Contemporary crustal movements (CCMs) in Kamchatka

摘要

The works on geodetic monitoring of the contemporary crustal motions (CCMs) in the region of the Kamchatka Peninsula and Komandor Islands for the 40-year history of instrumental observations are reviewed. The examples of CCM recording by the classical geodetic methods and, since 1996, by the Global Positioning System (GPS) are presented. The deployment of the regional network for GNSS observations by the Kamchatka Branch of the Geophysical Survey of the Russian Academy of Sciences (KAMNET) made it possible to study the geodynamical processes at the junction of three major plates (Eurasian, North American, and Pacific) and smaller plates (Okhotsk and Bering). The interpretation of the examples of recorded CCMs is presented. The prospects of further development in the field of studying the geodynamics of the Koryak-Kamchatka region are outlined.
