Locations of the July 2019 Ridgecrest, CA earthquake epicenters and five USGS groundwater-monitoring sites with corresponding hydrographs. Effects from the two earthquakes were observed in several USGS continuous groundwater-level monitoring sites in California, Nevada, and Arizona.

On July 8, 2019, California Geological Survey and USGS geologists and geophysicists with National Guard and Navy personnel, view the road damage resulting from 3 to 5 feet of right-lateral motion near the expected maximum slip locality along the primary tectonic rupture associated with the M 7.1 Ridgecrest earthquake on July 5, 2019.

Vegetation grows abundantly on a once-flooded region of the Santa Ynez River. Located 5 ft adjacent from this picture is the actual flowing region of the stream. It is impressive to see the abrupt change in vegetation near stream environments.
