Data were obtained from a variety of structural and geologic environments. Most of the data are available in three levels of processed files. The first type of file contains raw (uncorrected) time, history data points digitized from the analog accelerogram. The second is a filtered, instrument corrected version of the time, history data. This file also contains calculated velocities and displacements obtained by the integration and double integration of the corrected accelerations. The third type of file includes the calculated Fourier and response spectra data. The data are from the United States, Algeria, Argentina, Armenia, Australia, Bulgaria, Canada, Chile, China, El Salvador, Fiji, Germany, Greece, India, Iran, Italy, Japan, Mexico, New Zealand, Nicaragua, Papua New Guinea, Peru, Portugal, Romania, Spain, Taiwan, Turkey, and Uzbekistan. This database is static and is no longer being updated. purpose: Provide strong motion earthquake data for engineering research status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) individualName: Nicolas Arcos organisationName: DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (303) 497-3158 facsimile: (303) 497-6513 address: (CI_Address) deliveryPoint: 325 Broadway, Mail Code E/NE42 city: Boulder administrativeArea: CO postalCode: 80305-3328 country: USA electronicMailAddress: haz.info@noaa.gov role: (CI_RoleCode) pointOfContact resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) notPlanned maintenanceNote: There are no plans to update the data in this collection. graphicOverview: (MD_BrowseGraphic) fileName: https://www.ngdc.noaa.gov/hazard/img/accel.gif fileDescription: Accelerograph image of the Imperial Valley Aftershock May 19, 1940 at El Centro, California. fileType: jpg descriptiveKeywords: (MD_Keywords) keyword: Earth Science > Solid Earth > Seismology > Earthquake Dynamics keyword: Earth Science > Solid Earth > Seismology > Earthquake Occurrences type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science Keywords date: (CI_Date) date: 2024 dateType: (CI_DateTypeCode) revision edition: 19 citedResponsibleParty: (CI_ResponsibleParty) organisationName: Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) contactInfo: (CI_Contact) onlineResource: (CI_OnlineResource) linkage: https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords name: GCMD Keyword Forum Page description: Global Change Master Directory (GCMD). 2024.

The term "uncorrected" indicates that a digitized or digitally recorded time series has received no processing that involves any hypotheses as to the character or frequency content of the ground motions or recording instruments. An "uncorrected" analog-recorded time series has been corrected only for uneven film transport with time, for transverse motion of the film as it moved longitudinally through the recorder, and for angular tilts between the baselines of adjacent scan segments of long records. Time series derived from both analog and digitally recorded data have been shifted to have zero mean; and have been converted from digitization units or volts to units of cm/sec/sec (ordinates) and seconds (abscissas). units: UnitDefinition: identifier: cm/sec2 name: cm/sec2 dimension: (MD_Band) sequenceIdentifier: MemberName: aName: Corrected Acceleration attributeType: (unknown) descriptor: The peak corrected acceleration value in cm/sec2.

For analog data and some of the digitally recorded data, the velocity time series are derived by integrating the corrected acceleration time series. For some digitally recorded data, the velocity is derived by integrating the baseline-corrected but unfiltered acceleration time series and then filtering the velocity. units: UnitDefinition: identifier: cm/sec name: cm/sec dimension: (MD_Band) sequenceIdentifier: MemberName: aName: Maximum Displacement attributeType: (unknown) descriptor: The maximum displacement in cm. For analog data and some of the digitally recorded data, the displacement time series are derived by integrating the velocity time series. For some of the digitally recorded data, the displacement time series are derived by doubly integrating the baseline-corrected but unfiltered acceleration time series and then filtering the displacement. units: UnitDefinition: identifier: centimeter name: centimeter return to top contentInfo: (MI_CoverageDescription) attributeDescription: RecordType: Tape Files contentType: (MD_CoverageContentTypeCode) referenceInformation dimension: (MD_Band) sequenceIdentifier: MemberName: aName: Uncorrected Tape attributeType: (unknown) descriptor: All of the digitized strong motion data are arranged into sets grouped by either triggering events or geographic regions.
