Optimal Methods and Parameters of Electromagnetic Monitoring in Seismically Active Areas

摘要: The article describes the methods of observation and data interpretation electromagnetic with a controlled source for seismically active regions Siberia. approach proposed by laboratory Fields IPGG SB RAS is being developed to estimate variations geoelectric parameters determining them solving an inverse problem. An analysis results VES monitoring using integral electrical conductivity parameter presented site in Selenginskaya depression Baikal rift zone. For territory Gorny Altai, measurement technique demonstrated several modifications TEM method resistivity anisotropy coefficient aftershock period 2003 Chuya earthquake. Attracting expands informativeness study, as it allows associated changes seismic regime assess degree activity fault zones.
