摘要

A lack of precise understanding of the complex earthquake processes has come in the way of earthquake prediction. It is well established that the hypocentral region of an earthquake undergoes structural and geological changes prior to its occurrence, leading to variation in physical properties of the rocks. In the present paper, the electrical resistivity measurements in and around Latur, Maharashtra, India from 1984 to the present time bring out an interesting correlation between earthquake occurrences and resistivity values. In intraplate stable continental regions like Latur where the possible location is broadly known, the temporal variations of electrical resistivity may zero down the period of occurrence of high magnitude earthquakes to a couple of months.
