太阳活动与2001年昆仑山口西8.1级大震的相关性讨论

DISCUSSION ON RELATIONSHIP BETWEEN SOLAR ACTIVITY AND WEST TO KUNLUN MOUNTAIN PASS MS 8.1 EARTHQUAKE IN 2001

摘要:

2001年昆仑山口西8.1级大震发生在太阳活动第23周的峰年,太阳大磁暴在近东西向断层面上会引起涡电流加热作用,进而触发地震.经统计,中国和蒙古国境内8级大震中,发震断层为东西或近东西向者多在太阳活动峰年段发震;发震断层为南北或近南北向者则多在太阳活动谷年或附近发震.7.5级以上地震也有类似结论.

Abstract:

The great west to Kunlun Mountain Pass M_S 8.1 earthquake in 2001 occurred in peak term year of solar activity. The magnetic storms can induce eddy current heating on the fault plane of EW or near EW strike seismogenic faults, and trigger off earthquakes in the peak term years of solar activity. Based on statistics, among the M_S ≥ 8.0 great earthquakes in China and Mongolia, most events which occured on the fault with strike of EW or near EW are in the peak term of solar activity; but for others which occurred on the fault with strike of NS or near NS are predoninately in the valley term of solar activity. The similar result is also obtained for M_S ≥ 7.5 earthquakes.
