Of four explosions in October 2004, none had precursory \nseismicity and two had explosion-related seismic tremor that \nmarked the end of the explosion. However, seismicity levels \ndropped following each of the October explosions, providing \nthe primary instrumental means for explosion detection during the initial vent-clearing phase. In contrast, explosions on \nJanuary 16 and March 8, 2005, produced noticeable seismicity in the form of explosion-related tremor, infrasonic signals, \nand, in the case of the March 8 explosion, an increase in event \nsize ~2 hours before the explosion. In both 2005 cases seismic \ntremor appeared before any infrasonic signals and was best \nrecorded on stations located within the crater. These explosions demonstrated that reliable explosion detection at volcanoes like Mount St. Helens requires seismic stations within \n1-2 km of the vent and stations with multiple acoustic sensors.", "description": "17 p.", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Moran, Seth C. smoran@usgs.gov", "givenName": "Seth C.", "familyName": "Moran", "email": "smoran@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-7308-9649", "url": "https://orcid.org/0000-0001-7308-9649"}, "affiliation": [{"@type": "Organization", "name": "Volcano Hazards Program", "url": "https://www.usgs.gov/programs/VHP"}, {"@type": "Organization", "name": "Volcano Science Center", "url": "https://www.usgs.gov/centers/volcano-science-center"}]}, {"@type": "Person", "name": "Lockhart, Andrew B. ablock@usgs.gov", "givenName": "Andrew B.", "familyName": "Lockhart", "email": "ablock@usgs.gov"}, {"@type": "Person", "name": "McChesney, Patrick J.", "givenName": "Patrick J.", "familyName": "McChesney"}], "editor": [{"@type": "Person", "name": "Sherrod, David R. dsherrod@usgs.gov", "givenName": "David R.", "familyName": "Sherrod", "email": "dsherrod@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-9460-0434", "url": "https://orcid.org/0000-0001-9460-0434"}, "affiliation": [{"@type": "Organization", "name": "Volcano Science Center", "url": "https://www.usgs.gov/centers/volcano-science-center"}]}, {"@type": "Person", "name": "Stauffer, Peter H. pstauffe@usgs.gov", "givenName": "Peter H.", "familyName": "Stauffer", "email": "pstauffe@usgs.gov"}, {"@type": "Person", "name": "Scott, William E. wescott@usgs.gov", "givenName": "William E.", "familyName": "Scott", "email": "wescott@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-8156-979X", "url": "https://orcid.org/0000-0001-8156-979X"}, "affiliation": [{"@type": "Organization", "name": "Volcano Science Center", "url": "https://www.usgs.gov/centers/volcano-science-center"}]}], "funder": [{"@type": "Organization", "name": "Volcano Hazards Program", "url": "https://www.usgs.gov/programs/VHP"}], "spatialCoverage": [{"@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/6252001"}, {"@type": "Place", "additionalType": "state", "name": "Washington", "url": "https://geonames.org/5815135"}, {"@type": "Place", "additionalType": "unknown", "name": "Mount St. Helens"}, {"@type": "Place", "geo": [{"@type": "GeoShape", "additionalProperty": {"@type": "PropertyValue", "name": "GeoJSON", "value": {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[-122.238678, 46.161175], [-122.238678, 46.233792], [-122.131489, 46.233792], [-122.131489, 46.161175], [-122.238678, 46.161175]]]}}]}}}, {"@type": "GeoCoordinates", "latitude": 46.197483500000004, "longitude": -122.18508349999999}]}]}
