Data Release for 2018 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes

We produce the USGS 2018 one-year probabilistic seismic hazard forecast for the central and eastern United States from induced and natural earthquakes. For consistency, the updated 2018 forecast is developed using the same probabilistic seismicity-based methodology as applied in the two previous forecasts for 2016 and 2017. Rates of earthquakes across the U.S. (M ≥ 3.0) grew rapidly between

Classified point cloud data from the 2005 B4 Lidar Project, southern California

This data set is derived from the original 2005 data collected over the southern San Andreas and San Jacinto fault zones in southern California, USA. These data have provided a fundamental resource for study of active faulting in southern California since they were released in 2005. However, these data were not classified in a manner that allowed for easy differentiation between bare ground surfac

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 neodymium rare ear

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 conditions: i

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 included

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 relocated the maj

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 characteristi

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 velocity (Vs

2017 Valparaiso, Chile earthquake data

In April 2017, a sequence of earthquakes offshore Valparaso, Chile, raised concerns of a potential megathrust earthquake in the near future. The largest event in the 2017 sequence was a M6.9 on April 24th, seemingly co-located with the last great-sized earthquake in the regiona M8.0 in March 1985. The history of large earthquakes in this region shows significant variation in rupture size and exten

Terrestrial laser scanner data from the 2011 Horseshoe Two fire, Chiricahua Mountains, southeastern Arizona

Point cloud data collected on a steep, severely burned hillslope below Barfoot Peak near Rustler Park in the Chiricahua Mountains, AZ. The data were collected June 21, July 18, August 1, August 23, 2011 and March 14, 2012. The data were collected with a Leica Scanstation C10 High Definition Scanner. The data are delivered as georeferenced (WGS UTM zone 12N ellipsoid) and classified point clouds. T

Aftershock Catalog for the November 2011 Prague, Oklahoma Earthquake Sequence

The dataset contains the catalog of 5446 events and arrival times resulting from subspace detection processing and relocation in the for the 2011 Prague, Oklahoma, aftershock sequence. Lines beginning with "E" contain event information in the following order: event ID, origin year, origin month, origin day, origin hour, origin minute, origin second, latitude, longitude, depth, and magnitude. Lines

Main Terrace vertical offset data for the Lower Rhine Graben, central Europe - Data Release

This data release includes vertical offset information for the regionally extensive Main Terrace in the Lower Rhine Graben in the border region between Germany, Beligum, and Netherlands. These data are used in an investigation exploring the temporal and spatial pattern of Quaternary fault slip rates in this region and are the subject of an investigation by Gold and others (in review at Bulletin of
