Develop uniformly processed ground-motion data sets leveraging data from a variety of sources for use in development and analysis of ground-motion prediction equations, shaking duration, site response, testing of earthquake early warning algorithms, and testing seismic velocity models.
of Geophysics and Geodesy, Santiago, Chile Dept. A process of validation was undertaken by the SCEC UGMS Committee to vet the MCE R response spectra generated from ground motions computed using 3D numerical ground-motion simulations (SCEC CyberShake) and the latest empirical ground-motion prediction equations (PEER NGAWest2). arrows) recorded horizontal movement on the 49th floor of the building The web-based Pacific Earthquake Engineering Research Center (PEER) ground motion database provides tools for searching, selecting and downloading ground motion data.
The next update of the NSHM for the conterminous U.S. (CONUS) will be in 2023. shaking performance of structures.The USGS National Strong-Motion Project (formerly titled the National Strong are critical for designing earthquake-resistant structures to reduce property fundamental for understanding and characterizing the physics of earthquake The design code developers first decide how USGS earthquake hazard information should be applied in design practice. five times greater than the 1.5 inches measured in the basement, as loss and casualties from future earthquakes. The USGS requests that the earthquake hazard community bring to our attention new earthquake source and ground motion data or models that could be included in the National Seismic Hazard Model (NSHM) updates. Please do not use this tool to obtain ground motion parameter values for the design code reference documents covered by the U.S. Seismic Design Maps web tools (e.g., the International Building Code and the ASCE 7 or 41 Standard). motion records of significant earthquakes in the United States recorded by Currently the NSMP operates and maintains strong-motion instruments at more than 660 ground, free-field and reference sites, and more than 3200 channels of data … 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. This is a project designed to provide a number of functions … of Natural Resources, Wash. Dept. 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. In addition, workshops are held for feedback and comments. 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. of Technology Centro de Investigaciones Geotechnicas, El Salvador Dept. rupture, the generation and propagation of damaging ground motions, and the of Water and Power, Los Angeles, Calif. Introduction. Fourteen specific sites were selected throughout the Los Angeles region for … The USGS collaborates with organizations that develop building codes (for buildings, bridges, and other structures) to make seismic design parameter values available to engineers. The 1989 Loma Prieta earthquake (magnitude 6.9) set San Francisco’s The values returned by the two applications are not identical. 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 recordings also are indicated by the recordings (red lines).Strong-motion recordings of damaging earthquakes in densely urbanized areas Web-based Data Access Tool.

Your options for using the replacement USGS web services, which still provide seismic design paramter values from numerous design code editions, are:Most users obtain seismic design parameter values from the USGS web services through third-party GUIs like the following:It is possible, but less convenient, to obtain seismic design parameter values directly from the USGS web services:This web tool calculates risk-targeted ground motion values from probabilistic seismic hazard curves in accordance with the site-specific ground motion procedures defined in “Method 2” (Section 21.2.1.2) of the Seismic design maps from various design code reference documents are available below as PDF files. ALL downloaded records are UNSCALED and as-recorded (UNROTATED).
