چکیده
ABSTRACT
Tehran, the densely populated capital of Iran has experienced several historical events. Its active deformation is documented by geological and geodetic studies. However, it is yet unclear how the active deformation is accommodated along various faulting trends. The seismic event of 20/12/2017 in Malard (suburb in western Tehran) was felt strongly in Tehran city, raised the question of N-S trending fault as active faults accommodating the deformation. Based on three outcrops affecting the Late Pleistocene deposits in northern Tehran are kinematic study conducted. The faulting mechanism of N-S trending faults accommodate in two was the deformation: 1- as compressive right-lateral strike-slip and 2- compressive with minor horizontal component.
