New Directions in Seismic Hazard Assessment through Focused Earth Observation in the Marmara Supersit

Long-term monitoring experiment in geologically active regions of Europe prone to natural hazards: the Supersite concept

Start: 1 November 2012
Project Coordinator: Prof.Dr. Nurcan Meral Özel, KOERI

MARsite aims to improve the seismic hazard and risk assessment for the densely populated Marmara region by long-term, multi-disciplinary monitoring activities - both on land and in the sea - related to the earthquake generation processes. GFZ will work on the following themes: Improvement of in-situ fluid measurement systems (wp2),  geodetic monitoring of crustal deformation (wp3), microseismic monitoring of the eastern Marmara seismic gap (wp4), analysis of the response of near-surface geology to earthquake ground motion and its effects on masking source-related information derived from borehole data (wp4), simulation of earthquake/tsunami scenarios for the Marmara Sea region (wp5), improvement of rapid finite source inversion tools (wp5), and the development of new procedures for the real-time estimation of the effective shaking of a building (wp9).
