ESRI Shapefile of fault rupture and ground deformation features produced by the Mw 6.0 South Napa Earthquake of August 24, 2014
Linework representing fault rupture and ground deformation features interpreted from airborne imagery, lidar, and InSAR interferograms, are combined with digitized field mapping into a single vector polyline shapefile.
Hillshade raster (55-degree azimuth, 20-degree sun angle) derived from lidar data collected after the August 24, 2014 South Napa Earthquake
Hillshade of lidar-derived, bare earth digital elevation model, with 55-degree azimuth and 20-degree sun angle, 0.25m resolution, depicting earthquake effects following the August 24, 2014 South Napa Earthquake.
Hillshade raster (235-degree azimuth, 20-degree sun angle) derived from lidar data collected after the August 24, 2014 South Napa Earthquake
Hillshade of lidar-derived, bare earth digital elevation model, with 235-degree azimuth and 20-degree sun angle, 0.25m resolution, depicting earthquake effects following the August 24, 2014 South Napa Earthquake.
Shear-wave velocity in the Seattle basin to 2 km depth characterized with the krSPAC microtremor array method: insights for urban basin-scale imaging - Data Release
The dataset for this investigation consists of microtremor array data collected at 11 sites in the Seattle basin, Washington State. Ten of the arrays consisted of seven Nanometrics Trillium Compact broadband sensors deployed in asymmetric nested triangles (sites ST01, BA02, SP04, LF05, UW06, SN07, RD08, EL09, CH10, and KG11) that recorded for up to six hours. The eleventh
2016 Mw 6.0 Petermann Ranges earthquake, Australia: Pre- and post-earthquake digital elevation models
We generated digital elevation models (DEMs) using pre- and post-event in-track stereo 0.5 m resolution panchromatic Worldview 1 and 2 images (©2019, DigitalGlobe) using the Surface Extraction from TIN-based Searchspace Minimization (SETSM) software [Noh and Howat, 2015] running on the University of Iowa Argon supercomputer (Table S1). The post-event DEMs exhibit alon
KMZ file of fault rupture and ground deformation features produced by the Mw 6.0 South Napa Earthquake of August 24, 2014
Linework representing fault rupture and ground deformation features interpreted from airborne imagery, lidar, and InSAR interferograms, are combined with digitized field mapping into a single KMZ file.
Table of locations within the West Napa Fault System where surface faulting produced by the Mw 6.0 South Napa Earthquake of August 24, 2014 was anticipated but where no evidence of ground disturbance was observed
Locations along fault trends and InSAR lineaments where surface faulting was anticipated but where no evidence of ground disturbance was observed. Each record in our Negative Evidence table constitutes a station, which is a location where an observation was made by a single investigator or a field team working together (an observer) during a single visit on particular date.
Table of field observations of fault rupture and ground deformation features following the Mw 6.0 South Napa Earthquake of August 24, 2014
This product is the result of a comprehensive compilation of site-specific field descriptions and displacement measurements where tectonic faulting and ground failure produced visible deformation that fractured and disturbed the ground surface. The resultant data is distributed as a tab-delimited text file. All post-earthquake ground rupture observations and slip/displacement measurements are...
Data for Rupture Model of the 2016 M5.8 Pawnee, Oklahoma Earthquake
The 2016 M5.8 Pawnee, Oklahoma earthquake is the largest earthquake to have been induced by wastewater disposal. We infer the coseismic slip history from analysis of apparent source time functions and inversion of regional and teleseismic P-waveforms, using aftershocks as empirical Green’s functions. The earthquake nucleated on the shallow part of the fault, initially rupturing towa
Photographs of fault rupture and ground deformation features produced by the Mw 6.0 South Napa earthquake of August 24, 2014
This product is the result of a comprehensive compilation of site-specific ground photographs taken where tectonic faulting and ground failure produced visible deformation that fractured and disturbed the ground surface. The resultant data is distributed as collection of JPEG image files. All post-earthquake photographs taken by investigators working for public agencies are in the public...
Hurricane Harvey — A Damage Assessment of Texas’ Central Gulf Coast
This data set serves as a damage scale that was created to assess the damage caused by Hurricane Harvey in August 2017. The damage scale ranges from 1 (undamaged) to 5 (total structure collapse, destroyed). A score of 1 was given to structures that had no damage, a score of 2 was given to structures with minor damage, a score of 3 was given to structures with moderate damage, a sc
Digital Surface Models for the northern 16 km of the 1983 Borah Peak earthquake rupture, northern Lost River fault zone (Idaho, USA)
We present high-resolution (10-cm pixel) digital surface models (DSMs) generated for the northern 16 km of the surface rupture associated with the 1983 Mw 6.9 Borah Peak earthquake. These DSMs were generated using Agisoft Photoscan (and Metashape) image-based modeling software and low-altitude aerial photographs acquired from unmanned aircraft systems and a tethered balloon.
