Processed strong-motion records of engineering interest are available at the Center for Engineering Strong Motion Data (CESMD).

Vs30, the time-averaged shear-wave velocity (Vs) in the upper 30 meters, is a key index adopted by the earthquake engineering community to account for seismic site conditions. USGS has compiled measured VS30 funded by the USGS and other governmental agencies for 4389 sites in the United States.

US Geological Survey operates a streamflow monitoring network that extends across the United States and its territories. The network was analyzed systematically by Konrad and others (2022) for its coverage, resolution, and representation of a wide range of public interests in streamflow information The results can be used to identify priority areas for continued or expanded monitoring.

The USGS Ecosystems Mission Area provides science to understand wildlife diseases, including avian influenza (AI). Avian influenza viruses occur naturally in wild birds such as ducks, geese, swans, and gulls. These viruses generally do not cause illness in wild birds but they can be highly pathogenic and cause illness and death in poultry and wildlife. Learn more with this geonarrative.

Did You Feel It? (DYFI) collects information from people who felt an earthquake and creates a shaking intensity map. Visit the Web Tool to report your experience with an earthquake or to see the shaking intensity map created by the felt reports.

The Nontidal Network Mapper geonarrative is a data-driven, interactive narrative that shares the short-term water-year nutrient and suspended-sediment load and trend results for the Chesapeake Bay Program’s non-tidal network (NTN). The mapper provides the primary findings for nitrogen, phosphorus and suspended-sediment trends, and gives the user tools to further examine results.

The Hydro Mapper is an interactive map viewer which allows users to see real-time information on stream flow discharge, stage, nutrient, turbidity, sediment loads, and storage data. 

The U.S. Geological Survey (USGS) has partnered with North Carolina State University (NCSU), Louisiana State University (LSU) and University Corporation for Atmospheric Research (UCAR) to investigate hurricane-induced compound flooding and sediment dispersal using coupled hydrology and ocean models. 

ScienceBase is data and information management infrastructure that enables data upload, documentation, sharing, and dynamic data services using standards-compliant methods and technological components. ScienceBase furnishes a foundation for data stewardship, government open data, and scientific discovery.

Since 1969, the Pennsylvania Water Science Center has had a cooperative program with Chester County to measure and describe water resources. Cooperation has been primarily with the Chester County Water Resources Authority, with participation from the Chester County Health Department.

The Chester County Monitoring Network web tool provides near real-time water data.
