East Anatolian Fault East Anatolian Fault The East Anatolian Fault is a major strike-slip fault zone in eastern Turkey. It forms the transform type tectonic boundary between the Anatolian Plate and the northward-moving Arabian Plate. The difference in the relative motions of the two plates is manifest in the left lateral motion along the fault. The East and North Anatolian faults together accommodate the westward motion of the Anatolian Plate as it is squeezed out by the ongoing collision with the Eurasian Plate. The East Anatolian Fault runs in a northeasterly direction, starting from the Maras Triple Junction at the northern end of
Geology of the Antarctic Peninsula and was active on King George Island during most of the Tertiary. The younger system of faults, also a series of strike-slip faults, displaced the older system and formed transverse to the island arc. Movement of the fault activity was caused by the counterclockwise rotation of the Antarctic Continent with respect to the subduction zone. The last and most recent stage in the evolution of the Antarctic Peninsula subduction zone is the opening of the Bransfield Rift, creating the Bransfield back-arc basin from the Oligocene to the present day. This basin separates the inner, older magmatic arc (mainland Antarctic Peninsula)
