Earthquake Ground Motion
In conjunction with a companion paper by the same authors in this volume, this paper discusses the issues arising in the process of forecasting strong motion fields that need to be dealt with further. Firstly, the field must be estimated from the same source model, rather than taking the average motion at a site from more than 30 source models as in the current seismic hazard assessment practice. The second issue concerns the random synthesis, that is, the uncertainty in the envelop of motiondoi:10.2495/978-1-84566-000-0/008 fatcat:qwmixqy3rbaedobk3xogwhujna
