Retrospective evaluation of applicability of two-stage scheme for short-term forecasting of earthquakes (M ≥5) within the Southern Sakhalin region according to detailed catalog
A two-step method for detecting of the ﬁnal stage of preparation of strong earthquake (М ≥5) in the Southern Sakhalin region and prediction of its occurrence time was proposed. Retrospective evaluation of the possibility of using this approach is made using the detailed catalog data for the observation period from 2004 to 2008.
