Geodynamic GNSS observations on the Kuril Islands

The network of geodynamic GNSS observations was deployed in 2006 throughout the Kuril island arc from Japan to Kamchatka. includes 11 stations continuous and periodic registration. article provides information on organization its current status. creation provided extensive material for studying modern processes segment subduction zone North American (Okhotsk) Pacific lithospheric plates. performed made it possible obtain first geodynamics region. presents an overview results previous years obtained by authors together with other researchers. source models largest seismic events are constructed basis instrumental data: Mw 8.3 2007 8.1 Simushir earthquake doublet 2013 deep-focus Okhotsk earthquake. At initial stage post-seismic process epicentral earthquakes, dependence asthenosphere viscosity observed displacement velocity Earth’s surface found. earlier were supplemented new data changes setting zone. dynamics transient decaying central part is studied. Stress relaxation crust at various stages this could be trigger powerful volcanic eruptions occurred 2009–2019 Islands. potential segments has been clarified modeling mechanical coupling It contributes a more accurate assessment hazard region methods. continuation Islands future will allow us study detail features
