Precursors of large Kamchatka earthquakes based on monitoring of seismic noise

Abstract

This paper presents results from a monitoring study in high frequency seismic noise in Kamchatka during 1992–2006 and reports their use for predicting large regional earthquakes (M ≥ 6.0) in an epicentral distance range Δ within 400 km. The prediction is based on an original method using earth tides as the standard external excitation to study patterns of seismic emission. The method as used at present is described in detail. Guidelines are delineated for future refinement of the prediction method.
