Research Abstract

We have analyzed 35 wide-band magnetotelluric data at Armutlu peninsula, where we had aftershock activity of 1999 Izmit earthquake, and found the earthquakes distribute outside of the crustal conductors. We also obtained 14 ocean-bottom magnetotelluric data in the Marmara Sea in the period range of 100-10,000 seconds. After preliminary 2d, 3d modeling, inhomogeneous resistivity structures are being revealed in relation to asperities.
