Regression analysis of reported earthquake precursors. I. Presentation of data

A probabilistic estimation of earthquake occurrence on the basis of the appearance times of multiple precursory phenomena.

“…Several kinds of compiled data about precursory phenomena are published at present (e.g., Niazi, 1985;E.C.S.S., 1985;Rikitake, 1986;Hamada, 1987). Recently we have also compiled (S.V.R.D., 1990) precursory phenomena in the world that had been reported in easily accessible documents.…”
