ABSTRACT:
A groundwater radon monitoring in the
southern and western part of Sakhalin Island was carried out in 2014 in order
to study the correlation between radon anomalies and the seismic activity of
the region. The objects of investigations were located within large tectonic
dislocations of the island—the southern part of the Central Sakhalin fault and
the central part of the West Sakhalin fault. The soil gas monitoring was
carried out using a Sirad probe (Quarta-Rad, Russia) and the continuous radon
monitoring in the groundwater was carried out using a Radon Seismic Station
(CPC-05, NTM-Zashita, Russia). The effect of geochemical parameters, namely,
temperature, pressure and conductivity on the radon emission has been
studied. The present work contains an analytical protocol which is based on the
analysis of radon emitted from the fault planes, a geo- chemical precursor when
predicting the tectonic activity.
