As part of a paleoliquefaction project sponsored by the U.S. Nuclear Regulatory Commission (NRC), the Central and Eastern U.S. paleoliquefaction database has been updated to include new paleoliquefaction information that has become available in the past five years. This information was collected in the Central Virginia seismic zone, the New Madrid seismic zone, and the region between the New Madrid and Wabash Valley seismic zones. In addition, new radiocarbon and optically-stimulated luminescence (OSL) databases have been created of dating results for sites listed in the paleoliquefaction database. The radiocarbon database includes results for all the regions represented in the paleoliquefaction database. The OSL database includes results for the Central Virginia seismic zones, the New Madrid seismic zones, the Marianna area south of the New Madrid seismic zone, and the region between the New Madrid and Wabash Valley seismic zones. The purposes of the databases are to compile and preserve paleoliquefaction and related dating information and to make it readily available for paleoearthquake research as well as earthquake hazard assessment. The databases are searchable, expandable, and include all large regional datasets of paleoliquefaction features and related dating results. The databases, as well as lists of references cited in the databases, are included in the final report of contract NRC-HQ-11-C-04-0041 to be published in 2019 and made available online through the U.S. NRC’s Agency-wide Documents Access and Management System.
