Geology

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.

Damage

Five people died[3] and 30 were injured. Several houses collapsed, an additional 85 damaged, water mains broke and windows shattered.[4][5] Among the dead was a farmer who was crushed by a collapsing roof.[6] 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.[4][3]
