To detect seismic disturbances in the lower ionosphere,we have used the signals of very-lowfrequency radio transmitters and naturalradio signals—electromagnetic emission of lightning discharges—atmospherics. Onearlier results of observation of atmospherics, it was obtained that theearthquake effects are displayed as weight-hourly amplitude increases on theday of event or within 3 days after them. Possible earthquake precursors arealso manifested as one-day within one to several hours increases in theamplitude of atmospherics on average 5 - 12 days before the event. Analysisshows that seismic effects in the amplitude of atmospherics have been observedin the case of sufficiently strong magnitude M > 4.5 and not very deepusually no deeper than 50 km earthquakes. The effects of the events of theearthquake with magnitude of 8.2 occurring in the Sea of Okhotsk on 24.05.13not far from the Kamchatka Peninsula at a depth of 609 km considered in thiswork have shown that even deep earthquakes may have precursors in the form ofdisturbances in the lower ionosphere.
