Gridded uniform hazard peak ground acceleration data and 84th-percentile peak ground acceleration data used to calculate the Maximum Considered Earthquake Geometric Mean (MCEG) peak ground acceleration (PGA) values of the 2020 NEHRP Recommended Seismic Provisions and 2022 ASCE/SEI 7 Standard for Alaska.
The Maximum Considered Earthquake Geometric Mean (MCEG) peak ground acceleration (PGA) values of the 2020 NEHRP Recommended Seismic Provisions and 2022 ASCE/SEI 7 Standard are derived from the downloadable data files. For each site class, the MCEG peak ground acceleration (PGA_M) is calculated via the following equation:
PGA_M = min[ PGA_MUH, max( PGA_M84th , PGA_MDLL ) ]
where
PGA_MUH = uniform-hazard peak ground acceleration
PGA_M84th = 84th-percentile peak ground acceleration
PGA_MDLL = deterministic lower limit spectral acceleration
