Abstract : The
North Anatolian Fault Zone (NAFZ) crosses almost the whole northern
part of Turkey. The active tectonism of NAFZ causes major earthquakes.
Some big earthquakes originated from the NAFZ caused loss of lifes
and properties. The movements of the fault create stress and strain
in the surrounding area. Varying tectonic stress on blocks generates
changes of the magnetization due to the magneto-elastic rock properties.
In this paper, the previously modeled amphibolite complex that poduce
the magnetic anomaly in Mudurnu valley, between Adapazari and Bolu,
around Taskesti has been remodeled by an automatic three-dimensional
modeling method. The new model suggests a magnetized body extending
from near surface to the depth of 1.2 km having a susceptibility
value of 22 x 10-2(SI). The parameters of the new 3-D
model improve the interpretation of tectonomagnetic signals.
