Karamürsel was heavily damaged during the devastating 1999 İzmit earthquake ( August 17 , 1999 ) which rocked the eastern part of Marmara Region . 164 people lost their lives in Karamürsel in the earthquake , and many were left homeless . After the earthquake many people left this town for other parts of Turkey , and the place had a resemblance of a ghost-town for the winter of 1999 . It is now returning to its old days , with the houses being repaired and the business being reopened . During the earthquake , a considerably damaging tsunami hit both the northern and southern sides of the İzmit bay in about one minute . Even the tsunami was not very large , subsidence and coastal landslides , have left a substantial portion of the towns of Gölcük , Degirmendere and Karamürsel inundated by the sea ( Altinok et al. , 1999 ) . The coast of Karamürsel is now repaired and reconstructed
