Electromagnetic monitoring in the Baikal Rift Zone, seismicity triggering, and earthquake precursors

Many extraterrestrial geophysical anomalies are interpreted as earthquake precursors. However, the origin of these anomalies has been debated, and their physical relationship with earthquakes remains unclear. Many anomalies are attributed to lunar-solar-terrestrial interactions or to atmospheric effects and have no apparent relation to earthquake nucleation. Correlation of extraterrestrial pulses with earthquake origin times may be due to their triggering effect on tectonic processes in the lithosphere. Detection of these anomalies requires continuous monitoring of geophysical fields both in the upper (atmosphere) and lower (lithosphere) half-spaces, primarily with controlled-source radiophysical methods. High-precision measurements of amplitudes and phases of radio signals are provided by new recording equipment presented in the paper.
