Zhongwei-Tongxin fault

Six paleoearthquake events in the past 14,000 years have been recorded along the Zhongwei-Tongxin fault zone.

[4] The fault zone extends for about 240 km from just north of Jingtai in the west to near Tongxin in the east.

The eastern and southeastern segments are mainly thrust faults in type, accommodating shortening between the TJSB and the Ordos Block to the east.

[4] Slip rates along the Zhongwei-Tongxin fault have been estimated from the offset of landforms, the analysis of past earthquakes by trenching and GPS data.

[4] Paleoseismic investigations of the Zhongwei-Tongxin fault zone have revealed evidence of three major earthquakes.
