Özet

The Karadere segment of the North Anatolian Fault (NAF) is the easternmost part that ruptured during the 17 August 1999 Izmit earthquake (Mw 7.4). It has a different orientation, at N65 degrees E to other segments which have a nearly E-W trend, and lesser dextral displacement, with maximum 2.3 m in contrast with 5.2 m in the ruptured neighbouring western segment. Two palaeoseismological trenches, at Kazimiye and Karadere sites, were excavated on the central part of the Karadere segment to determine the timing of past earthquakes.
