A USGS electronics technician performs maintenance on a ShakeAlert Earthquake Early Warning (EEW) sensor station, located in the San Francisco Bay Area. ShakeAlert station components include strong-motion accelerometers, solar panel and battery power systems, and communications & telemetry equipment for communication with the wider ShakeAlert network. 

Mount Shasta, a steep-sided Cascade Range stratovolcano in Northern California, looms above Little Glass Mountain, a thick obsidian flow erupted from the Medicine Lake shield volcano about 1,000 years ago. These are just two of the young volcanic areas monitored by the USGS California Volcano Observatory. USGS photo.

Maintenance of high quality ShakeAlert sensor, power and telemetry station in the San Francisco Bay Area in California.

Miriam Jones holding a peat core that was extracted from a thawed permafrost bog at the Alaska Permafrost Experiment (APEX) site at Bonanza Creek LTER, Alaska. The boundary between the formerly frozen permafrost plateau and thawed bog is visible in the peat stratigraphy, with the light-colored peat indicated thawed bog.

These two NOAA satellite images show Cape San Blas Road in the Florida Panhandle town of Cape San Blas before Hurricane Michael, and after the Category 5 storm. The red circle shows where the USGS sea turtle researchers' field station and seasonal home once stood. The building was demolished down to the concrete slab.
