Computer program for modeling anomalous variations in radon volumetric activity based on the mechanism of its injection into the groundwater flow

Petropavlovsk-Kamchatsky geodynamic testing area has a network of subsoil gas monitoring stations. During the operation of the network, anomalies were registered in the field of subsoil gases, which precede strong earthquakes with a magnitude of M> 5. According to morphological features, they are divided into two types A and B. The paper describes the developed software for modeling the occurrence of radon anomalies based on a mathematical model of isotope injection under the influence of voltage pulses into a groundwater flow with complete transverse mixing.
