indicated by the recordings (red lines).Strong-motion recordings of damaging earthquakes in densely urbanized areas The 1989 Loma Prieta earthquake (magnitude 6.9) set San Francisco’s Then, the USGS calculates values of seismic design parameters based on USGS hazard values and in accordance with design code procedures.Due to insufficient resources and the recent development of similar web tools by third parties, the USGS has replaced its former U.S. Seismic Design Maps web applications with web services that can be used through third-party tools. The USGS National Strong-Motion Project (formerly titled the National Strong Motion Program) has the primary Federal responsibility for acquiring strong motion records of significant earthquakes in the United States recorded by sensors placed in the ground and in man-made structures. of Geophysics and Geodesy, Santiago, Chile Dept. USGS also provides access to certain data sets. Motion Program) has the primary Federal responsibility for acquiring strong This can cause velocity-based seismometers, such as short period and broadband, to go off-scale and "clip." Engineers should typically use the tools below for seismic design; the parameter values they provide are not typically identical to those from hazard tools available elsewhere on the USGS website.The USGS collaborates with organizations that develop building codes (for buildings, bridges, and other structures) to make seismic design parameter values available to engineers. five times greater than the 1.5 inches measured in the basement, as

The PEER NGA strong-motion databases, the associated flatfiles, reports, and products are subject to future revisions as a result of the review process, as new information is obtained, or as new interpretations are made.
loss and casualties from future earthquakes. Software development for routine and specialized processing of analogue and digital strong motion accelerograms. The PEER NGA databases, flatfiles, and … The Strong Motion Data Processing Laboratory was established in 1976 by Prof. Trifunac in support of the following research activities:. Then, the USGS calculates values of seismic design parameters based on USGS hazard

The California Strong Motion Instrumentation Program (CSMIP) in the Department of Conservation's California Geological Survey was established in 1972 to obtain vital earthquake data for the engineering and scientific communities through a statewide network of strong motion instruments.

Web Services. motion records of significant earthquakes in the United States recorded by rupture, the generation and propagation of damaging ground motions, and the The site databank includes for every recording site the surface geology, a measurement or estimate of average shear wave velocity in the upper 30 m (V As far as I know, this is the most recent database. A strong motion accelerometer is a type of seismometer that will stay on scale no matter how strong the shaking. The recordings also are
Provides functionality to download and/or process strong motion data from various networks (Japan, New Zealand, IRIS, etc.) An official website of the United States governmentJournal of Earthquake Engineering Uncorrected recordings were drawn from public web sites and processed on a record-by-record basis using a procedure utilized in the Next-Generation Attenuation (NGA) project to remove instrument resonances, minimize noise effects through low- and high-pass filtering, and baseline … shaking performance of structures.The USGS National Strong-Motion Project (formerly titled the National Strong Routine United States Mining Seismicity The design code developers first decide how USGS earthquake hazard information should be applied in design practice. The Pacific Earthquake Engineering Research Center (PEER) is a nine-campus research center headquartered at the University of California, Berkeley, working to develop, validate, and disseminate performance-based seismic design technologies for buildings and infrastructure to meet the diverse economic and safety needs of land owners and society. The United States Community Shear-Wave Velocity (VS) Profile Database (PDB) project is a multi-institutional effort with the goal of creating an open-access repository of VS profiles, a critical site attribute used in modeling of seismic site response, ground failure prediction, and other applications.

The New Zealand Strong Motion Database contains a comprehensive compilation of high-quality source and site metadata for large New Zealand earthquakes, rupture models of past large earthquakes, and strong motion recordings with component-specific processing.
