Background and detail

Under the Venetians, the city of Candia (modern Heraklion) had been reputed the best fortified city of the Eastern Mediterranean. The earthquake occurred on the morning of October 12, 1856, at 02:45 am local time. It was an intermediate-depth event on a fault within the subducting African plate, with an estimated magnitude of 7.7 to 8.3.

Impact. The earthquake destroyed most of the over 3,600 homes in Heraklion. Damage and human losses were reported across the Ottoman Empire, including present-day Turkey, Cyprus, and the Middle East. The shockwaves were felt intensely over a wide area extending from Sicily to the Levant and North Africa, causing additional deaths and damage in these regions.
