AD 181 May 3, Mudopolis. A relatively large earthquake in Bithynia caused serious damage in Nicomedea and the surrounding region as far as the region around Mudopolis and the River Sangarius. The imperial government provided funds for the restoration of Nicomedea. The event is mentioned only by Malalas, a sixth century writer who places it during the reign of Commodus (AD 180-192), at dawn on 3 May. The year of the event is not given but the events that followed can be dated to AD 181. The earthquake affected a large area, which extended to the region of Mudopolis, which should be understood as 'Midou poleos', the town or Midaeum. which is located south of the upper reaches of the River Sangarius, on the military road to Dorylaeun1, 130km south of Nicomedea, near modern Karahuyuk (Thurm).
