A powerful seismic event originating beneath the Aegean Sea at a depth of approximately 61 to 100 km generated catastrophic shockwaves. The earthquake's epicentral region near Crete and Rhodes sits along one of the most seismically active fault zones in the Mediterranean, where the African and Eurasian tectonic plates converge.
On October 12, 1856, an earthquake estimated at magnitude 7.7 to 8.3 struck the Aegean Sea region. The shaking was felt from Sicily across the entire Ottoman Empire to the Levant and North Africa. Crete suffered the worst destruction, with over 500 bodies recovered in Heraklion alone. Seaquakes were reported off the Egyptian and Italian coasts.
The earthquake caused severe structural damage across multiple regions. In Cairo, buildings collapsed and seiches formed in canals. In Malta, the historic 1638 Għajn Ħadid Tower lost its upper floor. Human casualties were recorded throughout Cyprus, present-day Turkey, and the Middle East, marking it as one of the most destructive Mediterranean earthquakes of the 19th century.
