Three centuries of seismic activity have been recorded in the Corinth Rift, in central Greece. This study focuses on turbidites formed in a submarine canyon fed by two fan deltas that experience frequent slope failure. This study attempts to assess if seismic activity can be determined by correlation of these turbidites. 

Four sediment cores retrieved from the canyon were examined to describe the sedimentology and were categorized. This was done using visual analysis, CT Scan, and grain-size analysis. 

Correlation of the cores was done using magnetic susceptibility (MS), gamma density, color reflectance data, and XRF data, exclusively using background sedimentation. Using this correlation, simultaneous large events were then linked.
