Data

This National Landslide Damages and Losses (NLDL) database was developed by extracting relevant U.S. landslide loss and damage information from a variety of sources and compiling it within a consistent framework and database structure. Sources of information on economic losses, fatalities, and key event characteristics include, but are not limited to U.S. Geological Survey (USGS) Open...

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 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 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...

This data release includes relative landslide hazard estimate maps for the southern Appa­lachian Mountains affected by Hurricane Helene (September 26-27, 2024) and the heavy rainfall that preceded it (September 23-26, 2024). The two modeling approaches used were adapted from existing models and were run in early October 2024 using initial precipitation estimates to produce rapid event...

1. Abstract 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

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...

Rainfall, volumetric soil-water content, video, and geophone data characterizing postfire rainfall and runoff were collected at two stations in the 2020 Calwood Fire Burn Area in Colorado. This release contains data from stations at two sites named Heil Ranch (40° 8' 43.47" N, 105° 20' 26.352" W) and Calwood (40° 9' 4.76" N, 105° 21' 20.79" W). The data presented here were collected from...

Precipitation, volumetric soil-water content, videos, and geophone data characterizing postfire debris flows were collected at the 2022 Hermit’s Peak Calf-Canyon Fire in New Mexico. This dataset contains data from June 22, 2022, to June 26, 2024. The data were obtained from a station located at 35° 42’ 28.86” N, 105° 27’ 18.03” W (geographic coordinate system). Each data type is...
