Intensity scales, like the Modified Mercalli Scale and the Rossi-Forel scale, measure the amount of shaking at a particular location.

地烈度，如修利地烈度西福瑞级，表示特定地区的地表动强度。

Spatially , seismomagnetic effect caused by piezomagnetism and induced magnetism.is mainly distributed in the limited areas near epicenters , the bigger of the magnitude , the wider of the range.

在空间上，压磁、感磁等机制引起的磁效应主要分布在中附近的有限区域内，级越大，展布范围也越大。
