Slip deficit along Major Seismic Gaps in Turkey

Project Manager:  Asst. Prof. Dr. Fatih BULUT

Project Code: 14453

Project Start Date: 2018

Project Budget: 170 000 TL


Slip deficit and its interaction with the earthquake activity will be investigated along major seismic gaps in Turkey using inter-seismic period Global Positioning System (GPS) measurements and refined earthquake catalogues. Geodetic database consists of more than thousands of GPS stations, which are uniformly integrated. Earthquake database consists of tens of thousands of micro-earthquakes recorded by several hundreds of seismic stations operated mainly by Kandilli Observatory and Earthquake Research Institute (KOERI) and Prime Ministry Disaster and Emergency Management Authority (AFAD). In this frame, along-fault distribution of slip deficit will be compared with the micro-seismicity as well as available slip distribution models of the past M>6.0 earthquakes. Historical earthquakes will be used to verify annual slip rates of the investigated fault segments. Comparison between inter-seismic slip deficit and available co-seismic slip distribution models will verify whether GPS data can forecast slip distribution of large earthquakes. Furthermore, comparison between inter-seismic slip deficit and available refined earthquake catalog will verify creeping and locked fault patches along the fault segments, which are expected to accommodate large earthquakes in the future. Finally, developed slip deficit models will be used to forecast co-seismic slip of the expected large earthquakes.
