2010年玉树7.1级地震序列时空演化特征及早期趋势判断

Abstract

Abstract: Temporal and spatial evolution characteristics of the 2010 Yushu M7.1 earthquake sequence have been analyzed and researched with data obtained by the Qinghai Earthquake Observation Network. The result suggests that selection of M_c=M_L1.1 can better characterize the spatial and temporal characteristics of Yushu earthquake sequence. Yushu earthquake sequence shows 3 intensification and decay phases in time, and in space has a sectional concentration distribution characteristics, and mainly in the northwest of, near and the southeast of mainshock epicenter. The question of early tendency judgement of the Yushu M7.1 earthquake also has been discussed by analogy method, b value and H value.

Key words: Earthquake sequence, Temporal and spatial evolution characteristics, The 2010 Yushu 7.1 earthquake, Early tendency judgement
