[docs]classWeatherill2024ESHM20AvgSA(KothaEtAl2020ESHM20):""" This class implements a variation of the Kotha et al (2020; 2022) GMM that was used for the ESHM20, but here the predicted intensity measure is average SA (AvgSA) rather than SA. This is a form of direct AvgSA GMM, which is fit using the same data set as that of KothaEtAl2020 with AvgSA defined according the specifications of (among others) Iacoletti et al. (2023): AvgSA = sqrt(prod([0.2 x T <= T <= 1.5 x T])) where a total of 10 linearly-spaced conditioning periods in the range are used to define the average SA. As the same regression methods were used to fit AvgSA then all of the adjustment terms adopted by the ESHM20 (sigma_mu_epsilon, c3_epsilon, ergodic etc.) can be applied to the AvgSA GMM, which allows the same logic tree to be constructed for the direct AvgSA case. Further details on the compilation and application of the GMM are being developed in the following publication (in preparation): Weatherill, G (2024) "A Regionalised Direct AvgSA Ground Motion Model for Europe", (Journal TBC) As this is in preparation, futue changes to the model are possible so we therefore retain the experimental warning, which will be removed at a future date.
