and looked after by our hard working field crew. These photos from visits over the years show the ongoing work that keeps the network modern, resilient, and ready when SoCal shakes. #ShakeAlert #CalOES

This week, we remeasured Pinus halepensis permanent plots for the 8th time since 1965. Some plots have been logged following regular #forest management in the area, but most are still standing #FieldPhotoFriday

Visit to our mixed Mediterranean forest monitoring site to downloading data from point dedrometers and soil moisture sensors. After a rather rainy Autumn, the site is much greener and wetter that it has been for a long time. How will trees benefit from this extra moisture? #FieldPhotoFriday

#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.

Times like this I am very grateful for my students like @dougbonno3 and the electronics repair training he received in the military! Field surgery to our survey vessel so @sias_uwt field geology class can continue. #fieldphotofriday

Take a look at one of our field biologists in action, conducting a macrophyte survey in a stream. Using a specialized rake, they toss it into the water, let it sink, and then retrieve it to identify and count the aquatic plants.

Surveying stream beds (and trash) earlier this week. I can’t wait to see how the surveys compare to the ones we did last summer, because my eyes tell me there were some changes at most of our sites. #FieldWorkFriday #FieldPhotoFriday #urbanStream #TrashyStreams

Have you ever seen a tarantula hawk attack a tarantula? I have and it's awesome (though not for the tarantula)🕷️☹️
😎 nature is so freaking cool & a little terrifying...
Also apparently the sting of those little devils is something fierce 😬
