1822 Aleppo earthquake

The northern part of the Ottoman Empire (now northern Syria and the Hatay Province of Turkey) was struck by a major earthquake on 13 August 1822. It had an estimated magnitude of 7.0 M_s and a maximum felt intensity of IX (Destructive) on the European macroseismic scale (EMS). It may have triggered a tsunami, affecting nearby coasts. Damaging aftershocks continued for more than two years, with the most destructive being on 5 September 1822. The earthquake was felt over a large area including Rhodes, Cyprus and Gaza. The total death toll reported for this whole earthquake sequence ranges between 30,000 and 60,000, although 20,000 is regarded as a more likely number.
