Costs and consequences of natural hazards can be enormous; each year more people and infrastructure are at risk. We develop and apply hazards science to help protect U.S. safety, security, and economic well being. These scientific observations, analyses, and research are crucial for the Nation to become more resilient to natural hazards.

Geologic Framework for Seismic Hazards in Central Virginia

The Central Virginia seismic zone (CVSZ) comprises an area of about 13,000 km2 in the Piedmont of central Virginia; seismicity in this zone is relatively frequent, but generally mild in magnitude. The August 2011 event was the largest earthquake recorded in the CVSZ since the development of modern seismic monitoring, and highlighted how little we actually know about this seismic...

Introduction to Geomagnetism

Geomagnetism is the study of the Earth's magnetic field. This includes the fields produced by the Earth as well as those interacting with the Earth. Internal dynamo processes within the Earth create slowly changing magnetic fields. The continuous flow of particles and fields from the Sun (called the solar wind) interacts with the Earth's magnetic field. Strong, transient impulses due to solar...

    Biogeomorphic classification and images of shorebird nesting sites on the U.S. Atlantic coast

    Atlantic coast piping plover (Charadrius melodus) nest sites are typically found on low-lying beach and dune systems, which respond rapidly to coastal processes like sediment overwash, inlet formation, and island migration that are sensitive to climate-related changes in storminess and the rate of sea-level rise.

    Why aftershock duration matters for probabilistic seismic hazard assessment

    Most hazard assessments assume that high background seismicity rates indicate a higher probability of large shocks and, therefore, of strong shaking. However, in slowly deforming regions, such as eastern North America, Australia, and inner Honshu, this assumption breaks down if the seismicity clusters are instead aftershocks of historic and...
