作为东海地震的前兆会出现多大程度的应变变化呢?对此,日本的岛崎和小木田使用假设的断层模式进行了计算。前兆现象的发生源可能在断层或断层的延长线上,这种想法是切合实际的。但现实中发生的地震是否按设想的机制发生,则令人有点担心。此外,断层模式的参数虽不能说少,但针对东海地震求出的计算结果在直感上也很难原封不动地与其他地区的地震结合起来。为了概括说明各种前兆现象,力武采用了茂木提出的球状震源模式。有 To what degree of change would occur as a precursor to the Tokai earthquake? In this regard, Shimazaki and Koshida of Japan calculated using a hypothetical fault model. The idea is that precursors can occur on the extension of faults or faults. However, it is a bit of concern whether the earthquake that occurred in the real world took place according to the mechanism envisaged. In addition, although the parameters of the fault model can not be said to be small, the calculation results obtained for the East China Sea earthquake are not intuitively straightforward to combine with earthquakes in other areas as they are. In order to summarize the various precursor phenomena, Liwu used the spherical source mode proposed by Motegi. Have
