Synthetic Ground Motion Data for Finite Source Inversion Blind Tests in the Marmara Area for FP7 MARSite project

This page is for the purpose of sharing the synthetic data for various earthquake scenarios in the Sea of Marmara (MARSite project - WP5). We are working on the ground motion simulations around the Sea of Marmara, including the region of Istanbul, over a dimension of 200 km (East-West) x 120 km (North-South).
This work is progressing with the GFZ (Germany) team, in particular. If someone else is interested, please contact me.


Figure 1: Map of model area (black frame) with a dimension of 200 km (EW) x 120 km (NS) x 40 km (depth). The receiver positions implemented in the simulations (open circle : Broadband statoin operated by KOERI, triangles : Strong Motion stations operated by KOERI). Small dots show the seismicity (Mw > 3) from the KOERI catalogue. Besiders these receiver points, the synthetic seismograms are recorded at thousands structured grid points (top-right panel) in order to provide the ground motion map.
