The Marash earthquake occurred in the area of Marash during the early morning hours of November 29, 1114. It had an estimated surface-wave magnitude between 7.4 and 7.7 and an epicenter location in modern-day Turkey. The mainshock was preceded by two destructive foreshocks in August and November that same year. At least 40,000 people were killed in the earthquake; a number contested by historians due to the small population in the area at the time. These earthquakes were associated with seismic activity on the East Anatolian Fault.
