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'uma'u 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.", "descriptionType": "Abstract" } ], "geoLocations": [], "fundingReferences": [], "xml": "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", "url": "https://www.sciencebase.gov/catalog/item/5dd7149de4b0695797650d0a", "contentUrl": null, "metadataVersion": 0, "schemaVersion": "http://datacite.org/schema/kernel-4", "source": "mds", "isActive": true, "state": "findable", "reason": null, "viewCount": 0, "viewsOverTime": [], "downloadCount": 0, "downloadsOverTime": [], "referenceCount": 0, "citationCount": 0, "citationsOverTime": [], "partCount": 0, "partOfCount": 0, "versionCount": 0, "versionOfCount": 0, "created": "2020-01-03T20:53:35.000Z", "registered": "2020-01-03T20:53:36.000Z", "published": "2020", "updated": "2020-12-17T17:39:39.000Z" }, "relationships": { "client": { "data": { "id": "usgs.prod", "type": "clients" } }, "provider": { "data": { "id": "pryl", "type": "providers" } }, "media": { "data": { "id": "10.5066/p9dmifmw", "type": "media" } }, "references": { "data": [] }, "citations": { "data": [] }, "parts": { "data": [] }, "partOf": { "data": [] }, "versions": { "data": [] }, "versionOf": { "data": [] } }, "type": "dois"
