Data from Earthquake-Induced Landslide Hazards for a M7.0 Scenario Earthquake on the Hayward Fault

The seismic-landslide probability map covers the counties of Alameda, Contra Costa, Marin, Napa, San Francisco, San Mateo, Santa Clara, Santa Cruz, Solano, and Sonoma. The slope failures are triggered by a hypothetical earthquake with a moment magnitude of 7.0 occurring on April 18, 2018, at 4:18 p.m. on the Hayward Fault in the east bay part of California’s San Francisco Bay region.

Flood Inundation Mapping in North and South Carolina

The U.S. Geological Survey (USGS) has created flood-inundation maps for selected streamgage sites in North and South Carolina. These maps depict the approximate area that would be inundated at selected water levels, ranging from approximately top-of-bank to a selected maximum water level.

Hazard Exposure Reporting and Analytics (HERA)

The Hazard Exposure Reporting and Analytics (HERA) application was developed to provide users with insight on potential population, economic, land cover, and infrastructure vulnerability resulting from a given hazard. Interactive maps and graphics allow users to examine hazard exposure for individual communities, to compare exposure for multiple communities and changes in hazard exposure.

FishVis Mapper

The FishVis Mapper is the product of an Upper Midwest and Great Lakes LCC project, “A Regional Decision Support Tool for Identifying Vulnerabilities of Riverine Habitat and Fishes to Climate Change” that developed an approach for predicting fish species occurrence under current climate conditions and project how fish species occurrence may change under future climate conditions.

New York Nowcast Beach Status

New York Nowcast predicts water quality conditions at select beach swimming areas in NY. The Nowcast estimates conditions by merging environment and climate data with variables measured at a beach by 8 AM each morning and entering them into a computer program which provides a probability from 1 to 100 as to whether or not the beach has exceeded the bathing-water standard of 235 units of E. coli.
