Model input and output data covering Lares Municipio, Utuado Municipio, and Naranjito Municipio, Puerto Rico, for landslide initiation susceptibility assessment after Hurricane Maria Model input and output data covering Lares Municipio, Utuado Municipio, and Naranjito Municipio, Puerto Rico, for landslide initiation susceptibility assessment after Hurricane Maria
Hurricane Maria induced about 70,000 landslides throughout Puerto Rico, USA (Hughes and others, 2019). Data in this project pertain to two areas situated in Puerto Rico’s rugged Cordillera Central range. Combined, these areas account for more than half of the hurricane-induced landslides. One of these areas encloses two neighboring municipalities, Lares Municipio, and Utuado Municipio...
GPS monitoring data from spider units on the post-disaster 2014 Oso landslide, Snohomish County, Washington GPS monitoring data from spider units on the post-disaster 2014 Oso landslide, Snohomish County, Washington
Data in this release record ground-surface positions obtained during post-disaster emergency response following the 2014 catastrophic Oso (SR 530) landslide, Snohomish County, Washington. Global Positioning System (GPS) data were collected using three USGS GPS-seismometer spider units deployed adjacent to (OSO1), upslope of (OSO2), and on (OSO3) the landslide (see image for locations)...
Survey monument positions for the Cleveland Corral landslide near U.S. Highway 50, El Dorado County, California (ver. 2.0, December 2024) Survey monument positions for the Cleveland Corral landslide near U.S. Highway 50, El Dorado County, California (ver. 2.0, December 2024)
Data in this document record the ground-surface positions from 1996 to 2018 of monuments located on different kinematic elements of the Cleveland Corral landslide, or on nearby more stable ground. Data were collected about once a year in campaign mode, at times when the landslide was dormant and not moving (typically late spring or fall). Survey timing was selected to identify wet-season...
Data from ring shear strength testing of glaciolacustrine silty clay from the 2014, Oso, Washington landslide Data from ring shear strength testing of glaciolacustrine silty clay from the 2014, Oso, Washington landslide
We performed ring shear strength testing of three specimens from a glaciolacustrine silty clay unit involved in a large landslide that occurred March 22, 2014 near the town of Oso, Washington. Ring shear tests utilized apparatus DPRI-5 at Kyoto University, Japan and test results are presented herein. We refer to the specimens as the clay, clayey silt, and silt. Some tests were performed...

Enhanced landslide mobility by basal liquefaction: the 2014 SR530 (Oso), Washington landslide Enhanced landslide mobility by basal liquefaction: the 2014 SR530 (Oso), Washington landslide
Landslide mobility can vastly amplify the consequences of slope failure. As a compelling example, the March 22, 2014 landslide near Oso, Washington (USA) was particularly devastating, traveling across a 1-km+ wide river valley, killing 43 people, destroying dozens of homes, and temporarily closing a well-traveled highway. To resolve causes for the landslide’s behavior and mobility, we...

When volcanoes fall down—Catastrophic collapse and debris avalanches When volcanoes fall down—Catastrophic collapse and debris avalanches
Despite their seeming permanence, volcanoes are prone to catastrophic collapse that can affect vast areas in a matter of minutes. Large collapses begin as gigantic landslides that quickly transform to debris avalanches—chaotically tumbling masses of rock debris that can sweep downslope at extremely high velocities, inundating areas far beyond the volcano. Rapid burial by the debris...

Characterizing the catastrophic 2017 Mud Creek Landslide, California, using repeat Structure-from-Motion (SfM) photogrammetry Characterizing the catastrophic 2017 Mud Creek Landslide, California, using repeat Structure-from-Motion (SfM) photogrammetry
Along the rugged coast of Big Sur, California, the Mud Creek landslide failed catastrophically on May 20, 2017 and destroyed over 400 m of scenic California State Highway 1. We collected structure-from-motion (SfM) photogrammetry data using airborne platforms that, when combined with existing airborne lidar data, revealed that the area exhibited significant topographic change and...

Combining multiphase groundwater flow and slope stability models to assess stratovolcano flank collapse in the Cascade Range Combining multiphase groundwater flow and slope stability models to assess stratovolcano flank collapse in the Cascade Range
Hydrothermal alteration can create low‐permeability zones, potentially resulting in elevated pore‐fluid pressures, within a volcanic edifice. Strength reduction by rock alteration and high pore‐fluid pressures have been suggested as a mechanism for edifice flank instability. Here we combine numerical models of multiphase heat transport and groundwater flow with a slope‐stability code...

Control of landslide volume and hazard by glacial stratigraphic architecture, Northwest Washington state, USA Control of landslide volume and hazard by glacial stratigraphic architecture, Northwest Washington state, USA
Landslide volumes span many orders of magnitude, but large-volume slides tend to travel farther and consequently can pose a greater hazard. In northwest Washington State, USA, a landscape abounding with landslides big and small, the recent occurrence of the large-volume and tragically deadly State Route 530 (Oso) landslide is a stark reminder of the hazards associated with glacial...

Forecasting inundation from debris flows that grow during travel, with application to the Oregon Coast Range, USA Forecasting inundation from debris flows that grow during travel, with application to the Oregon Coast Range, USA
Many debris flows increase in volume as they travel downstream, enhancing their mobility and hazard. Volumetric growth can result from diverse physical processes, such as channel sediment entrainment, stream bank collapse, adjacent landsliding, hillslope erosion and rilling, and coalescence of multiple debris flows; incorporating these varied phenomena into physics-based debris-flow...

Using monitoring and modeling to define the hazard posed by the reactivated Ferguson rock slide, Merced Canyon, California Using monitoring and modeling to define the hazard posed by the reactivated Ferguson rock slide, Merced Canyon, California
Rapid onset natural disasters such as large landslides create a need for scientific information about the event, which is vital to ensuring public safety, restoring infrastructure, preventing additional damage, and resuming normal economic activity. At the same time, there is limited data available upon which to base reliable scientific responses. Monitoring movement and modeling runout...

Scoops3D: software to analyze 3D slope stability throughout a digital landscape Scoops3D: software to analyze 3D slope stability throughout a digital landscape
The computer program, Scoops3D, evaluates slope stability throughout a digital landscape represented by a digital elevation model (DEM). The program uses a three-dimensional (3D) method of columns approach to assess the stability of many (typically millions) potential landslides within a user-defined size range. For each potential landslide (or failure), Scoops3D assesses the stability...

Landslide mobility and hazards: implications of the 2014 Oso disaster Landslide mobility and hazards: implications of the 2014 Oso disaster
Landslides reflect landscape instability that evolves over meteorological and geological timescales, and they also pose threats to people, property, and the environment. The severity of these threats depends largely on landslide speed and travel distance, which are collectively described as landslide “mobility”. To investigate causes and effects of mobility, we focus on a disastrous...

Real-time monitoring of landslides Real-time monitoring of landslides
Landslides cause fatalities and property damage throughout the Nation. To reduce the impact from hazardous landslides, the U.S. Geological Survey develops and uses real-time and near-real-time landslide monitoring systems. Monitoring can detect when hillslopes are primed for sliding and can provide early indications of rapid, catastrophic movement. Continuous information from up-to-the...
