| 摘 要： | 印尼8.7级地震发生后,在不到2个月时间内,在中国大陆相继发生了3次后续中强地震(2004年12月26日云南双柏MS5.1地震、2005年1月26日云南思茅MS5.1地震、2005年2月15日新疆乌什MS6.2地震),印尼地震和这3次后续地震是否存在触发关系?计算了印尼地震在3次后续地震破裂面上的动库仑应力变化和静库仑应力变化。静应力变化量小,低于一般认为的触发阈值(0.01 MPa);动应力变化峰值为10-1MPa,可能是这3次后续地震的触发因素。 |
| 关 键 词： | 动应力触发 库仑破裂应力 印尼MS8.7地震 |

| Abstract: | In two months after Indonesia M_S8.7 earthquake,three moderately strong earthquakes(December 26,2004 M_S5.1 Shuangbai earthquake,January 26,2005 M_S5.1 Simao earthquake and February 15,2005 M_S6.2 Wushi earthquake) occurred in China' mainland.Is there triggering relation between Indonesia M_S8.7 Earthquake and the three subsequent earthquakes? In this article we calculate the static and dynamic Coulomb stress changes in failure planes of the three subsequent earthquakes for Indonesia M_S8.7 Earthquake.The value of static stress change is smaller than the threshold one of triggering value(0.01 MPa);The peak change of dynamic stress is about 10~(-1) MPa.So the change of dynamic stress is probably the triggering factor of the three subsequent earthquakes. |
