The February 12,2014,MS7.3,earthquake in Yutian,Xinjiang,China,occurred as a result of shallow strike-slip faulting in the tectonically complex region of the northern Tibetan Plateau,with a depth of 17 km.This earthquake occurred several hundred kilometers north of the convergent India-Eurasia plate boundary.The epicenter location of the Yutian earthquake,36.1° N,82.5° E,is 110 km north of Yutian County,Hotan Prefecture.A large number of aftershocks from ML2.0 to ML3.0 occurred until 12:00oclock,February 23,2014 and the largest aftershock,MS5.7,occurred at 17:24 p.m.,February 12,2014.The b and h value of Yutian sequence are 0.70 and 1.29,respectively.The waiting time method reveals that the strong aftershocks above ML4.5comply with a linear relationship,which is consistent with the characteristics of a mainshock-aftershock sequence.Furthermore,we calculate the source parameters and analyze the rupture process based on the empirical relationships for the Yutian earthquake,and the results indicate a frictional undershoot behavior in the dynamic source process of the Yutian earthquake,which is also in agreement with the lower and similar b values compared with the 2008 MS7.3 Yutian earthquake and the 2012 MS6.2 Yutian earthquake. The February 12,2014, MS7.3, earthquake in Yutian, Xinjiang, China, occurred as a result of shallow strike-slip faulting in the tectonically complex region of the northern Tibetan Plateau, with a depth of 17 km. hundred kilometers north of the convergent India-Eurasia plate boundary.The epicenter location of the Yutian earthquake, 36.1 ° N, 82.5 ° E, is 110 km north of Yutian County, Hotan Prefecture. A large number of aftershocks from ML2.0 to ML3 .0 occurred until 12: 00oclock, February 23,2014 and the largest aftershock, MS5.7, occurred at 17:24 pm, February 12,2014. The b and h value of Yutian sequence are 0.70 and 1.29, respectively. The waiting time method reveals that the strong aftershocks above ML4.5 comply with a linear relationship, which is consistent with the characteristics of a mainshock-aftershock sequence. Future, we calculate the source parameters and analyze the rupture process based on the empirical relationships for the Yutian earthquake, and the r esults indicate a frictional undershoot behavior in the dynamic source process of the Yutian earthquake, which is also in agreement with the lower and similar b values ​​compared with the 2008 MS7.3 Yutian earthquake and the 2012 MS6.2 Yutian earthquake.
