The 1983 Biga earthquake hit northwestern Turkey on 5 July 1983. It measured 6.1 on the surface-wave magnitude scale and was felt as far away as eastern Greece. The United States Geological Survey listed the earthquake among the "Significant Earthquakes of the World" for 1983.[2]
The Biga Peninsula is an area marked by active faults including strike-slip movement and en echelon divergent basins.
The earthquake was preceded by a foreshock nearly a year prior, and was followed by aftershock clusters.
Five people died[2] and 30 were injured. Several houses collapsed, an additional 85 damaged, water mains broke and windows shattered.[3] [4] Among the dead was a farmer who was crushed by a collapsing roof.[5] It also caused panic as far away as Istanbul and in eastern Greece. In Istanbul, there was some damage and people fled onto the streets.[3] [2]
