Experimental detection of the four-day variations of radon emanation caused by moon phases

Abstract

For the first time four diurnal variations of radon emanation from soil were found and measured. By results of measurements it is confirmed, well-known in the world literature, regularity – submission of volume activity of radon to barometric formula. Correlation of seismic peaks of magnitude of earthquakes with peaks of activity of radon is also found. In seismic hazard zones and, in particular, in mountain areas of Kazakhstan, the problem of short-term earthquake prediction and research of tectonic processes are highly relevant. However, according to the authors, the question of short-term earthquake prediction is still open. The conclusion about the possible dependence of the correlation of radon emanation not only earthquakes, but also from "moonquakes" that is, from the uplift of the soil due to gravitation of the moon - "lunar tides" is drawn.
