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
Data from Earthquake-Induced Landslide Hazards for a M7.0 Scenario Earthquake on the Hayward Fault
These maps show the potential of widespread slope failures, in terms of landslide probabilities and displacement, triggered by a M7.0 scenario earthquake on the Hayward Fault in the 10-county area surrounding the San Francisco Bay region, California. The likelihood of landsliding was evaluated using an equation developed by Jibson and others (2000) that estimates landslide probability as a functio
Terrestrial laser scanner data from Hetch Hetchy area, Yosemite National Park, California, USA
These data are 3D point cloud data collected by laser scanner in the Hetch Hetchy area of Yosemite National Park, USA. The data were collected to assess landscape change and vegetation response following the 2013 Rim wildfire. Filename convention: "hh_datatype_dd_ddmmyyyy_laserreturns_siteidentification". "datatype" is either "alsm" or "tls" The former was collected by the National Center for Airb
Database of earthquake ground motions from 3-D simulations on the Salt Lake City of the Wasatch fault zone, Utah
This dataset consists of the processed ground motions from 96 earthquake rupture scenarios for M7 earthquakes on the Salt Lake City segment of the Wasatch fault. Details about the simulation method, ground motion variability and sensitivity of the ground motions to the kinematic rupture parameters are described in the accompanying manuscript. Simulated data is distributed as 5-percent damped respo
Liquefaction potential as a result of HayWired earthquake scenario mainshock (April 18, 2018) shaking in Alameda and Santa Clara counties, San Francisco Bay area, California
These data are a geospatial representation of liquefaction potential for the HayWired earthquake scenario, a magnitude 7.0 earthquake occurring on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. These data are the product of an analysis that created a detailed liquefaction probability map covering the northern Santa Clara County and western Alameda County areas.
Point locations for earthquakes M2.5 and greater in a two-year aftershock sequence resulting from the HayWired scenario earthquake mainshock (4/18/2018) in the San Francisco Bay area, California
This dataset represents the spatial locations of all modeled aftershocks magnitude 2.5 and greater resulting from the HayWired M7.0 mainshock occurring on April 18, 2018 along the Hayward Fault. The date/time, horizontal and vertical location, and sequence position is provided for each aftershock. The spatial extent covers 24 counties in whole or in part, corresponding to the modeled shaking exten
2017 One-Year Seismic Hazard Forecast for the Central and Eastern United States from Induced and Natural Earthquakes
We produced a one-year 2017 seismic hazard forecast for the central and eastern United States from induced and natural earthquakes that replaces the one-year 2016 forecast, and evaluated the 2016 seismic hazard forecast to improve future assessments. The 2016 forecast indicated high seismic hazard (greater than 1% probability of damaging ground shaking in 1 year) in portions of Oklahoma/Kansas, th
Earthquake catalogs for the 2017 Central and Eastern U.S. short-term seismic hazard model
The U. S. Geological Survey (USGS) makes long-term seismic hazard forecasts that are used in building codes. The hazard models usually consider only natural seismicity; non-tectonic (man-made) earthquakes are excluded because they are transitory or too small. In the past decade, however, thousands of earthquakes related to underground fluid injection have occurred in the central and eastern U.S. (
Shakemap earthquake scenario: Building Seismic Safety Council 2014 Event Set (BSSC2014)
This is a catalog of earthquake scenarios, represented as ShakeMaps. A ShakeMap is a USGS product that facilitates communication of earthquake effects by portraying a map of the severity of shaking. Maps of shaking severity are provided in terms of macroseismic intensity, peak ground acceleration, peak ground velocity, and spectral accelerations (at 0.3, 1.0 and 3 sec oscillator periods).
