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...

This data release includes aerial photos taken from a small aircraft for reconnaissance purposes (Figure 1). The photos were taken from several different types of cameras ranging from iPhones to Cannon EOS6. Camera attributes can be found in the exif data associated with each file. Photos were taken over a period of 3 days (3-5 October, 2024) to obtain general situational awareness of...

This release includes lidar point cloud and Wolman pebble count data for a debris-flow deposit in Glenwood Canyon, CO. The data, FullDepositRegion.las (las 1.2), were collected with a terrestrial laser scanner and includes the full deposit and portions of the slope and drainage that generated the debris flow. This .las file includes point cloud data up to 250 m upslope of the deposit...

This dataset contains 17 fluvial and hillslope planforms for a 2.25 km section of the Nooksack River and adjacent Clay Banks landslide complex in northwestern Washington State spanning 1933-2022. Data include polygon and line features of river and hillslope planform structures for each year including landslides, the active river channel, the floodplain corridor, and vegetated floodplain...

This data release provides shapefiles of surface rupture mapping, interferometric synthetic aperture radar (InSAR) data, finite fault modeling inputs, parameters, and outputs, and optical image cross-correlation displacement data derived from high-resolution satellite imagery to accompany the manuscript “Thompson Jobe and others, Surface Rupture From an Aftershock: Remote Observations...

This data release is a geospatial record of flooding and debris-flow activity following the 2020 Dolan Fire along the central California coast. The postfire hydrologic responses documented here (“Inventory.csv”) are associated with a January 27, 2021, atmospheric river storm that hosted a narrow cold-frontal rain band, which produced intense rainfall over the burned area. Each entry in...

An atmospheric river storm on January 9, 2023, produced widespread landsliding in the Santa Ynez Mountains in Santa Barbara County and Ventura County, California (USA). Landslides occurred in the footprint of the 2008 Tea Fire, 2009 Jesusita Fire, 2017 Thomas Fire, and 2019 Cave Fire, as well as in areas that had not burned in more than 15 years. Most of these landslides were shallow...

These are the scanned digital images of microfilm copies of paper seismic records from the World-Wide Standardized Seismographic Network (WWSSN). This data set spans from 1962 to 1978 and contains about 3.7 million single-day records, which is about 5% of the entire archive. Overall the data set contains 153 magnitude 6+ earthquakes and 156 nuclear explosions. All scans were done using...
