Systematization of Ionospheric, Geodynamic, and Thermal Precursors of Strong (M 6) Earthquakes Detected from Space

The article describes the formation features of short- and mid-term strong (M 6) earthquake precursors detected from space. A database has been created that contains parameter variations for the ionospheric, geodynamic, and thermal fields detected from space during the preparation and occurrence of significant seismic events. This database is an important element of a unified integrated system for monitoring catastrophic natural disasters. We present a technique for the collection and systematization of satellite and related information, as well as data processing methods to obtain information on irregular variations of various geophysical fields in seismic regions. This database contains general information on more than 4000 earthquakes, as well as the characteristics of 80 strong earthquakes (magnitudes from 6.0 to 9.1) that occurred in various world regions between 1990 and 2017. We also present examples from the database of visualization and analysis of data for various precursors of an earthquake that occurred in Italy on August 24, 2016 (M = 6.2).
