Variation in seismicity rate in the earthquake chronology recovered from the Dead Sea Sediments (DFT) with data from adjacent plate boundaries (EAF-NAF).
Paleoseismological and historical seismic data suggest that the activity along the North Anatolian Fault is in tandem with the Dead Sea Fault and that both alternate with the East Anatolian Fault. Alternating activity along 1000 km long boundaries over period of several hundred of years is striking. This transfer in seismic activity needs to be confirmed and would have broad implications regarding continental-scale seismic coupling.
The present project thus seeks to obtain a most extensive chronology of past events along both the North and the East Anatolian Faults. For that purpose we plan to extract a long term seismic record from lakes located along the North and East Anatolian Faults. The objective is to identify and date sedimentary structures disturbed by earthquakes, namely seismites. A similar work has been done along the Dead Sea Transform (e.g. Migowski et al. EPSL 222 (2004) 301-314) where those disturbances in geological sections of lacustrine sediments have provided a paleoseismic record spanning 50 000 years. The seismic history obtained in this way covers a much longer time interval than with any other technique.
