SEISMOGRAVITATIONAL PROCESSES ACCOMPANYING THE EVOLUTION OF SEISMIC FOCAL STRUCTURES IN THE LITHOSPHERE
https://doi.org/10.5800/GT-2020-11-1-0462
Abstract
Observations reflecting the structure and conditions of the seismogravitational process in the lithosphere were analyzed using the data on the catastrophic tsunamigenic earthquake of Maule (Chile) [Sobisevich et al., 2019]. Seismogravitational processes were first identified by a group of Soviet scientists from the city of Leningrad (now St. Petersburg) under the leadership of Professor E.M. Linkov [Linkov et al., 1982, 1990]. The study of these processes continues at the North Caucasus Geophysical Observatory of IPE RAS, which was established in 2004. Experiments are carried out using unique quartz tiltmeters designed by D.G. Gridnev, which ensure the stable registration of long–period seismogravitational processes on the scale of the Earth [Sobisevich, 2013; Sobisevich et al., 2017].
Keywords
