Seismic quiescence and activation

Abstract

It follows from the above-mentioned hypotheses that there exist various physical mechanisms of occurrence both of the seismic quiescence and of the foreshock activation. For the purpose of more fundamental understanding of such phenomena, the additional laboratory and fieldworks are required. In our opinion, special attention should be paid to the following directions. To investigate on the same catalogs of earthquakes both the quiescence and the activation in a complex, paying attention to their distribution in space, time, and magnitudes. To compare, where possible, the seismic patterns with the field of deformations being estimated based on the data of satellite geodesy. To compare, where possible, the seismic patterns with the data of deep geoelectrical and hydrogeological investigations with the purpose of better understanding of the role of water.
