Abstract

This study aimed to investigate the effects of magnitude, focal depth and the thickness of the overburden material on the length of the surface rupture caused by an earthquake; and to propose new empirical equations between the surface rupture length and the earthquake source parameters. To accomplish this purpose, a series of tests were carried out in the laboratory utilizing a set up simulating a strike-slip faulting mechanism. In addition to laboratory tests, a database was established from the earthquakes that have occurred in Turkey and all over the world. Consequently, new empirical equations were suggested between magnitude and surface rupture length and focal depth of an earthquake based on the data obtained from the laboratory model tests and real earthquakes.
