Rockfalls have been a frequent occurrence in Halema‘uma‘u crater, both before and during the current eruption. Debris from a recent rockfall can be seen sitting on the solidified lava lake crust (center). The crust on the southern edge of the lava lake is thick enough to support the weight of the boulders that have fallen. USGS photo taken by B.

In February of 2021, scientists from the USGS Woods Hole Coastal and Marine Science Center and Woods Hole Oceanographic Institution (WHOI) conducted near-shore bathymetric surveys on Cape Cod National Seashore. Bathymetry is the study of underwater depth of ocean floors or lake floors.

A close-up view of the western fissure, which is supplying lava to the lava lake in Halema‘uma‘u crater. A slow-moving lava stream marked the inlet where lava entered the lake. Several incandescent openings remain over the vent region. USGS photo by M. Patrick.

Eruptive activity continues in Halema‘uma‘u crater, at the summit of Kīlauea. The active surface lava remains largely confined to the western (left) portion of the lava lake. As of the afternoon of January 31 lava had filled about 212 m (695 ft) of Halemaʻumaʻu in the active western portion of the lava lake. USGS photo by M. Patrick.

In August of 2020, the enormous CZU wildfire complex consumed over 85,000 acres in San Mateo and Santa Cruz Counties, leaving scarred landscapes in the hilly region. Runoff from large rainstorms in the winter months carry contaminants from the soils within these burned-out forests.

A two-day rainstorm from January 26-28, 2021 caused numerous mudslides, debris flows, and other issues along California's coastal Highway 1 through Big Sur. This section is just north of Kirk Creek, at a drainage where mud was washed across the roadway. Plumes of the muddy runoff are clearly visible in the ocean.

The storm that hit California’s coast between Jan. 26 and 28, 2021, blew out a portion of Hwy 1 near Big Sur. On Saturday, a USGS reconnaissance flight snapped this dramatic photo above the Rat Creek drainage showing the debris flow.

A two-day rainstorm from January 26-28, 2021 caused numerous mudslides, debris flows, and other issues along California's coastal Highway 1 through Big Sur. This section is just north of Wild Cattle Creek. Mud washed across the roadway from the cliffs in numerous locations along the 70+-mile stretch of this scenic coastal road.

California's Highway 1 snakes its way along the steep terrain of the Big Sur coast. The bridge over Villa Creek can be seen in the left of the photo, as well as a retaining wall built under the freeway towards the center. These are just a few of the engineering feats by Caltrans to keep the roadway intact.
