Pronounced changes of upward natural gas migration as precursors of major seismic events

Pronounced changes in the rate of natural gas migration to the surface of the Earth in the vicinity of faults and fractured zones can be used as precursors of major seismic events. The authors propose to use them in conjunction with other integral parameters characterizing the energetic state of a tectonic system for the development of a multicomponent earthquake prediction technique. Thus, it is necessary to develop and implement a stationary natural gas mobility monitoring system covering the vicinity of major faults and fractured zones at the area of interest.
