The ground reptured for about 105 km along the Che-Lung-Pu fault. The horizontal peak ground accelerations measured at national strong ground motion stations TCU-065, TCU-072, TCU-078, and TCU-079, which can also measure structure responses and attenuation of ground motion, were 774, 465, 440, and 580 gal (1 gal = 1 cm/[s.sup.2]), respectively. In this accident, 49 542 dwellings were ...
