地震余震向量线初探

提出了一种预测地震的新方法－地震余震向量线法。通过多年对众多震例的研究，发现一次主震后，其最后一次最大余震与主震的联线（余震线和向量线）与下一次相关地震之间存在一定的关联性。以余震线长、最后一次最大余震与主震发生的相隔时间、最后一次最大余震与主震的震级三个已知条件，即可预测另一特定地区相关地震发生的地点时间、震级三要素。

A PRELIMINARY STUDY OF AFTERSHOCK VECTOR

In this paper, a new method for earthquake prediction, called aftershock vector method, is discussed. Studies have shown that, after a main earthquake, there exists a relationship between the line of the mainshock vector and the last biggest aftershock and the next correlative earthquake occurred in a certain area. By using the known data, such as vector length, time interval between the mainshock and the last biggest aftershock, and the earthquake magnitudes of the mainshock and the biggest aftershock, the three elements-place, time, and magnitude-of the next earthquake possibly occurred in a certain area can be predicted.
