The last point is that part of the epicenter is located in the Weihe Basin, This area is a sedimentary basin formed by the scour of Yellow River and Wei River, and the seismic sensation of seismic wave is amplified when passing through.
The earthquake caused multiple landslides in southern Shaanxi Qinling and the Loess Plateau in northern Shaanxi. The earthquake also caused the Weihe River to divert. The aftershocks lasted for decades.
