The possibility of joint perturbation of geoacoustic, emanation and atmospheric electric fields by the Earth’s crust — atmosphere boundary before an earthquake is considered. In order to detect it, simultaneous registration of these fields was carried out in Kamchatka in August–October 2012. Synchronous anomalous disturbances were recorded 13 days before an earthquake with the magnitude Mw = 5.6 at the distance of 140 km from an epicenter. It may be considered to be a complex short-term precursor.
