Frankel, Arthur D. 2012 paper Reston, VA U.S. Geological Survey https://pubs.usgs.gov/of/2012/1015/ Gridded seismic hazard curve data, gridded ground motion data, and mapped gridded ground motion values are available for the 2012 Guam and Northern Mariana Islands Seismic Hazard Model. Probabilistic seismic hazard data and maps of Guam and the Northern Mariana Islands for peak ground acceleration (PGA) and 0.2 and 1.0 second spectral acceleration at probability levels of 2 percent in 50 years (annual probability of 0.000404) and 10 percent in 50 years (annual probability of 0.0021), assuming firm rock soil conditions at 760 m/s, are available. Development of the 2012 Guam and Northern Mariana Islands Seismic Hazard Model is documented in the USGS Open-File Report 2012-1015 (https://pubs.usgs.gov/of/2012/1015/). This dataset is considered a legacy dataset. The original dataset was uploaded to the USGS website at the time of publication of the seismic hazard model (2012) but was later moved over the the USGS ScienceBase Catalog (2019). The original dataset was assumed to be complete and accurate, but may contain inconsistencies when compared to more recent, actively maintained datasets. To provide gridded hazard data and hazard maps for the 2012 Guam and Northern Mariana Islands seismic hazard model. 2012 Date model was developed Complete None planned 139.0 151.0 23.0 9.0000000000001 USGS Thesaurus USGS Geologic Hazards Science Center GHSC Earthquake Hazards Program EHP U.S. Seismic Hazard Maps National Seismic Hazard Model NSHM National Seismic Hazard Model Project NSHMP hazard curve hazard map ground motion spectral period NEHRP site classes Guam and the Northern Mariana Islands USGS Metadata Identifier USGS:5dc04f90e4b06957974ee89e Geographic Names Information System (GNIS) Guam and the Northern Mariana Islands none none Shumway, Allison M.
