To gain insight into the underlying dynamics and aid eruption response, we applied waveform-based earthquake detection and double-difference location as the eruption unfolded. Here, we augment these rapid results by grouping events based on patterns of correlation-derived phase polarities across the network.  From April 29 to August 6, bracketing the eruption, we used ~2800 events cataloged by the Hawaiian Volcano Observatory to detect and precisely locate 44,000+ earthquakes.  Resulting hypocentroids resolve complex, yet coherent structures, concentrated at shallow depths east of Halema\u2018uma\u2018u crater, beneath the eventual eastern perimeter of surface collapse.  Based on a preponderance of dilatational P-wave first motions and similarities with previously inferred dike structures, we hypothesize that failure was dominated by coupled shear and crack closure.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9DMIFMW", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5e0f934ee4b0b207aa155342.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5e0f934ee4b0b207aa155342", "keyword": ["Kilauea", "Kilauea Crater", "USGS:5e0f934ee4b0b207aa155342", "biota", "earthquake occurrences", "volcanology"], "modified": "2020-08-18T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-180.0, -90.0, 180.0, 90.0", "theme": ["geospatial"], "title": "High resolution earthquake catalogs from the 2018 Kilauea eruption sequence"}
