The
115 Antioch earthquake occurred on 13 December 115 AD. It had an estimated magnitude of 7.5 on the
surface wave magnitude scale and an estimated maximum intensity of XI (
Extreme) on the
Mercalli intensity scale.
Antioch and surrounding areas were devastated with a great loss of life and property. It triggered a local tsunami that badly damaged the harbour at
Caesarea Maritima. The
Roman Emperor Trajan was caught in the earthquake, as was his successor
Hadrian. They escaped with only slight injuries and later began a program to rebuild the city.
