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...

Three datasets were used in this exploration of Connectivity: CLIP 4.0 Greenways, CLIP 4.0 Landscape Integrity, and the Local Connectedness layer, one of the core datasets in the Nature Conservancy's Resiliency Project. Each dataset provides a slightly different aspect of Connectivity. Each one of the potential data layers was masked using the PR raster to result in a spatial data layer of values within Freshwater Forested Wetlands. Further information on these analyses can be found in the Freshwater Forested Wetlands Initial Investigation of Conservation...

The potential CT is Landscape Configuration. This layer was created for an initial investigation of potential CT's suggested at brainstorming workshops. The initial investigation entails locating available datasets to address the suggested CT as closely as possible and performing minimal analyses to determine their usefulness. The final set of CT's and their associated datasets will be chosen after targets (e.g., endpoints) are established as a threshold for achieving conservation success for that CT.

The potential Conservation Target is the connectivity of Working Lands. The Florida Greenways layer from CLIP 4.0 provides a context for Connectivity with natural habitats that provide connections between large natural areas in Florida. For additional metadata on CLIP 4.0, see the gallery of the same name in the Peninsular Florida LCC Community.

The suggested potential CT was Species Richness. Species Richness is one component of biodiversity, an important aspect of landscape conservation. Biodiversity is important for maintaining the balance of natural communities and ecosystems upon which humans also depend. Florida has a high level of species diversity and endemism but the state is experiencing threats to its natural heritage from a variety of sources. The data used in this analysis in addition to the Priority Resource layer is the Species Richness layer from the CLIP 4.0 geodatabase. The core layer of the geodatabase is from the...

For both U.S. Geological Survey streamflow-gaging stations (streamgages) and level-12 hydrologic unit code (HUC12) catchments, as defined by Crowley-Ornelas and others (2019), the 27 quantiles were estimated and tabulated in this data release.

The region is very well instrumented and seismically active at lower magnitudes, up to around M5, so the calibration analysis proceeded quite easily. Some events in the area are as deep as 70 km, but the cluster was restricted to events with depths less than 30 km. All events have depth control from near-source or local distance readings and many also have a few teleseismic depth phases that are in good agreement with those depths. The earthquakes are mainly in the central mountains but for a few events near the Adriatic coast there are some raypaths to local stations...
