随着地震预报计划的进展,日本的地震前兆现象观测实例的数量显著增加,力武(1986)已逐渐弄清这些前兆现象的特征。本文试图利用已查明其特征的前兆现象,研究预报未来地震发生的具体地点、震级(以下为 M)和发生时间。这里概不涉及前兆现象的发生机制,全部作为现象来说明。这次首先是为了同时定出地震的发生地点与震级,以后再研究发生时间。为达到这个目的,在下章中,对各种前兆调查了出现距离 D(前兆出现地点到震中的距离,以公里为单位
With the progress of the earthquake prediction program, the number of observational examples of earthquake precursors in Japan increased significantly. Liwu (1986) has gradually identified the characteristics of these precursory phenomena. This paper attempts to use the precursory phenomenon that has identified its characteristics to study and forecast the specific location, magnitude (M) and time of occurrence of future earthquakes. Here does not involve the occurrence of precursor phenomena, all as a phenomenon to illustrate. This time, first of all, to determine the place and magnitude of the earthquake at the same time and to study the time of its occurrence later. For this purpose, in the next chapter, various precursors were investigated for the presence of a distance D (the distance from the location of the precursor to the epicenter in kilometers
