gov.noaa.ngdc.mgg.photos:15A magnitude 7.7 earthquake occurred in the Gilan Province between the towns of Rudbar and Manjil in northern Iran on Thursday, June 21, 1990 (June 20 at 21:00 GMT). The event, the largest ever to be recorded in that part of the Caspian Sea region, may have been composed of two or more closely-spaced earthquakes occurring in rapid succession. These quakes, exceptionally close to the surface for this region, were also unusually destructive.To provide long-term scientific data stewardship for the Nation's geophysical data, ensuring quality, integrity, and accessibilityIn workasNeeded49.40949.40936.95736.957NASA/GCMD Earth Science KeywordsEARTH SCIENCE > HUMAN DIMENSIONS > Natural Hazards > Geological HazardsRestriction Code: otherRestrictions; DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of CommerceHazards Dataphysical and mailing NOAA/NESDIS/NGDC E/GC 325 Broadway BoulderCO80305-3328(303) 497-3707haz.info@noaa.govUnknown 20120222Heather McCulloughDOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commercemailing and physical NOAA/NESDIS/NGDC/MGG 325 Broadway E/GC3 BoulderCO80305-3328(303) 497-3707haz.info@noaa.govHeather.McCullough@noaa.govContent Standard for Digital Geospatial Metadata: Extensions for Remote Sensing MetadataFGDC-STD-012-2002
