Tan-Lu fault

The southern segment of the Tan-Lu Faults (south of Tancheng) was formed at the end of the Triassic period as a strike-slip fault east of the Qinling-Dabie collision zone between the Yangtze plate and the Sino-Korean plate. During the Yanshan period of the Mesozoic Era, due to the westward subduction of the Pacific plate under the Eurasian plate (in a broad sense), the Tanlu fault belt extended to the north and was transformed into a thrust fault. Afterwards, although the Tan-Lu Faults was once restored to a strike-slip fault, it was still dominated by thrust movement for most of the time.^[2]

During the neotectonic period, the Tan-Lu Faults was a left strike-slip-thrust fault. There have been many major earthquakes along this fault zone in history, such as the Tancheng earthquake in 1668 and the Haicheng earthquake in 1975.
