Abstract

It has been discovered that, before the M 7.2 Zhupanovo earthquake of January 30, 2016 with a focal depth of 177 km, there was a negative five-day precursory anomaly of ten days in predicting time in the field of subsoil radon by observations in the network of the Petropavlovsk-Kamchatsky geodynamic test area. This anomaly with duration of 5 days and prediction time оf about 10 days is explained by the appearance of a so-called “geodeformation wave.”
