Some features of acoustic and electric responses of near-surface sedimentary rocks during deformations by seismic waves from strong earthquakes (Mw > 6.5)
Acoustic and electric responses of near-surface sedimentary rocks are considered. They were recorded during the deformations by seismic waves from six earthquakes with magnitude Mw = 6.6-7.7 at the distances of 131-728 km from epicenters in Kamchatka region. Behavior of both responses during soil di...

| Summary: | Acoustic and electric responses of near-surface sedimentary rocks are considered. They were recorded during the deformations by seismic waves from six earthquakes with magnitude Mw = 6.6-7.7 at the distances of 131-728 km from epicenters in Kamchatka region. Behavior of both responses during soil displacement and displacement velocity during wave propagation are un-der the analysis. The dependence of intensity and character of the responses manifestation on earthquake magnitude and the distance to its source had been discovered by the authors earlier and is confirmed in the work. It was discov-ered that the occurrence of acoustic response in kilohertz range correlates well with the behavior of soil displacement velocity vector and its spectrum. |
