The 1766 Istanbul earthquake was a strong earthquake with epicenter in the eastern part of the Sea of Marmara, in the Çınarcık Basin (or near the Princes' Islands, north of the basin)[2] which occurred in the early hours of Thursday morning, 22 May 1766.[1] The earthquake had an estimated magnitude of 7.1 on the surface wave magnitude scale,[2] and caused effects in a vast area extending from Izmit to Rodosto (now Tekirdağ).[3] In this area, the earthquake was followed by a tsunami which caused significant damage. The earthquake of 1766 was the last major earthquake to rock Constantinople (now known as Istanbul) because of a rupture of the North Anatolian Fault in the Marmara region.[4][5]
