摘要：Abstract1. The goal of this study is to determine of the tectonics and seismicity of the Biga region in the northwestern Turkey. Study is based on data collected from different institutions and field observations. Geological maps and 1/25,000 scaled topographical maps were used to determine the faultlines and their effect on landforms and drainage. Historical earthquakes show the activity of the region in terms of tectonics. Several earthquakes occurred larger than M≥ 5 in the historical period in the region. Tectonic activity accelerated during neotectonic period. Earthquakes occurring in the region show the activity of the area.
