Assessment of Ground Motion Models: A Case Study of the Earthquake 29 May 2008 (M_w 6.3) in South Iceland

摘要

In this study an assessment is made of a ground motion model that has been developed for Iceland. For this purpose the focus will be on applying the model to ground motion records obtained in an earthquake that occurred on 29 May 2008 in the Olfus District in South Iceland. The earthquake struck at 15:45 UTC and has been estimated to have a moment magnitude M_w 6.3. The ground motion model is derived from a source model and its main purpose is to estimate ground motion for engineering purposes. The model has been applied to Icelandic earthquakes and parameters have been estimated from the data by means of inversion. In the current study the model is applied to the 29 May earthquake and an assessment is made of the fit to PGA data, from recorded ground motion, using estimated model parameters.
