Geologic Framework for Seismic Hazards in Central Virginia

The Central Virginia seismic zone (CVSZ) comprises an area of ~13,000 km2 in the central Virginia Piedmont; seismicity in this zone is relatively frequent, but generally mild in magnitude. The August 2011 event was the largest temblor recorded in the CVSZ since the development of modern seismic monitoring and highlighted how little we actually know about the CVSZ, including: 1) the...

Physical Properties by Geologic Unit in the Southern San Luis Basin, New Mexico

Physical properties of geologic units are important for geophysical interpretation because they provide the tie between lithology and geophysical fields. For gravity data, the applicable physical property is bulk density, which is the overall mass per unit volume of rocks, sediments, and their pore spaces. Bulk dry density is the mass per unit volume measured when the sample is dry. Saturated...

Quaternary sediment thickness and bedrock topography of the glaciated United States east of the Rocky Mountains

Beginning roughly 2.6 million years ago, global climate entered a cooling phase known as the Pleistocene Epoch. As snow in northern latitudes compacted into ice several kilometers thick, it flowed as glaciers southward across the North American continent. These glaciers extended across the northern United States, dramatically altering the...

Automatic delineation of seacliff limits using lidar-derived high-resolution DEMs in southern California

Seacliff erosion is a serious hazard with implications for coastal management and is often estimated using successive hand-digitized cliff tops or bases (toe) to assess cliff retreat. Even if efforts are made to standardize manual digitizing and eliminate subjectivity, the delineation of cliffs is time-consuming and depends on the analyst's...
