仅在十年前,从事地震带研究的地球物理学家,如果能把观测到的地面形变与某一断层面在深部的滑移量结合起来,就已心满意足了。但诸如触发地震断层活动的确实条件和地震活动在时空变化上的力学原因这类根本问题,仍然得不到解释。由于获得新近的观测资料和理论总结,这些以前彼此相互联系松散的问题,现在即将得以解决。人们对资料和力学理论形成一致看法的主要原因,是人们认识的转变,即认为地壳断层面的特定范围内或以脆性为主或以韧性为主,而且一个或若干断层在不同的范围内发生不断的相互作用。
Only ten years ago, geophysicists engaged in seismic zone studies were satisfied with the combination of the observed ground deformation and the deep slippage of a fault plane. However, fundamental issues such as the exact conditions triggering the seismic fault activity and the mechanical causes of the temporal and spatial variations in seismicity remain unexplained. As a result of recent observations and theoretical summaries, these problems that were previously inextricably linked to each other are now about to be resolved. The main reason for the formation of a consistent view of data and mechanistic theory is the recognition of a shift in the belief that a particular crustal fault plane is dominated by either brittle or ductile faults and one or more faults occur in different ranges Constant interaction.
