USGS Geologists R. Sickler, J. Willard, and B. Philibosian observe as an excavator digs a pit used to investigate sediments uplifted by active tectonic activity in the San Joaquin – Sacramento Delta, California, November 29, 2021.

A telephoto view of the west vent along the western wall of Halema‘uma‘u crater at the summit of Kīlauea. On November 9, spatter bursts in the west vent cone triggered sloshing on the surface of the ponded lava. Spatter was thrown about 6–9 m (20–30 ft) above the pond surface and occasionally deposited onto the rim of the cone.

 The USGS Gas Hydrates Project develops and tests new tools to address the critical knowledge gaps identified as scientists analyze hydrate-bearing pressure cores recovered during field programs. HyPrCal Laboratory analysis using Pressure Core Characterization Tools.

Rockslide on California State Route 70 in the Feather River Canyon, Butte/Plumas county line, northern California. This slide was triggered on October 24, 2021 by a Category 5 atmospheric river, which released more than ten inches of rain in the area over a 48-hour period. Approximately seven thousand cubic yards of rock and debris buried and closed the highway.

The USGS “Chambers” site is located in the Plumas National Forest in northern California. The site consists of instrumentation monitoring the hillslope in the lower part of the image. The hillslope exhibits moderate soil burn severity and hosts sandy soils derived from granitic bedrock.

The USGS “Chips” site is located in the Plumas National Forest in northern California. The site consists of instrumentation monitoring the hillslope in the lower part of the image. The hillslope exhibits moderate soil burn severity and hosts silty soils derived from metamorphic bedrock.
