This photograph shows ice-wedge polygons and an eroding shoreline at Cape Halkett on the Beaufort Sea coast of Alaska. Coastal erosion along the Arctic coast is chronic, widespread, and potentially accelerating, posing threats to infrastructure important for defense and energy purposes, natural shoreline habitats, and nearby Native communities.

Young mountain big sagebrush shown in the foreground are re-establishing in a native bunchgrass community 15 years after a fire along the Boise Front Mountains looking unto the Snake River Plain, Idaho.

Lava delta at East Lae‘apuki on the southeast coast of Kīlauea Volcano is about 17 hectares (43 acres). The delta extends about 400 m seaward from the sea cliff and is about 850 m long parallel to the shoreline. The steep sea cliff embayment resulted from collapses of earlier deltas; the collapses undermined and took away parts of the cliff.

Substantial cracks cutting across a lava delta are clear indication that the delta is subsiding as it grows across the unstable pile of interfingering lava flows and fragments built on the steep submarine slope. The larger cracks on this delta are 1-2 m (3-6 ft) wide.

USGS scientists Andrew Schwartz and Dan Hanes maneuver a current profiler for a study of surf-zone hydrodynamics at Ocean Beach, on the west side of San Francisco, California. Beach erosion has been a continuing problem in this area.

Helicopter overflight photo taken this morning - view toward the west directly above Kapoho Crater. The fissure 8 lava channel now bends sharply to the south on the western edge of the crater after being blocked and diverted yesterday.

Map as of 1:00 p.m. HST, July 11, 2018. Given the dynamic nature of Kīlauea's lower East Rift Zone eruption, with changing vent locations, fissures starting and stopping, and varying rates of lava effusion, map details shown here are accurate as of the date/time noted. Shaded purple areas indicate lava flows erupted in 1840, 1955, 1960, and 2014-2015.
