“…When incoming into the atmosphere, they increase the ground air ionization and conductivity that is accompanied by atmospheric electric field decrease by the surface in fair weather conditions [23]. Radon and thoron content in soil gas depends, in particular, on rocks deformation and increases there and in the near-ground air before earthquakes [3,[24][25][26][27].…”

The authors generalize and analyze the investigation results of joint anomalies of high-frequency geoacoustic emission and atmospheric electric field by the ground–atmosphere boundary which were detected by them in Kamchatka. These anomalies are observed as geoacoustic emission increases in kilohertz frequency range and bay-like decreases of atmospheric electric field with the sign change which occur close in time during calm weather conditions. It is the authors’ opinion that the common nature of these anomalies is short-time stretching of the near-surface sedimentary rocks at an observation site during unstable tectono-seismic process. A scheme of the detected anomalies formation has been suggested.
