ABSTRACT

In this study we attempt to estimate parameters that are related to path and near-surface effects, due to earthquakes that occurred in northwestern Turkey, by drawing on data from the Istanbul Earthquake Rapid Response System (IERRS) that is operated by the Department of Earthquake Engineering at Boğaziçi University’s Kandilli Observatory and Earthquake Research Institute. Our data set includes over 4677 strong motion recordings from 115 stations of the IERRS. The records are associated with events having local magnitudes ranging within 4.0
