    • Gridded risk-targeted spectral response acceleration data and 84th-percentile spectral acceleration data used to calculate the Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations of the 2020 NEHRP Recommended Seismic Provisions, and 2022 ASCE/SEI 7 Standard for Guam and the Northern Mariana Islands.

    Metadata Updated: December 10, 2025

    The Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations of the 2020 NEHRP Recommended Seismic Provisions and 2022 ASCE/SEI 7 Standard are derived from the downloadable data files. For each spectral period and site class, the MCER spectral response acceleration (S_aM) is calculated via the following equation: S_aM = min[ S_aRT , max( S_a84th , S_aDLL ) ] where S_aRT = risk-targeted spectral acceleration S_a84th = 84th-percentile spectral acceleration S_aDLL = deterministic lower limit spectral acceleration
