Abstract The Klyuchevskoy group of volcanoes (KGV) in Kamchatka includes three presently active (Klyuchevskoy, Bezymianny, and Tolbachik) located close together an area approximately 50 × 80 km. These have completely different compositions eruption styles from each other. We analyzed new data recorded by a temporary seismic network consisting 22 stations operated within the Tolbachik 2014–2015 conjunction with permanent PIRE deployed at Bezymianny volcano 2009. arrival times P S waves were...
Abstract Klyuchevskoy and surrounding volcanoes in central Kamchatka form the Northern Group of Volcanoes (NGV), which is an area particularly diverse intensive Pleistocene‐Holocene volcanism. In this study, we present a new seismic tomographic model crust uppermost mantle beneath NGV based on local earthquake data recorded by several permanent temporary networks including large‐scale experiment that was conducted 2015–2016 international scientific consortium. Having unprecedented resolution...
Abstract The Klyuchevskoy Volcanic Group is a cluster of the world's most active subduction volcanoes, situated on Kamchatka Peninsula, Russia. volcanoes lie in an unusual off‐arc position within Central Depression (CKD), large sedimentary basin whose origin not fully understood. Many gaps also remain knowledge crustal magmatic plumbing system these volcanoes. We conducted ambient noise surface wave tomography, to image 3‐D shear velocity structure and CKD surrounding region. Vertical...
Abstract Strong explosive eruptions of volcanoes throw out mixtures gases and ash from high-pressure underground reservoirs. Investigating these subsurface reservoirs may help to forecast characterize an eruption. In this study, we compare seismic tomography results with remote sensing petrology data identify deep subaerial manifestations pre-eruptive processes at Bezymianny volcano in Kamchatka shortly before its violent explosion on December 20, 2017. Based camera networks precursory...
The occurrence and the style of volcanic eruptions are largely controlled by ways in which magma is stored transported from mantle to surface through crust. Nevertheless, our understanding deep roots volcano-magmatic systems remains very limited. Here, we use sources seismovolcanic tremor delineate active part magmatic system beneath Klyuchevskoy Volcanic Group Kamchatka, Russia. distributed a wide spatial region over whole range crustal depths connecting different volcanoes group. activity...
Gorely is an active volcano located 75 km from Petropavlovsk-Kamchatsky, Kamchatka. In 2010–2015, it exhibited strong activity expressed by anomalously high gas emission. 2013–2014, we deployed a temporary network consisting of 20 seismic stations that operated for one year. We selected 333 events with 1613 P-wave and 2421 S-wave arrival times to build the first tomographic model this volcano. The was carefully verified using series synthetic tests. Our provides mechanism volatile feeding...
An international seismological collaboration in Kamchatka, Russia, investigates the driving forces of one world’s largest, most active volcano clusters.
The paper provides information on the objectives, methods, targets and some preliminary results of expeditionary work carried out within framework RSF project No.21-17-00049 by employees Institute Volcanology Seismology FEB RAS, Marine Geology Geophysics Pacific Geographical RAS Trofimuk Petroleum-Gas SB in 2022 2023. main objectives expedition were geological-volcanological, hydrogeological, geophysical, tephrochronological, paleoseismological studies. In accordance with set field teams...
Gorely is one of the most active volcanoes in Kamchatka with a rich magmatic and eruptive history reflected its composite structure. In 2013–2014, temporary network 20 seismic stations was installed on for year. During four months high degassing rate, activity mostly expressed form long-period (LP) tremor. this study, we have developed workflow based combination back-projection (BP), cluster analysis, matched-filter (MF) methods. By applying it to continuous records study period, were able...

<p>The strongest earthquakes and the largest explosive eruptions are confined to plate convergent boundaries. Many geodynamics aspects attract scientific community's attention since answers most important questions cannot be obtained without reliable information about deep structure. Geophysical studies of crust mantle provide essential for lithospheric blocks interactions, convection fluid migration. This data is necessary identify criteria assessing volcanic seismic...
