While caldera collapses happen infrequently, the collapse-related seismicity damaged nearby structures, and so these events should be included in a complete seismic hazard assessment. Here, we present an approach to forecast the seismic hazard of the collapse earthquakes. We model their occurrence by combining a Poisson distribution for the number of collapses with a negative binomial for the number of earthquakes in a collapse, based on observations at K\u012blauea. This rate model is then combined with a ground motion model to assess the seismic hazard posed by caldera collapse events. The rate model is non-Poisson but a Poisson model is adequate for low exceedance probabilities (e.g., <10% in 50\u00a0years). This approach could be generalized to model the hazard from earthquakes triggered by other underlying processes.", "description": "e2020GL092242, 9 p.", "publisher": { "@type": "Organization", "name": "American Geophysical Union" }, "author": [ { "@type": "Person", "name": "Michael, Andrew J. michael@usgs.gov", "givenName": "Andrew J.", "familyName": "Michael", "email": "michael@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-2403-5019", "url": "https://orcid.org/0000-0002-2403-5019" }, "affiliation": [ { "@type": "Organization", "name": "Earthquake Science Center", "url": "https://www.usgs.gov/centers/earthquake-science-center" }, { "@type": "Organization", "name": "Earthquake Hazards Program", "url": "https://www.usgs.gov/programs/earthquake-hazards" } ] }, { "@type": "Person", "name": "Llenos, Andrea L. allenos@usgs.gov", "givenName": "Andrea L.", "familyName": "Llenos", "email": "allenos@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-4088-6737", "url": "https://orcid.org/0000-0002-4088-6737" }, "affiliation": [ { "@type": "Organization", "name": "Earthquake Science Center", "url": "https://www.usgs.gov/centers/earthquake-science-center" } ] } ], "funder": [ { "@type": "Organization", "name": "Earthquake Science Center", "url": "https://www.usgs.gov/centers/earthquake-science-center" }, { "@type": "Organization", "name": "Geologic Hazards Science Center", "url": "https://www.usgs.gov/centers/geologic-hazards-science-center" } ], "spatialCoverage": [ { "@type": "Place", "additionalType": "country", "name": "United States", "url": "https://geonames.org/4074035" }, { "@type": "Place", "additionalType": "state", "name": "Hawaii" }, { "@type": "Place", "additionalType": "unknown", "name": "K\u012blauea volcano", "url": "https://geonames.org/5849380" }, { "@type": "Place", "geo": [ { "@type": "GeoShape", "additionalProperty": { "@type": "PropertyValue", "name": "GeoJSON", "value": { "type": "FeatureCollection", "features": [ { "type": "Feature", "properties": {}, "geometry": { "type": "Polygon", "coordinates": [ [ [ -155.41671752929688, 19.15165474470855 ], [ -155.03082275390622, 19.15165474470855 ], [ -155.03082275390622, 19.530024424775405 ], [ -155.41671752929688, 19.530024424775405 ], [ -155.41671752929688, 19.15165474470855 ] ] ] } } ] } } }, { "@type": "GeoCoordinates", "latitude": 19.34083958474198, "longitude": -155.22377014160156 } ] } ] }
