Data Release for the 2016 East Bay Seismic Imaging Investigation of the Hayward Fault Zone In October 2016, we acquired an approximately 15-km-long seismic profile along a linear transect across the East Bay region of the San Francisco Bay area. Our goal was to image previously unknown strands of the Hayward Fault zone and to better delineate the structure and geometry of the main trace of the Hayward Fault. Our profile started near the southern border of San Leandro, California at the San Francisco Bay shoreline, trended ENE through the northern edge of Castro Valley, California, and ended approximately 5 km WSW of San Ramon, California. The data were analyzed using refraction tomography modeling, reflection processing, and guided-wave analysis. The analyzed data are presented in separate reports by...

These data for telecommunications demand served are derived from residual network capacity based on potential hazard information (for example, ground shaking and liquefaction), assumptions about dependence on electric power restoration, and assumptions about network congestion caused by demand surge. Various resilience cases pertain to assumptions about the presence of backup power (for example, batteries or generators), ability to truck in fuel and...

The geospatial vector data are a representation of identified economic subareas for use in selected analyses related to selected counties in and around the San Francisco Bay region in California. Census tracts in seven economic subareas were identified, as was whether a tract potentially has a high concentration of building stock extensively or completely damaged by (1) earthquake hazards (ground shaking, landslide, liquefaction) and (2) all hazards (ground...

These data take information about prevailing conditions (for example, average wind speed and direction) and potential hazard information (for example, ground shaking and liquefaction) and model the resulting fire-based damages which could occur following the HayWired scenario mainshock. The results are presented as a series of Voronoi polygons centered on known fire stations in the region. This vector .SHP dataset was developed and intended for use in GIS applications...

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 extent for the HayWired mainshock ShakeMap (available at https://earthquake.usgs.gov/scenarios/eventpage/ushaywiredm7.05_se#shakemap). The sequence is simulated based on several known statistical relationships and generated using an epidemic type aftershock sequence (ETAS) model, resulting in one possible aftershock sequence....

The HayWired earthquake scenario is a magnitude 7.0 earthquake hypothesized to occur on the Hayward Fault on April 18, 2018, with an epicenter in the city of Oakland, CA. The estimates contained in this dataset are a subset of the many results products generated by FEMA's Hazus-MH 2.1 application, and reflect potential damage due to the HayWired earthquake scenario mainshock and its aftershocks....

These geophysical surveys utilized both active- and passive-source methods wherever site conditions allowed. Primary focus was on characterization of seismic stations. Major regions surveyed include the San Francisco Bay Area, Anza Valley, Imperial Valley, Los Angeles, and Santa Barbara. Also characterized were 4 PG&E dams. Active-source methods were designed for Rayleigh-wave MASW analysis, while passive-source methods were designed for use with ESAC analysis approach. Also included in this data release are data sets for geophysical surveys of five seismic stations done by standard approach surface-wave...

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. The approach of Holzer, Noce, and Bennett (U.S. Geological Survey) was used to produce the data; Holzer, Noce, and Bennett used the liquefaction potential index parameter as an indicator for liquefaction hazard in their mapping of a smaller part of northern Santa Clara County and western Alameda County.
