Statistics of occurrence of pre-seismic anomalies in geoacoustic emission and in atmospheric field

The paper presents the statistics of occurrence of anomalous disturbances in high-frequency geoacoustic emission of near surface sedimentary rocks and in atmosphric electric field by the ground surface before earthquakes. Long-term continuous series of geoacoustic emission measurements in 2003-2012 at “Mikizha” observation site and atmospheric electric field data obtained within summer-autumn period in 2006-2008 at “Mikizha” site and in 2009-2012 at “Karymshina” observation site were used for the analysis. Anomalous disturbances of the emission and of the field were compared with the earthquake catalogue of Kamchatka Branch of Geophysical Service RAS
