| Abstract: | The 1985 Wuqia earthquake occurred in Kezilesu Valley about 40 km southeast ofWuqia. Intensity IX effects were experienced at the epicenter. The earthquake belongs tomainshock-aftershock type. Its aftershocks have the characteristics of wavy attenuation. Themajority of the houses in Wuqia county town and Wupaer town collapsed and were destroyed. The mainshock produced a surface rupture zone along the Kezilesu valley terraces inthe meizoseismal area. The rupture is about 15-km long, 100-to 800-km wide,which consistsof seismic faults, compression ridges and seismic cracks. It is Kazikeerte reversed fault tocause the 1985 Wuqia earthquake. Because the quake is a fold-type earthquake, it has thesame feature that the seismic disaster on the upper side of the fault is heavier than that onthe lower one as other fold-type earthquakes. |
