I’ve always loved digging, but these 3m deep, rock hard snow pits in Antarctica in 2020 tested that love. #fieldworkfriday #fieldphotofriday

Fieldwork isn’t always hot and sunny! Our field crew has seen some stunning snowy days in the past – a cool reprieve from the typical California heat. #FieldPhotoFriday #snowday

#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!

#FieldPhotoFriday is back! Cold mountain air, wide-open views, and one of our seismic stations high above the Banning area. Not a bad office/field location! Beautiful scenery and a great place to keep watch on Southern California’s seismic activity.

#FieldPhotoFriday Out in the desert, our team regularly visits our remote seismic stations. These stations are invaluable to the Southern California Seismic Network (SCSN), delivering critical data that helps us detect and analyze earthquakes within seconds.

#FieldPhotoFriday Students, faculty, and SCSN staff recently came together to test a new geophone array, detecting seismic refraction and imaging subsurface structures. This project highlights our commitment to using advancing tech and training the next gen of seismologists!

#FieldPhotoFriday Running a seismic network in SoCal isn’t easy—dense population, rugged terrain, and constant quakes! Caltech & USGS work year-round on gear, data, & site visits. Here’s a look at 35 years of fieldwork in the Alvord Mountains!

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

#FieldPhotoFriday We all know that weather doesn't cause earthquakes, RIGHT?!, but it can affect seismic stations. From flooding, to wind, fires, and more, our stations are out in the elements. Recent storms blocked the sun long enough to show us that this station may need some battery maintenance!

#FieldPhotoFriday Sometimes maintaining a seismic station includes a checkup after a major fire. Recent fires near Mt. Baldy, and elsewhere in the state this year, were a reminder that SoCal is susceptible to more natural disasters than just earthquakes! Lucky for us, this station survived the fire.

#FieldPhotoFriday Another beautiful (though unseasonably warm) trip out to one of our stations near Porterville. The crew went out last week to replace a number of pieces of equipment and made some upgrades, as well as cleared up some water damage. Great work and nice to see data rolling in again!

#FieldPhotoFriday Maintaining a seismic station's health involves many factors - data telemetry, power, geologic conditions, and more can all impact its performance. In this case, seasonal changes caused nightly power outages!
