Data

This data release includes time-series data from 18 monitoring stations installed in Puerto Rico following Hurricane María in 2017, which led to over 70,000 landslides across the island (Hughes and others, 2017). The first two stations were installed in July of 2018 (Smith and others, 2020) to investigate subsurface hydrologic response to rainfall and develop a quantitative link between...

Wildfire can substantially alter the hydrologic response of watersheds to rainfall, and debris-flow activity is among the most destructive consequences of these events. To assist federal, state, and local agencies in planning for postfire hazards, the U.S. Geological Survey (USGS) conducts debris-flow hazard assessments for recent wildfires. This collection holds all postfire debris-flow...

This data release contains (1) geotechnical reports describing colluvium strength and grain size distribution, (2) hydrological monitoring data (rainfall and soil volumetric water content), and (3) shapefiles of mapped landslides, all from the Eagle Creek Burn Area in the Columbia River Gorge, Oregon. The geotechnical reports describe test results from two consolidated drained direct...

Description This data release contains a dataset of 227 postfire debris-flow volumes compiled from 34 burn areas across six states in the western United States. Specifically, it includes debris-flow volumes collected from the following fires: Arizona: 2010 Schultz, 2011 Horseshoe 2, 2011 Monument, 2011 Wallow, 2017 Frye, 2019 Museum, 2019 Woodbury, 2020 Bush, 2021 Flag, 2021 Horton, 2021...

This work integrated multiple topographic and bathymetric data sources to generate a merged topobathymetric map of Glacier Bay, Alaska (AK) and vicinity, including Icy Strait and parts of Lynn Canal. Earlier topobathymetric sources covering the Glacier Bay region were originally developed by the National Oceanic and Atmospheric Administration (NOAA) National Centers for Environmental...

This data release contains optical and radar-based remote sensing products used to assess ground failure and surface deformation triggered by the February 6, 2023, magnitude 7.8 and magnitude 7.5 Kahramanmaraş, Türkiye earthquake doublet and subsequent aftershocks. The datasets span the northern portion of the earthquake rupture zone and were produced to assist with the U.S. Geological...

This dataset contains 212 geotagged photographs documenting landslides and other ground failure triggered by the February 2023 Kahramanmaraş, Türkiye earthquake sequence. The photographs were primarily taken by USGS scientists during field reconnaissance conducted with Turkish colleagues from 10-20 June 2023. The primary objective of the reconnaissance was to identify and investigate...

Multiple subaerial landslides adjacent to Prince William Sound, Alaska (for example, Dai and others, 2020; Higman and others, 2023; Schaefer and others, 2024) pose a threat to the public because of their potential to generate ocean waves (Barnhart and others, 2021, 2022; Dai and others, 2020) that could affect towns and marine activities. One bedrock landslide on the west side of Barry...

A Catalog of Low-Frequency Earthquakes at the Southern Edge of Cascadia Subduction David R. Shelly1 1 U.S. Geological Survey, Geological Hazards Science Center, Golden, CO 80401 This catalog contains 61,441 detections from 27 low-frequency earthquake (LFE) families located in an isolated zone offset to the west from the southern edge of the main band of Cascadia tremor. The included...

This Data Release contains machine-readable files accompanying the study “Late Pleistocene kinematics of the Great Southern Puerto Rico fault zone, Puerto Rico” by Lynch et al. in Seismological Research Letters. The data release includes neotectonic mapping of fault-related features along the Great Southern Puerto Rico fault zone (GSPRFZ), and data documenting a focused site along the...

In this work, we refined and expanded the coseismic surface rupture map of the 1983 M6.9 Borah Peak earthquake coseismic rupture mapping at a scale of 1:500. While earlier work (DuRoss et al., 2019; Bello et al., 2020, 2021) used structure-from-motion (SfM) methods to construct digital elevation models (DEMs) derived from small uncrewed aerial systems (sUAS or drone) imagery, the...

This data release includes minidisk infiltration data as well as geographic data showing the location of each measurement from the Woolsey Fire, Los Angeles County, CA, USA. The Woolsey Fire burned between November 8-21, 2018. Minidisk infiltration data were obtained on November 19-21, 2018, while portions of the fire were uncontained, and prior to any rainfall. The infiltration data are...
