Seismic\u2010hazard analysis usually relies on ground\u2010motion prediction equations (GMPEs); within this framework site response is modeled statistically with simplified site parameters that include the time\u2010averaged shear\u2010wave velocity to 30\u00a0m (VS30) and basin depth parameters. Because\u00a0VS30\u00a0is not known in most locations, it must be interpolated or inferred through secondary information such as geology or topography. In this article, we analyze a subset of stations for which\u00a0VS30\u00a0has been measured to address effects of\u00a0VS30\u00a0proxies on the uncertainty in the ground motions as modeled by GMPEs. The stations we analyze also include multiple recordings, which allow us to compute the repeatable site effects (or empirical amplification factors [EAFs]) from the ground motions. Although all methods exhibit similar bias, the proxy methods only reduce the ground\u2010motion standard deviations at long periods when compared to GMPEs without a site term, whereas measured\u00a0VS30\u00a0values reduce the standard deviations at all periods. The standard deviation of the ground motions are much lower when the EAFs are used, indicating that future refinements of the site term in GMPEs have the potential to substantially reduce the overall uncertainty in the prediction of ground motions by GMPEs.", "description": "11 p.", "publisher": { "@type": "Organization", "name": "Seismological Society of America" }, "author": [ { "@type": "Person", "name": "Thompson, Eric M. emthompson@usgs.gov", "givenName": "Eric M.", "familyName": "Thompson", "email": "emthompson@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-6943-4806", "url": "https://orcid.org/0000-0002-6943-4806" }, "affiliation": [ { "@type": "Organization", "name": "Geologic Hazards Science Center", "url": "https://www.usgs.gov/centers/geologic-hazards-science-center" } ] }, { "@type": "Person", "name": "Wald, David J. wald@usgs.gov", "givenName": "David J.", "familyName": "Wald", "email": "wald@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-1454-4514", "url": "https://orcid.org/0000-0002-1454-4514" }, "affiliation": [ { "@type": "Organization", "name": "Geologic Hazards Science Center", "url": "https://www.usgs.gov/centers/geologic-hazards-science-center" } ] } ], "funder": [ { "@type": "Organization", "name": "Geologic Hazards Science Center", "url": "https://www.usgs.gov/centers/geologic-hazards-science-center" } ] }, "OpenAlex": { "abstract_inverted_index": { "Abstract": [ 0 ], "Methods": [ 2 ], "that": [ 3, 43, 219 ], "account": [ 4 ], "for": [ 5, 99 ], "site": [ 6, 34, 41, 149, 184, 224 ], "response": [ 7, 35 ], "range": [ 8 ], "in": [ 9, 73, 126, 226, 237 ], "complexity": [ 10 ], "from": [ 11, 156 ], "simple": [ 12 ], "linear": [ 13 ], "categorical": [ 14 ], "adjustment": [ 15 ], "factors": [ 16, 154 ], "to": [ 17, 49, 111, 145, 180, 231 ], "sophisticated": [ 18 ], "nonlinear": [ 19 ], "constitutive": [ 20 ], "models.": [ 21 ], "Seismic\u2010hazard": [ 22 ], "analysis": [ 23 ], "usually": [ 24 ], "relies": [ 25 ], "on": [ 26, 123 ], "ground\u2010motion": [ 27, 172 ], "prediction": [ 28, 239 ], "equations": [ 29 ], "(GMPEs);": [ 30 ], "within": [ 31 ], "this": [ 32, 91 ], "framework": [ 33 ], "is": [ 36, 70 ], "modeled": [ 37, 131 ], "statistically": [ 38 ], "with": [ 39 ], "simplified": [ 40 ], "parameters": [ 42 ], "include": [ 44, 139 ], "the": [ 45, 124, 127, 147, 157, 166, 171, 197, 207, 214, 223, 229, 234, 238 ], "time\u2010averaged": [ 46 ], "shear\u2010wave": [ 47 ], "velocity": [ 48 ], "30\u00a0m": [ 50 ], "(": [ 51 ], "V": [ 52, 64, 102, 116, 189 ], "S": [ 55, 67, 105, 119, 192 ], "30": [ 56, 68, 106, 120, 193 ], ")": [ 57 ], "and": [ 58 ], "basin": [ 59 ], "depth": [ 60 ], "parameters.": [ 61 ], "Because": [ 62 ], "not": [ 71 ], "known": [ 72 ], "most": [ 74 ], "locations,": [ 75 ], "it": [ 76 ], "must": [ 77 ], "be": [ 78 ], "interpolated": [ 79 ], "or": [ 80, 88 ], "inferred": [ 81 ], "through": [ 82 ], "secondary": [ 83 ], "information": [ 84 ], "such": [ 85 ], "as": [ 86, 130 ], "geology": [ 87 ], "topography.": [ 89 ], "In": [ 90 ], "article,": [ 92 ], "we": [ 93, 136 ], "analyze": [ 94, 137 ], "a": [ 95, 183 ], "subset": [ 96 ], "of": [ 97, 114, 206, 222, 240 ], "stations": [ 98, 135 ], "which": [ 100, 142 ], "has": [ 108 ], "been": [ 109 ], "measured": [ 110, 187 ], "address": [ 112 ], "effects": [ 113, 150 ], "proxies": [ 122 ], "uncertainty": [ 125, 236 ], "ground": [ 128, 158, 208, 241 ], "motions": [ 129, 209, 242 ], "by": [ 132, 243 ], "GMPEs.": [ 133, 244 ], "The": [ 134, 203 ], "also": [ 138 ], "multiple": [ 140 ], "recordings,": [ 141 ], "allow": [ 143 ], "us": [ 144 ], "compute": [ 146 ], "repeatable": [ 148 ], "(or": [ 151 ], "empirical": [ 152 ], "amplification": [ 153 ], "[EAFs])": [ 155 ], "motions.": [ 159 ], "Although": [ 160 ], "all": [ 161, 201 ], "methods": [ 162, 168 ], "exhibit": [ 163 ], "similar": [ 164 ], "bias,": [ 165 ], "proxy": [ 167 ], "only": [ 169 ], "reduce": [ 170, 196, 233 ], "standard": [ 173, 198, 204 ], "deviations": [ 174, 199 ], "at": [ 175, 200 ], "long": [ 176 ], "periods": [ 177 ], "when": [ 178, 213 ], "compared": [ 179 ], "GMPEs": [ 181, 227 ], "without": [ 182 ], "term,": [ 185 ], "whereas": [ 186 ], "values": [ 195 ], "periods.": [ 202 ], "deviation": [ 205 ], "are": [ 210, 216 ], "much": [ 211 ], "lower": [ 212 ], "EAFs": [ 215 ], "used,": [ 217 ], "indicating": [ 218 ], "future": [ 220 ], "refinements": [ 221 ], "term": [ 225 ], "have": [ 228 ], "potential": [ 230 ], "substantially": [ 232 ], "overall": [ 235 ] }, "apc_list": null, "apc_paid": null, "authorships": [ { "author_position": "first", "author": { "id": "https://openalex.org/A5066560515", "display_name": "Eric M.
