决定地震发生时的断层破裂能量和了解一个断层带的孕育与发展都需要地震和地质数据的结合.在一个大地震的发生过程中,藉由地震仪的记录分析,了解地震断层破裂过程中其断层的几何破裂行为及其机制,甚至分析其运动学上的灾害行为.在地震源分析中文章作者将以上行为分析称为地震的巨观分析.而地震的微观分析,则是以探讨当地震断层及破裂前缘持续向前前进时,其所需的破碎能量及其形成的极小颗粒之断层泥的物理化学机制.此断层滑移带中的断层泥之物理机制、化学组成及地震断层滑移带厚度,皆为了解地震滑移时摩擦行为及能量释放的重要参数.地震的巨观及微观行为的结合分析,为地震学上重要的突破,使人们得以进一步了解地震破裂过程中的摩擦行为、温度及压力的变化,并探讨地震时造成的地表位移、速度及加速度行为.但断层滑移带的断层泥并不易获得,除非有清楚的深部断层几何,并能以深钻的方式取得断层泥材料进行分析.1999年7.6级的台湾集集大地震产生地表或近地表8—12m的滑移,此近地表的滑移是钻井容易达成的,因此提供一次难得的机会,得出大地震滑移带的断层泥了解大滑移断层的动力机制.而2008年四川汶川地震为另一了解此巨观与微观机制的地震.
Determining the energy of fault rupture at the time of an earthquake and understanding the gestation and development of a fault zone require the combination of seismic and geological data.During the occurrence of a major earthquake, The geometric rupture behavior of the fault and its mechanism, and even the analysis of its kinematic disasters.In the seismic source analysis, the author of the article referred to the above behavioral analysis as the giant earthquake analysis, while the microscopic analysis of the earthquake is based on the study of the earthquake The physical and chemical mechanisms of fault energy and the formation of tiny particles of fault mud when the fault and the front of the fault continue to move forward The physical mechanism, chemical composition and seismic fault of fault mud in this fault slip zone The slip band thickness are all important parameters to understand the frictional behavior and energy release when the earthquakes slip.The combination and analysis of the megacity and micro-behavior of the earthquakes is an important breakthrough in seismology so that people can get a better understanding of the Frictional behavior, temperature and pressure changes, and to investigate the surface displacement, velocity and acceleration behavior caused by the earthquake.But the fault slip zone fault And are not readily available unless there is clear deep fault geometry and can be obtained by deep drilling of fault-gouge material for analysis. The magnitude 7.6 slip of Taiwan’s Jiji earthquake in 1999 produced a surface or near-surface slip of 8-12 m, Of the slip is easy to reach by drilling, thus providing a rare opportunity to come to a conclusion about the dynamic mechanism of the fault slip in the slip zone of the Great Earthquake while the 2008 Wenchuan Earthquake in Sichuan is another source for understanding this macro and micro Mechanism of the earthquake.
