Among many other buildings, the temple of Tiberius, together with the Theatre and the Agora, were ruined. Fires broke out and many people perished. The ground opened up, causing additional damage, and landslides and slumping of the ground blocked the inner harbour. Neighbouring cities, including Ephesus 55 km to the south of Smyrna, suffered little or no damage. (reference #9116)
