Istanbul (TK)

Istanbul and its surroundings are the settlements, which were damaged by many earthquakes along the history. Historic records of 120 earthquakes in destructive scales occured during the past 2000 years (Ambrayses, 2002) reveal a statistical recurrence of one destructive earthquake hitting Istanbul each century. Considering the local features of the ground of Istanbul where the buildings are situated, construction quality of the buildings, deterioration and corrosion problems related to the age of the buildings, the earthquake risk is increasingly growing.
