ABSTRACT: In this research, Tabas
area, which is located in central Iran, was selected as the study area and
three geomorphic indices were calculated for its structural fronts. Through
averaging these three indices, we obtained index of active tectonics (IAT). The
values of the index were divided into classes to define the degree of active
tectonics. Therefore, relative tectonic activity was calculated and their
values were classified and analyzed in two groups. Regions were identified as
high and moderate levels. In analyzing data and combining them with tectonic
setting, the results were often associated and justified with regional geology.
Our results show that the highest value is located along Shoutori fault, which
shows 2 class of relative tectonic activity (high level). Also, moderate values
are located along Ereshk, Ezmeighan and Jamal faults (moderate level).
According to these results, Shoutori fault is the most active fault in the
study area and this situation is compatible with its position as a mountain
front fault.
