Terrestrial LIDAR investigation of the December 2003 and January 2007 activations of the Northridge Bluff landslide, Daly City, California Terrestrial LIDAR investigation of the December 2003 and January 2007 activations of the Northridge Bluff landslide, Daly City, California
On December 20, 2003 and again on January 1, 2007, landslides occurred along the coastal bluff that forms the west boundary of Daly City, California sending debris as far as 290 meters downhill and 90 meters into the ocean. This area is known for large landslide events where 150-meter tall coastal bluffs extend southward along the west boundary of San Francisco and San Mateo Counties...

Land-based lidar mapping: a new surveying technique to shed light on rapid topographic change Land-based lidar mapping: a new surveying technique to shed light on rapid topographic change
The rate of natural change in such dynamic environments as rivers and coastlines can sometimes overwhelm the monitoring capacity of conventional surveying methods. In response to this limitation, U.S. Geological Survey (USGS) scientists are pioneering new applications of light detection and ranging (lidar), a laser-based scanning technology that promises to greatly increase our ability...

Remote sensing observations of landslides and ground deformation from the 2004 Niigata Ken Chuetsu earthquake Remote sensing observations of landslides and ground deformation from the 2004 Niigata Ken Chuetsu earthquake
In recent years, major developments in remote sensing have made it possible to use these technologies to document the effects of earthquakes. Specifically, high-resolution satellite imagery and three-dimensional laser scanning (LIDAR) can provide important observations of earthquake damage that supplement traditional observations from field reconnaissance. The 2004 Niigata Ken Chuetsu...

Applicability of terrestrial LIDAR scanning for scientific studies in Grand Canyon National Park, Arizona Applicability of terrestrial LIDAR scanning for scientific studies in Grand Canyon National Park, Arizona
In November 2004, an experimental high flow release of water from Glen Canyon Dam into the Colorado River through Grand Canyon National Park in Arizona was conducted. The goal of the experiment was to evaluate the use of high flow events as a management tool for the preservation and restoration of natural resources in the Colorado River below Glen Canyon Dam. The U.S. Geological Survey...

LIDAR & SASW technologies for geotechnical earthquake engineering LIDAR & SASW technologies for geotechnical earthquake engineering
Geotechnical engineering methods are validated through comparison of field‐data of surface deformations and sub‐surface state properties. Recent advances in non‐invasive surface imaging and sub‐surface stiffness characterization allow us to rapidly and inexpensively map these spatial and physical properties in two and three dimensions. In this paper, we discuss new technologies used at...

The internal structure of sand bars on the Colorado River, Grand Canyon, as determined by ground-penetrating radar The internal structure of sand bars on the Colorado River, Grand Canyon, as determined by ground-penetrating radar
High-resolution, subsurface imagery from ground-penetrating radar (GPR) has revealed the internal structure of sand bars at seven sites on the Colorado River, Grand Canyon. Based on reconnaissance-level surveys, we recognized three stratigraphic units and several intervening unconformities. Unit A, which exhibits hyperbolic reflections and always occurs at the base of the section, is...
