Basis for the determination of waveforms for the sites of dams in Switzerland – Subproject 1: Disaggregation of seismic hazard for return periods of 1000, 5000, 10000 years – Disaggregation dataset

Abstract

This dataset relates to part 1 of the project “Basis for the determination of waveforms for the sites of dams in Switzerland”, commissioned by the Swiss Federal Office of Energy (SFOE). The first part of the project deals with the disaggregation of ground shaking hazard levels for mean return periods of 1000, 5000, 10000 years and three intensity measure types: peak ground acceleration (PGA), spectral acceleration at 0.15 s period (SA(0.15s)) and 1.0 s period (SA(1.0s)). The current dataset contains the final disaggregation results produced for every geographical node of the disaggregation grid covering Switzerland; these results are also summarized by SIA 261 (2020) seismic zone. The procedure followed to obtain this dataset is described in the report “Basis for the determination of waveforms for the sites of dams in Switzerland - Subproject 1: Disaggregation of seismic hazard for return periods of 1000, 5000, 10000 years” by Bergamo et al. (2021; doi: https://doi.org/10.3929/ethz-b-000517545). The report describes also the data structure of the present dataset.
