gov.noaa.ngdc.mgg.photos:270This dormant stratovolcano in Papua New Guinea suddenly exploded in 1951. Nu?es ardentes (glowing avalanches) shot down the mountain at 100 km per hour, devastated over 200 km2, and killed about 3,000 people. Temperatures of the cloud were so high that the deposits were still hot two years later. Following the explosive eruption, a 500-meter-high lava dome grew in the explosion crater until 1956.To provide long-term scientific data stewardship for the Nation's geophysical data, ensuring quality, integrity, and accessibilityIn workasNeeded148.17148.17-8.94-8.94NASA/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
