The pond within Halema‘uma‘u has notably widened and deepened since August 15, as shown in these two photos taken on August 17 (right) and August 15 (left). Note the changes in the neck between the two ends of the pond. USGS photos by D. Swanson.

The water level continues to slowly rise in Halema‘uma‘u, drowning many of the small rocks that were exposed in the center of the pond. Ripples across the water surface were also evident today.

Geologists with USGS, the California Geological Survey (CGS) and Naval Air Weapons Station China Lake (NAWS) worked together in response to the Ridgecrest earthquake sequence in California that occurred July 4-6, 2019. The earthquakes were large enough that the fault rupture reached the earth’s surface.

 Research scientist Meagan Gonneea and USGS intern Angela Trejo survey the Jones River in Kingston, MA. Removal of a dam across the Jones River began July 15, 2019, as a first step to restore river habitat, which is particularly critical for herring passage from the sea to inland lakes for spawning.
