Subaerial landslides at the head of Barry Arm Fjord in southern Alaska could generate tsunamis (if they rapidly failed into the Fjord) and are therefore a potential threat to people, marine interests, and infrastructure throughout the Prince William Sound region. Knowledge of ongoing landslide movement is essential to understanding the threat posed by the landslides. Because of the landslides' remote location, field-based ground monitoring is challenging. Alternatively, periodic acquisition and interferometric processing of satellite-based synthetic aperture radar data provide an accurate means to remotely monitor landslide movement. Interferometric synthetic aperture radar (InSAR) uses two Synthetic Aperture...
These data are a summary of modeled exposure of various lifeline infrastructure linear features and facilities (transportation, water supply and wastewater, oil and gas, electric power, and telecommunications) to potential hazards resulting from the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. Existing hazard data (surface offset, ground shaking (mainshock and aftershocks), landslide, liquefaction, and fire following earthquake) were looked at alone and in combination with each other relative to the lifeline infrastructure linear features and facilities to provide estimates of potential exposure to various...

This data set provides a polygon shapefile delineating relatively large, slow-moving (4-17 cm/year in the radar line-of-sight direction) landslides in the continental U.S. western coastal states (California, Oregon, and Washington). The polygons also are provided in a Google Earth .kmz file. Delineated landslides were identified from displacement signals captured by InSAR (Interferometric Synthetic Aperture Radar) interferograms of ALOS PALSAR (Advanced Land Observing Satellite; Phased Array type L-band Synthetic Aperture Radar) images between 2007 and 2011, and ALOS-2 PALSAR-2 images between 2015 and 2019. The ALOS PALSAR images utilized cover the three states entirely; the ALOS-2 PALSAR images utilized cover primarily...

Album caption: Flow failure down a hillside slope on the Nunez Ranch 4 miles (6.4 km) east of Half Moon Bay. Note the man standing at the base of the deposited debris and a second man standing on the lower edge of the cavity at the top of the slide. Additional incipient flow failures with much smaller movements also occurred on the convex hill to the left of the principal landslide. Photograph previously published in Lawson and others (1908, pl. 133B) with caption "Earth-flow 4 miles east of Half Moon Bay." San Mateo County, California. 1906. Published as figure 22 in U. S. Geological Survey Professional paper 993. 1978. (Not available from U.S.G.S. Photo Library. Photograph by R. A. Anderson, J.C. Branner...

Landslides are damaging and deadly, and they occur in every U.S. state. However, our current ability to understand landslide hazards at the national scale is limited, in part because spatial data on landslide occurrence across the U.S. varies greatly in quality, accessibility, and extent. Landslide inventories are typically collected and maintained by different agencies and institutions, usually within specific jurisdictional boundaries, and often with varied objectives and information attributes or even in disparate formats. The purpose of this data release is to provide an openly accessible, centralized map of existing information on landslide occurrence across the entire U.S. The data release includes digital...
The data in this data release are comprised of one geospatial vector dataset and three tabular datasets related to the HayWired earthquake scenario, a magnitude 7.0 earthquake hypothesized to occur on April 18, 2018, with an epicenter in the city of Oakland, CA. The geospatial vector data are a representation of identified economic subareas for use in selected analyses related to selected counties in and around the San Francisco Bay region in California. Census tracts in seven economic subareas were identified, as was whether a tract potentially has a high concentration of building stock extensively or completely damaged by (1) earthquake hazards (ground shaking, landslide, liquefaction) and (2) all hazards (ground...

Subaerial landslides at the head of the Barry Arm fjord remain a tsunami threat for the Prince William Sound region in southern Alaska. Tasked RADARSAT-2 synthetic aperture radar (SAR) data from two ultrafine beam modes (2 m), U19 and U15, were used to measure landslide movement of slopes near the toe of the Barry Glacier between 21 May 2021 and 5 November 2021. Data were acquired every 24 days, with U19 beginning on 21 May 2021 and U15 beginning on 28 May 2021. For a few planned acquisition dates, scenes were not captured because of technical issues. Interferometric synthetic aperture radar (InSAR) deformation maps (interferograms) are provided in wrapped phase (line-of-sight (LOS) phase in radians between 0 and...

On January 5, 2013, the massive landslide took out a football field-sized portion of Newfound Gap Road (US 441) on the North Carolina side. Approximately 90,000 cubic yards of dirt, rock and roadway crashed 45-50 feet down the side of the mountain. Officials from the Great Smoky Mountains National Park found a subsurface spring underneath the landslide. NPS staff said the spring, along with last week's massive amounts of rainfall, contributed to the landslide Wednesday morning, near mile marker 22 between Collins Creek and Webb Overlook.
