Abstract

This paper presents the results of joint processing of satellite data providing record of ionospheric parameter anomalies, thermal anomalies and dynamics of lineament systems during the preparation and occurrence of a strong earthquake (M6.2, 24.08.2016, Italy). We describe the methodology for joint analysis of various geophysical parameters in monitoring of seismic areas. Based on the results of step-bystep processing of satellite data, it was demonstrated that 2 months before the seismic event, an increase in the number of regional lineament systems of the NW-SE direction began; one month before, the growth of secant lineaments began. An anomaly of outgoing long-wave radiation was recorded in the epicentral area of the earthquake; anomalies of land surface temperature were observed a week before the earthquake. Four days before the seismic event, a decrease in the ionospheric electron density was observed, and its increase was recorded the day before and immediately on the day of the earthquake. According to the obtained results, we conclude that anomalous variations of the studied geophysical fields are earthquake precursors.
