Magnetotelluric sounding of Kamchatka

Magnetotelluric sounding of Kamchatka

The magnetotelluric sounding data acquired in Kamchatka during the last 30 years have been analyzed and summarized. The interpretation is based on curves oriented along and across Kamchatka. Longitudinal and transverse curves can be affected by local geoelectric inhomogeneities. They were suppressed by conformal averaging. A bimodal interpretation of average longitudinal and transverse curves yielded a deep geoelectric model which can be adopted as a starting one to be subject to subsequent refining by 3D numerical modeling. The model involves a crustal conductive layer extending along central Kamchatka. In the east of the peninsula this layer is connected with transverse crustal conductive zones as wide as 50 km. Those zones have extensions toward the Pacific Ocean. Major centers of present-day volcanism are confined to the transverse zones. The upper mantle contains an asthenospheric conductive layer forming an uplift beneath the contemporary volcanic belt of Kamchatka.
