PeakGroundAccelerationBreaklines
These data correspond to the National Seismic Hazard Model from the year 2014 made by the United States Geological Survey. Break lines of the peak ground acceleration zones on this map show a 2% chance of experiencing acceleration from earthquake-generated ground shaking greater than some fraction of gravity (g) over the next 50 years. (Data source: USGS. Year of data: 2014 Link: https://www.sciencebase.gov/catalog/item/5db9be62e4b06957974eb5ca)
