Abstract:

Based on the analysis of the geological structure background, and the collected earthquake (ML≥2.8) data in Hetao seismic zone since 2000,the focal mechanism of 256 is calculated by using P wave first motion amplitude ratio method(APAS) and CAP retrieval method. Taken the fault plane slide angle as the indicater, we made the space and time distribution chart of the focal mechanism types in different zones, which depicts the space and time variation of the stress field in Hetao seismic zone. The results show that the fault plane slide angle in Linhe basin appeared dominant in horizontal ±20°, a significant feature of strike slip type. This type of earthquakes are distributed mainly in Langshan Seertengshan fault zone, Linhe fault and Wulashan fault zone. The normal-strike-slip type of earthquakes are distributed mainly between Bayanwulashan fault zone and Benjin fault. Hubao basin faults are mainly strike-slip type, but the slide rangles are dispersed with on clear direction and space correlation West side of Hubao basinand Baotou-Xishanzui rise show a small-scale slip focal stress field characteristics; thrust and normal earthquakes take a great proportion in the inside and east side of Hubao basin resulted from the vertical differential movement,and the focal mechanism is structure-dependent. According to the analysis in the study area and in the period,the gravitational field in the seismic belt varies non-uniformly in space and time. The non-uniformty is mainly result by the limitation of the time span and the magnitude

Key words: Hetao seismic belt, focal mechanism type, moment tensor inversion, amplitude ratio, rake
