The 528 Antioch earthquake was the second major earthquake to affect the city in a span of two years. The shock occurring on 29 November, estimated at Ms 7.1, was viewed by its residents as the end of a series of disasters that had plagued Antioch. It killed at least 4,870 people and razed the remaining buildings that did not collapse in the earthquake of 526, and newly constructed ones.
The site of Antioch lies close to the complex triple junction between the northern end of the Dead Sea Transform, the mainly transform boundary between the African plate and the Arabian plate, the southwestern end of the East Anatolian Fault, the mainly transform boundary between the Anatolian Plate and the Arabian plate, and the northeastern end of the Cyprus Arc, the boundary between the Anatolian and African plates. The city lies on the Antakya Basin, part of the Amik Basin, filled by Pliocene to recent alluvial sediments. The area has been affected by many large earthquakes during the last 2,000 years.[2] The modern city of Antioch, now Antakya, was devastated by earthquakes in 1872 and 2023.[3][4]

The earthquake had an estimated surface-wave magnitude and local magnitude of 7.1 and 6.9, respectively. The maximum Modified Mercalli intensity was assigned in Antioch and Latakia, at X–XI (Extreme). Shaking was assigned IV (Light) in Lebanon.[3][5]
