Seismogenic Landslides, Debris Flows, and Outburst Floods in the Western United States and Canada from 1977 to 2017 Seismogenic Landslides, Debris Flows, and Outburst Floods in the Western United States and Canada from 1977 to 2017
This data release is a compilation of known landslides, debris flows, lahars, and outburst floods that generated seismic signals observable on existing seismic networks. The data release includes basic information about each event such as location, volume, area, and runout distances as well as information about seismic detections and the location of seismic data, photos, maps, GIS files...
Pre- and post-event digital elevation models generated from high-resolution stereo satellite imagery of the 2016 Lamplugh rock avalanche in Glacier Bay National Park and Preserve, Alaska Pre- and post-event digital elevation models generated from high-resolution stereo satellite imagery of the 2016 Lamplugh rock avalanche in Glacier Bay National Park and Preserve, Alaska
The use of high-resolution remotely sensed imagery can be an effective way to obtain quantitative measurements of rock-avalanche volumes and geometries in remote glaciated areas, both of which are important for an improved understanding of rock-avalanche characteristics and processes. We utilized the availability of high-resolution (~0.5 m) WorldView satellite stereo imagery to derive...
Data Release for: A Wideband Magnetoresistive Sensor for Monitoring Dynamic Fault Slip in Laboratory Fault Friction Experiments Data Release for: A Wideband Magnetoresistive Sensor for Monitoring Dynamic Fault Slip in Laboratory Fault Friction Experiments
These data are the basis of the figures in the manuscript "A Wideband magnetoresistive sensor for monitoring dynamic fault slip in laboratory fault friction experiments". That report was the result of an investigation of a non-contact, wideband method of sensing dynamic fault slip in laboratory geophysical experiments which employs an inexpensive magnetoresistive sensor, a small...
Map data of landslides triggered by the 25 April 2015 Mw 7.8 Gorkha, Nepal earthquake Map data of landslides triggered by the 25 April 2015 Mw 7.8 Gorkha, Nepal earthquake
The 25 April 2015 Mw 7.8 Gorkha earthquake and its aftershocks triggered about 25,000 landslides over an area of more than 30,000 km2 in the Greater and Lesser Himalaya of Nepal and China. In order to understand the relation among landslide location, earthquake shaking, topography, tectonic geologic and climatic setting, earthquake-triggered landslides were mapped using high-resolution (
Glass deformation experiments under hydrothermal conditions Glass deformation experiments under hydrothermal conditions
Six time-series data files are included in this release. The files contain mechanical data (described in metadata file below) collected during deformation experiments performed on obsidian gouge. A detailed description of the experiments along with the data reduction procedures are provided in the published manuscript titled Conversion of wet glass to melt at lower seismogenic zone...
Data for Systematic Observations of the Slip-pulse Properties of Large Earthquake Ruptures Data for Systematic Observations of the Slip-pulse Properties of Large Earthquake Ruptures
This data release includes geodetic time series from high-rate GPS instruments recording 4 earthquakes co-seismically in the near-field the 2010 Maule, Chile earthquake; the 2012 Nicoya, Costa Rica earthquake; the 2014 Iquique, Chile earthquake; and the 2015 Gorkha, Nepal earthquake. For each earthquake, data (sac files, 1 Hz sampling, ~2-3 minutes around the earthquake origin time) are...
Map data showing concentration of landslides caused by Hurricane Maria in Puerto Rico Map data showing concentration of landslides caused by Hurricane Maria in Puerto Rico
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...
A database of instrumentally recorded ground motion intensity measurements from induced earthquakes in Oklahoma and Kansas A database of instrumentally recorded ground motion intensity measurements from induced earthquakes in Oklahoma and Kansas
The database contains uniformly processed ground motion intensity measurements (peak horizontal ground motions and 5-percent-damped pseudospectral accelerations for oscillator periods 0.110 s). The earthquake event set includes more than 3,800 M≥3 earthquakes in Oklahoma and Kansas from January 2009 to December 2016. Ground motion time series were collected out to 500 km. We also...
Post-wildfire debris-flow monitoring data, Arroyo Seco, 2009 Station Fire, Los Angeles County, California, November 2009 to March 2010. Post-wildfire debris-flow monitoring data, Arroyo Seco, 2009 Station Fire, Los Angeles County, California, November 2009 to March 2010.
This data release includes time-series data from a monitoring site located in a small drainage basin in the Arroyo Seco watershed in Los Angeles County, CA, USA (N3788964 E389956, UTM Zone 11, NAD83). The site was established after the 2009 Station Fire and recorded a series debris flows in the first winter after the fire. The data include three types of time-series: (1) 1-minute time...
An Open Repository of Earthquake-Triggered Ground-Failure Inventories An Open Repository of Earthquake-Triggered Ground-Failure Inventories
Earthquake-triggered ground-failure, such as landsliding and liquefaction, can contribute significantly to losses, but our current ability to accurately include them in earthquake hazard analyses is limited. The development of robust and transportable models requires access to numerous inventories of ground failure triggered by earthquakes that span a broad range of terrains, shaking...
Silverado California Thermoluminescence Data Silverado California Thermoluminescence Data
This dataset represents thermoluminescence (TL) data that was obtained after a series of experiments to investigate how TL techniques can indicate the depth of soil heating. This project was attempted to ultimately predict changes in erosion properties in burned areas subject to debris flow hazards. The soil samples were obtained from an area burned by the Silverado wildfire (September...
Data Release of Vs30 Estimates Using Multiple Methods at 6 SCSN Stations Data Release of Vs30 Estimates Using Multiple Methods at 6 SCSN Stations
The dataset is consisted of travel-time records (vs30data.SCE.FINAL01_DATA.zip) in SEG2 format recorded using multi-station arrays near 6 seismographic stations located in southern California. A table in the spreadsheet (vs30data.SCE.FINAL01.xlsx) summarizes the data collection. Included in the dataset are figures showing incremental results supporting the resultant modeled shear-wave...
