Earthquake of magnitude 7 hits Aegean Sea; jolts Turkey, Greece | Mausam Station

We spoke to well-known geologist Prof C S Dubey to know what lead to this earthquake and what is plate tectonics M 7.0 earthquake offshore Samos Island, Greece, occurred as the result of normal faulting at a shallow crustal depth within the Eurasia tectonic plate in the eastern Aegean Sea. The focal mechanism solution indicates that the earthquake occurred on a moderately dipping normal fault striking either eastward or westward. This mechanism indicates north-south oriented extension that is common in the Aegean Sea. Tectonics in the region surrounding this earthquake are relatively complex; to the south, Africa (Nubia) lithosphere subducts northward beneath the Eurasia plate at the Hellenic Trench; to the east, the Anatolian microplate (part of Eurasia) moves in a general westward direction, driving right-lateral faulting along its northern boundary, the North Anatolian Fault, and left-lateral faulting in southeast Turkey. The Aegean Sea region, western Turkey, and southern Greece where the October 30 earthquake occurred overall experiences north-south extension that is driven by southward migration of the Hellenic Trench. #TurkeyEarthquake #GreeceEarthquake #EarthquakeMagnitude7
