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.

The Aratozawa Dam landslide in Japan, was triggered by the 7.2 magnitude Iwate-Miyagi-Nariku earthquake which occurred on 14 June 2008. The landslide at the Aratozawa Dam in Kurihara measures over 1km in length and is 0.8 km wide. The landslide body mass is around 6700 million cubic meters and the amount of displacement was around 300 meters in the main section. The landslide was translational in nature and the geology comprises hard volcanic rocks overlying soft Tertiary sediments.

February 20, 2013 Bitter Spring on Highway 89 near Page, Arizona. (Photo by Arizona Department of Transportation) The Bitter Spring landslide occurred along heavily-used US Highway 89, about 25 miles south of Page, Arizona. The regional landslide complex in which the slide occurred has been recognized since at least since early last century (Gregory's 1917 USGS Professional Paper 93, "Geology of the Navajo Country"). The Arizona Dept. of Transportation (ADOT) will pave Navajo Route 20 (N20) as a detour at a cost of $28 million. Since the landslide occurred in an active landslide area, it is probable that the highway will not be rebuilt over the original route.

Hawaii Volcanoes National Park. The magnitude 6.6 earthquake on November 16, 1983, caused a landslide of sections of the north rim into Kilauea caldera. Tension cracks ate at the top of the landslide. View is to the east from the northeast rim of the caldera. Page 898, U.S. Geological Survey Professional paper 1350.

On September 20, 2017, Hurricane Maria hit the U.S. territory of Puerto Rico as a category 4 storm. Heavy rainfall caused landslides in mountainous regions throughout the territory. This data release presents geospatial data describing the concentration of landslides generated by Hurricane Maria in Puerto Rico. We used post-hurricane satellite and aerial imagery collected between September 26, 2017 and October 8, 2017 to visually estimate the concentration of landslides over nearly the whole territory. This was done by dividing the territory into a grid with 4 square km cells (2 km x 2 km). Each 4 square km grid cell was classified as either containing no landslides, fewer than 25 landslides/ square km or more than...

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. Compilations of potential collocations between various lifeline infrastructure systems components (all lifeline components, transmission-level components only, distribution-level components only, more societally critical components only, and less societally critical components only) and their potential multi-hazard exposure...

This dataset consists of over 800 field observations of ground failure (landslides, lateral spreading, and liquefaction) and other damage triggered by the 2019-2020 Puerto Rico earthquake sequence. The sequence started with a M4.7 earthquake on 28 December 2019, followed by many more earthquakes, including 15 larger than M5 (as of 7 July 2020). The M6.4 mainshock, which is thought to have triggered much of the observed ground failure, occurred on 7 January 2020. Most field reconnaissance efforts documented here took place as soon as possible after the mainshock, from 12-18 January 2020, to attempt to capture ephemeral data before evidence was destroyed by natural forces or repairs, but observations continued to...

Airborne electromagnetic (AEM) and magnetic survey data were collected during June 2012 along 556 line-kilometers over Iliamna Volcano, Alaska. These data were collected in support of alteration and volcano flank instability mapping as part of the U.S. Geological Survey (USGS) Volcano Hazards Program. Data were acquired by SkyTEM Survey ApS SkyTEM304 system with the Soloy Helicopters Eurocopter Astar 350 B3 and Bell 407 dual-moment, time-domain helicopter-borne electromagnetic system together with a Geometrics G822A cesium vapor magnetometer with Kroum KMAG4 counter. The survey was flown at a nominal flight height of 30 meters (m) above terrain along block-style lines with a nominal spacing of 250 m. The survey...
