Abstract

In 2013, simultaneous observations of acoustic and electromagnetic emissions ranging from 200 Hz to 11 kHz were carried out in Kamchatka; as a result, abnormal surges of the emissions were registered 1–2 days before seismic events with magnitudes M LH ≥ 5 at a hypocentral distance up to 200 km. The most likely cause of the occurrence of the abnormal emissions in inherently different fields was activation of deformation processes preceding the earthquakes.
