 Abstract

This dataset provides the Duration Metrics table for the NGA-Subduction records. Each record is identified by the NGAsubRSN key, which corresponds to the identical key in the NGA-Subduction Database (Bozorgnia et al. 2022). The structure and content of the NGA-Sub database is described in Mazzoni et al. (2021), and contributions related to source/path parameters and site parameters are presented in Contreras et al. (2021) and Ahdi et al. (2021), respectively. A comprehensive report on the database is presented by PEER (2020).

The Duration Metrics dataset contains, for each record component (H1,H2,V):

  • Total Arias Intensity

  • Time for 19 specified durations (5% … 100% of AI)

  • Duration for 19 specified durations (5%-10% … 5%-100% of AI)

  • Arias Intensity for 19 specified durations (5%-10% … 5%-100% of AI)

Arias Intensity, AA, was calculated using the following algorithm:

     for ii=2:NP
                AA(ii) = AA(ii-1)+(abs(A(ii))^2 + abs(A(ii-1))^2)*(T(ii)-T(ii-1))/2;

end

where A and T are the acceleration and time series vectors. The acceleration of the NGA time series is in units of g and the time is in units of seconds.
