What the record says
NCEI’s account, from the sources it cites.
AD 1143 Nov 26, Prusa. An earthquake caused considerable damage and loss of life in Prusa (Bursa). The river that flows through the city stopped for three days. The shock was possibly felt in Constantinople. In Prusa (Bursa), an earthquake damaged buildings. It is not known whether there were any deaths. ln addition the river, which flowed through the city, dried up. The citizens were very alarmed, and it seems that public prayers were offered. Three days later an aftershock occurred and the stream began to flow again. This event is recorded by Michael the Syrian and placed in a.S. 1455 on Friday 26 latter Tesrin (26 November 1143), so the aftershock must have occurred on 29 November.
