This work presents the project of the first stage of implementation of the integrated instrumental system of volcanic activity monitoring in Kamchatka and the Kuril Islands. The system of monitoring was designed for the purpose of ensuring public safety, aviation safety, and reducing economic losses caused by volcanic eruptions. The most active and dangerous volcanoes in Kamchatka (North and Avacha groups of volcanoes) and the Kuril Islands (volcanoes on the islands of Kunashir and Paramushir) are of first priority for monitoring. For this purpose, special observation points are planned to be installed on the volcanoes. The system of monitoring will include a complex of observations (broadband seismic station with a large dynamic range, tiltmeter, devices for gas, acoustic, and electromagnetic observations, and video camera). All the data will be passed to information processing centers in real time. New methods and algorithms of automatic and automated identification of the volcanic activity level and the probabilistic volcano hazard assessment have been developed.  相似文献   

Modeling of coseismic crustal movements initiated by the May 24, 2013, M w = 8.3 Okhotsk deep focus earthquake

The Okhotsk deep focus earthquake (M _w = 8.3), the largest in the history of instrumental seismology, occurred on May 24, 2013, at 05:45 UTC in the Sea of Okhotsk near the western coast of the Kamchatka Peninsula. For the first time we have succeeded in catching the field of horizontal and vertical coseismic offsets generated by a strong deep seismic event, and investigating its characteristics using continuous GPS measurements. Based on these data and taking into account the seismological information, we have developed a dislocation model of the Okhotsk deep focus earthquake.  相似文献   

Contemporary crustal movements (CCMs) in Kamchatka     

V. E. Levin  V. F. Bakhtiarov  N. N. Titkov  S. S. Serovetnikov  M. A. Magus’kin  A. V. Lander 《Izvestiya Physics of the Solid Earth》2014,50(6):732-751

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.  相似文献

Geodynamic studies of the April 20(21), 2006 Olyutorskii earthquake based on observations by the Kamchatka GPS network

This paper presents results from an analysis of GPS observations made by the Kamchatka regional GPS network (KAMNET) in relation to the Olyutorskii earthquake and plate interaction. The coseismic changes were interpreted for the Olyutorskii earthquake and its largest aftershock (May 22, 2006, M _W = 6.6) within the framework of a dislocation source in an elastic half-space.  相似文献
