On November 8, the Church honors the memory of the great and terrible earthquake (earthquake) that happened in Constantinople (740) In 740, Constantinople and many cities in the Byzantine Empire were hit by a terrible earthquake. In the capital, some of the towers of the Theodosian wall collapsed, and many buildings were destroyed. This marked the end of the reign of the persecutor of Orthodox temples, the iconoclastic emperor Leo III the Isauri, who died a few months after this event. In memory of the deliverance from this disaster, a troparion and a contagion were drawn up, and a prayerful remembrance was established throughout the church.
