1.前言地震是地壳破裂的现象。目前,尽管有关地震发生后的弹性波(地震波)的研究已有很大进展,而把地震作为破裂现象的研究却基本上没有什么进展。之所以如此,是由于破裂现象只能作为非线性现象对待,而这样做又非常困难。不过,茂木将岩石破裂实验时发生微破裂的微震活动性与天然地震活动性联系起来的研究可作为把地震视作破裂现象、力图阐明破裂动力学的开创性研究。茂木认为,地震和岩石破裂模式的不同特点取决于物质(地壳、岩石样品)不均匀性的程度。茂木的研究富有
1. Introduction Earthquakes are a phenomenon of crustal rupture. At present, although great progress has been made in the study of elastic waves (seismic waves) after the earthquake, little progress has been made in the study of the earthquake as a rupture phenomenon. This is so because the rupture can only be treated as a non-linear phenomenon, which is very difficult to do. However, Moki’s study of the association between microseismic microseismic activity and natural seismic activity during rock burst tests can serve as a groundbreaking study that seeks to disrupt the earthquake as an attempt to elucidate fracture dynamics. Maugham believes that the different characteristics of earthquakes and rock-burst patterns depend on the degree of inhomogeneity of matter (crust, rock samples). Motegi rich in research
