Instrumental recording of slow deformation waves in the South Baikal geodynamic study site

Abstract

Instrumental monitoring of rock deformation in the South Baikal geodynamic study site showed that they are realized in the form of long-term variations in different directions superimposed with short-time anomalous spikes. Analysis of the measured spatiotemporal monitoring series showed that anomalous deformations are caused by the propagation of deformation waves through the mountainous rocks. We estimated their lengths, periods, directions, and velocity of spatial migration. We found that propagation of deformation waves is accompanied by an increase in the temperature of rocks at each point of monitoring.
