USGS Research Spotlight: Subduction May Recycle Less Water Than Thought

Dr. Nathan Miller, Research Geophysicist from the USGS Woods Hole Coastal and Marine Science Center,  led a study on new analysis of seismic data from the Middle America Trench suggesting that previous calculations have vastly overestimated the total amount of water transported to the mantle worldwide.

USGS Study on Threatened Coral Can Guide Reef Restoration

Nursery-grown elkhorn coral transplanted into Dry Tortugas National Park survived and thrived, growing twice as fast as corals planted in other locations in the Florida Keys, according to a new U.S. Geological Survey study published in Endangered Species Research.

The Disaster that Helped the Nation Prepare for Future Earthquakes: Remembering San Fernando

The San Fernando earthquake struck Southern California 50 years ago, killing 64 people and costing over $500 million in damages. The quake prompted federal, state and local action to reduce earthquake risks and bolster public safety.

Intense storm washes out Highway 1 in Big Sur . . . again

USGS researchers respond to coastal hazards and wildfires: The intense storm that hit California’s coast between January 26 and 28, 2021, blew out a portion of Highway 1 near Big Sur. USGS works diligently to provide officials with science to help inform their decision making before, during, and after such events. Here, we present photos that describe this work.

Who’s Sharing? Inconsistent Eyewitness Accounts Can Affect How We Understand Earthquakes

Scientists rely on seismometers and eyewitness accounts to identify an earthquake’s location, time and magnitude. A new study explores how the latter can be limited by socioeconomic factors, which can create biases in datasets that scientists use to characterize seismic hazards and coordinate emergency response.

Federal Agencies Partner to Strengthen ShakeAlert Earthquake Early Warning Capacity Along the West Coast

A lone solar panel in the middle of California’s largest national forest is powering a seismometer able to detect Earth’s vibrations, a piece of the puzzle necessary to help protect life and property by providing critical seconds of warning that an earthquake is occurring and shaking is imminent.

Groundwater discharge impacts marine isotope budgets.

Groundwater is an important pathway for materials to flow from land to sea. This is particularly true for materials that are concentrated in groundwater due to chemical interactions between water and aquifer rocks as groundwater flows to the coast.
