CGS and USGS geologists and geophysicists with National Guard and Navy personnel plan next phase of helicopter-supported field investigations on Sat., July 6, 2019 at China Lake NAWS.

Fault scarp close to the epicenter. In this location the fault has a main strand where much of the slip occurred, as well as distributed fractures.

Measurement of fault offset being done by USGS scientist Ken Hudnut, using the offset of a painted road stripe. This measurement was conducted following the Magnitude 6.4 earthquake that struck Searles Valley on July 4, 2019.

Janis Hernandez (California Geological Survey) measures 18 centimeters of offset across one strand of the fault rupture zone. This measurement was conducted following the Magnitude 6.4 earthquake that struck Searles Valley on July 4, 2019.

On July 4, 2019, a Magnitude 6.4 earthquake struck Searles Valley, CA. This photo provides likely evidence that the fault that hosted the earthquake ruptured to the ground surface.

These four images show the change in the area and level of water at the bottom of Halema‘uma‘u spanning August 9 to 13. Rocks in the center of the pond and near the shoreline help show the change in the waterline.

House destroyed by Palu earthquake-induced liquefaction. Note standing water which indicates a nearly surface-level water table that contributed to the widespread liquefaction.

Different portions of the ponds have different colors, presumably reflecting different amounts or varying chemistry of dissolved particles in the water.

Two red sea urchins (Mesocentrotus franciscanus) sit on the deck of the R/V Falkor. These sea urchins were collected during the #HuntingBubbles research cruise led by the USGS and Schmidt Ocean Institute, which focused on exploring and understanding methane seeps and the communities that depend on them along the Cascadia Margin.

On August 7, HVO geologists measured temperatures and documented the rock layers exposed as sections of Highway 132 buried by lava during the 2018 lower East Rift Zone eruption are "ripped" (shown here) to reopen the road. USGS photo by C. Parcheta, 08-07-2019.

Marine geochemist Renee Takesue collects a sample of exposed mud in a marsh near Sonoma Creek, California. She will look here and in nearby San Pablo Bay for chemicals from the 2017 Nuns Wildfire that can harm wildlife. The stormy winter of 2018 may have transported these contaminants from the Sonoma Creek watershed into San Pablo Bay National Wildlife Refuge.
