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.

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.

The atmospheric river, a narrow, powerful track of water vapor that can deliver tremendous volumes of rain, hit the central California coast and stalled there between January 26 and 28, 2021 — with catastrophic consequences.

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.

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.

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.

On May 20, 2017, this section of the Big Sur coastline experienced a huge landslide that wiped out scenic coastal Highway 1. By July 2018 the roadway was reopened.

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 is Big Creek Bridge, and Big Creek is still murky. Plumes of the muddy runoff are clearly visible in the ocean.

On Sunday, August 16, 2020 at approximately 3:00 PM PST, the River wildfire ignited in Monterey County, California, just west of the Salinas River Valley.

The University of Puerto Rico Mayagüez, the Natural Hazards Center at the University of Colorado Boulder, and the USGS Landslide Hazards Program collaborated to create educational materials for residents of Puerto Rico to learn about how to prepare for, mitigate, respond to, and recover from landslides.
