There may not be “a whole lot of shakin’ going on” when it comes to seismic standards, but recent ASTM updates to the Standard Guide for Seismic Risk Assessment of Buildings (E2026-16a) and the Standard Practice for Probable
Maximum Loss (PML) Evaluations for Earthquake Due-Diligence Assessments (E2557-16a) could still significantly impact you and your business.
In July, 2014, the U.S. Geologic Survey (USGS) announced that it has updated its national seismic hazard maps for the continental United States. This mapping is a graphic representation of the best and most current understanding of where future earthquakes will occur, how often they will occur, and how hard the ground will likely shake as a result (known as Peak Ground Acceleration, or PGA). According to the USGS, the new hazard maps are to be made available in late September, 2014.
