Abstract

On the basis of detailed bathymetric data collected in March 1999 and January 2000 at two sites nearby the Hersek Delta, Izmit Bay, possible bathymetric changes caused by 17 August 1999 Kocaeli Earthquake were studied. Data acquisition systems, techniques and parameters were held same in all surveys. Obtained differences were estimated taking into account possible error sources for single-beam echosounders and depth reductions, along with the methodology for producing depth error budgets. The results reveal some bathymetric changes and some systematic variations in the depth difference, especially on the southern block of the right-lateral strike slip master fault.
