Since 1939, devastating earthquakes with magnitude greater than seven ruptured North Anatolian Fault (NAF) westward, starting from 1939 Erzincan (Ms=7.9) at the eastern Turkey and including the latest 1999 Izmit-Golcuk (Ms=7.4) and the Duzce (Ms=7.2) earthquakes in the eastern Marmara Region. The only un-ruptured segments of the NAF in the last century are within the Sea of Marmara, and are identified as a "seismic gap" zone.
Istanbul with high population similar to Tokyo in Japan, is located around the Sea of Marmara where severe damages expected to be generated as compound damages including Tsunami and liquefaction, when the next destructive Marmara Earthquake occurs. It was considered that Japanese and Turkish researchers can share their own experiences during past damaging earthquakes and can prepare for the future large earthquakes in cooperation with each other. Therefore, in 2013 the two countries, Japan and Turkey made an agreement to start a multidisciplinary research project, MarDiM SATREPS.
The Project is consisting of 4 research groups with the following goals.
1)"Earthquake Source region observational research". OBS, Electromagnetic and Seafloor extensometer observations has been conducted in order to identify the detailed seismic zone, fault geometry, 3D Velocity structure and reliable crustal deformation.
2)"Tsunami prediction based on earthquake cycle simulation research" focuses on scenario earthquakes and tsunamis occurrence along the NAF and precise tsunami simulation.
3)"Seismic characterization and damage prediction research" aims improvements and constructions of seismic characterizations and damage predictions based on observation researches and precise simulations.
4)"Disaster education using research result visuals from each research". Seminars with media representatives and local authorities have been organized in order to have effective dissemination of disaster information flow.
