 "description": "Probabilistic seismic-hazard maps were prepared for Hawaii portraying peak horizontal acceleration and horizontal spectral response acceleration for 0.2- and 1.0-second periods with probabilities of exceedance of 10 percent in 50 years and 2 percent in 50 years.  This particular data set is for horizontal spectral response acceleration for 1.0-second period  with a 2 percent probability of exceedance in 50 years.  All of the maps were prepared by combining the hazard derived from spatially smoothed historic seismicity with the hazard from fault-specific sources.  The acceleration values contoured are the random horizontal component.  The reference site condition is firm rock, defined as having an average shear-wave velocity of 760 m/sec in the top 30 meters corresponding to the boundary between NEHRP (National Earthquake Hazards Reduction program) site classes B and C.\n\nFor more information online visit:\nhttp://pubs.er.usgs.gov/publication/i2724,\nhttp://bssa.geoscienceworld.org/content/91/3/479, and \nhttp://earthquake.usgs.gov/hazards/",
