摘要
1983年11月16日夏威夷Kaoiki 6.6级强震是一次近乎直立断层面上的走滑型破裂事件。然而,在主震发生前后,小震(M_L≥3.0)的震源机制解却表现出两种类型:(1)高倾角断面上的走滑型破裂;(2)地壳内低倾角间断面上的滑动,它们随时间交替和系统地变化。
The Kaoiki, Hawaii earthquake with magnitude 6.6 of November 16, 1983 was a strike-slip faulting event on a fault with large dip angle. The mechanisms of smaller events before and after the Kaoiki mainshock show that there were two kinds of mechanisms: (1) strick-slip on the fault with large dip angle; (2) slip on the crustal discontinuity plane with small flip angle. Systematic and alternative change of the mechanisms was observed.
