Abstract
Seismic refraction and reflection profiles were acquired on two N-S directed crossing North Anatolian Fault (NAF) on the land area western of Sapanca Lake in October 2016. Buffalo gun source and Geometrics Geode acquisition system were used with asymmetrical split-spread seismic array. First arrivals were picked and travel time tomography inversion was applied for refraction data analysis. Shallow undulating layers were observed in the P-wave velocity sections suggesting the deeper faults of the NAF zone. Moreover, conventional seismic reflection data processing steps were applied to get stacked sections. Nearly vertical seismic discontinuities in a wide fractured zone were figured out from the sections by considering 1999 İzmit earthquake surface rupture. Deeper geometrical features of the faults illustrate a flowerlike structure. Thus, we interpret NAF from combination of undulated near surface layers by refraction and deeper subsurface geometry by reflection imaging.
