The seismic intensity of the magistoseismic area is degree Ⅷ,with the orientation of long axis of isoseismic contour lines east-west. The Qingshuihezi fault is considered as the seismogenic fault of Hutubi M_S6.2展开更多

The earthquake effected areas mainly included 25 townships and towns,plus Hutubi County and Manas County in Changji,Hutubi and Manas. The total effected area is 12,450 km^2. In this paper,we summarize the seismo-tectonic background and geomorphic features of the earthquake zone. Under the guidance of the standard "The Earthquake Site Works-Parts4: Assessment of Direct Loss",the damage to buildings and lifeline systems with various structural types are introduced,and we ultimately estimate the direct economic losses to mud-wood houses and the destruction of brick-wood houses. Our results indicate that"The Urban and Rural Seismic Safe Housing Project"played a key role in reducing this earthquake disaster.展开更多

The earthquake relocation results show that the aftershocks are distributed in the east-west direction towards the north side of the southern margin of the Junggar Basin fault,and are mainly distributed in the western region of the mainshock. The distance between the mainshock after relocation and the southern margin of the Junggar Basin fault is obviously shortened. Combined with the focal mechanism and the spatial distribution of the mainshock and aftershocks,it is inferred that the southern margin of the Junggar Basin fault is the main seismogenic structure of the Hutubi earthquake.展开更多
