Based on the integration and analysis of the published theoretical results and field observations, the possibility is considered of a joint perturbation in geoacoustic emission, radon, thoron, and the atmospheric electric field before an earthquake. A scheme is proposed for the formation of this perturbation in the presence of near-surface sedimentary rocks at the observation point and their extension. In order to detect such a perturbation, simultaneous measurements of geoacoustic emission, radon, thoron, and the atmospheric electric field were carried out for the first time in Kamchatka in summer and autumn 2012–2013, and the joint anomalous perturbation in these parameters was recorded.
