EVALUATION OF THE SIZES OF CRUSTAL MAGMA CHAMBERS BENEATH VOLCANOES AND OF THEIR TIME BEHAVIOR BASED ON THE VOLUME AND COMPOSITION OF ERUPTED MATERIALS AND CHAMBER DEPTH

Fedotov S.A.; Utkin I.S.; Utkina L.I. (2000)

Mathematical modeling was used to study the growth of crustal magma chambers beneath volcanoes due to the melting of the surrounding rocks and the discharge of the molten material during volcanic eruptions. The sizes of ...
FORMATION OF DIKES AND SILLS UNDER KLYUCHEVSKOI VOLCANO BY MAGMA INTRUSION THROUGH THE CONDUIT

Efimov A.B.; Ershova T.Ya.; Fedotov S.A. (1996)

The problem of magma intrusion through conduit walls is examined using the example of Klyuchevskoi Volcano. Magma intrusion takes place at all depths; the initial break through the wallrocks occurs mainly as a vertical ...
GROUND SURFACE DEFORMATION CAUSED BY SEISMIC AND VOLCANIC ACTIVITY IN THE KARYMSKY VOLCANIC CENTER DURING JANUARY 1996

Maguskin M.A.; Fedotov S.A.; Levin V.E.; Bakhtiarov V.F. (1998)

Quantitative characteristics are provided for horizontal and vertical ground-surface deformation on Karymsky and Akademii Nauk volcanoes measured after a large (M = 7.0) earthquake and a swarm of smaller events in the ...
MAGMA FLOW IN A CYLINDRICAL CONDUIT: A MATHEMATICAL MODEL

Mikhailova-Filippova M.I.; Fedotov S.A. (1997)

A mathematical model and a method of calculation are proposed for variable viscosity magma flow in a cylindrical conduit. An example of calculation is given for the conduit radius of 10 m, magma reservoir depth of 30 km, ...
ON THE EVOLUTION AND DIMENSIONS OF MAGMA CHAMBERS BENEATH VOLCANOES

Utkin I.S.; Fedotov S.A.; Utkina L.I. (1999)

This is a study of the evolution of crustal magma chambers beneath volcanoes driven by the melting of host rocks and the discharge of molten material by eruptions. A qualitative and quantitative description is given for ...
STUDY AND MECHANISM OF THE SIMULTANEOUS 1996 KARYMSKY VOLCANO AND AKADEMII NAUK CALDERA ERUPTIONS IN KAMCHATKA

Fedotov S.A. (1998)

This paper describes eruptions that commenced simultaneously in the Kamchatskiy volcanic center in 1996. A significant swarm of earthquakes with magnitudes as high as 6.9 occurred there on January 1, 1996, and was followed ...
THE FORECAST OF THE DECEMBER 5, 1997, MAGNITUDE 7.8-7.9 KRONOTSKY EARTHQUAKE, KAMCHATKA, AND ITS M ≥ 6 AFTERSHOCKS

Fedotov S.A.; Chernyshev S.D.; Matvienko Yu.D.; Zharinov N.A. (1999)

Four different prediction techniques were used at the Institute of Volcanology, Far East Division, Russian Academy of Sciences, to make successful long-term and intermediate-term forecasts of the December 5, 1997, magnitude ...
THE STUDY OF DEFORMATIONS OF THE EARTH'S SURFACE ON THE KAMCHATKA PENINSULA: REPEATED GEODETIC MEASUREMENTS

Fedotov S.A.; Maguskin M.A.; Sharoglazova G.A.; Zolotarskaya S.B.; Nikitenko Y.P. (1988)

The Kamchatka Peninsula, located at the joint of continental and oceanic plates, is a most interesting object for geodynamic studies. In view of this, during the last two decades eight geodynamic polygons have been organized ...
VOLCANIC ACTIVITY IN THE KARYMSKY CENTER IN 1996: SUMMIT ERUPTION AT KARYMSKY AND PHREATOMAGMATIC ERUPTION IN THE AKADEMII NAUK CALDERA

Muraviev Y.D.; Fedotov S.A.; Budnikov V.A.; Ozerov A.Y.; Maguskin M.A.; Dvigalo V.N.; Andreev V.I.; Ivanov V.V.; Kartasheva L.A.; Markov I.A. (1998)

This paper presents the results of investigating the 1996 eruptive activity of volcanoes in the long-lived Karymsky volcanic center of Kamchatka, where eruptions began simultaneously at Karymsky volcano and in the Akademii ...
