Asymmetric caldera-related structures in the area of the Avacha group of volcanoes in Kamchatka as revealed by ambient noise tomography and deep seismic sounding

Koulakov Ivan; Jaxybulatov Kayrly; Shapiro Nikolay M.; Abkadyrov Ilyas; Deev Evgeny; Jakovlev Andrey; Kuznetsov Pavel; Gordeev Evgeny; Chebrov Viktor (2014)

Avacha group includes two active and potentially dangerous volcanoes, Avachinsky and Koryaksky, located close to Petropavlovsk-Kamchatsky, the main city of Kamchatka. We present the results of two independent seismic studies ...
ESTIMATION OF THE SULFUR DIOXIDE EMISSION BY KAMCHATKA VOLCANOES USING DIFFERENTIAL OPTICAL ABSORPTION SPECTROSCOPY

Melnikov D.V.; Ushakov S.V.; Galle B. (2014)

During the 2012-2013 we have measured SO2 on Kamchatka volcanoes (Gorely, Mutnovsky, Kizimen, Tolbachik, Karymsky, Avachinsky) using DOAS (differential optical absorption spectroscopy). Mobile-DOAS, on a base of USB2000+, ...
Geochemical characterization of marker tephra layers from major Holocene eruptions, Kamchatka Peninsula, Russia

Kyle Philip R.; Ponomareva Vera V.; Rourke Schluep Rachelle (2011)

Kamchatka Peninsula is one of the most active volcanic regions in the world. Many Holocene explosive eruptions have resulted in widespread dispersal of tephra-fall deposits. The largest layers have been mapped and dated ...
GREAT EXPLOSIVE ERUPTIONS ON KAMCHATKA DURING THE LAST 10,000 YEARS: SELF-SIMILAR IRREGULARITY OF THE OUTPUT OF VOLCANIC PRODUCTS

Gusev A.A.; Ponomareva V.V.; Braitseva O.A.; Melekestsev I.V.; Sulerzhitsky L.D. (2003)

Temporal irregularity of the output of volcanic material is studied for the sequence of large (V ≥ 0.5 km3, N = 29) explosive eruptions on Kamchatka during the last 10,000 years. Informally, volcanic productivity looks ...
Highly silicic glasses in peridotite xenoliths from Avacha volcano, Kamchatka arc; implications for melting and metasomatism within the sub-arc mantle

Ishimaru Satoko; Arai Shoji (2009)

Silicate glasses in peridotite xenoliths from Avacha volcano have high SiO2 (up to 72 wt.) and highly SiO2-oversaturated characteristics; normative quartz content is up to 50 wt.. The glasses represent secondary melts ...
Historical eruptions of Avacha volcano, Kamchatka. Attempt of modern interpretation and classification for long-term prediction of the types and parameters of future eruptions. Part 1 (1737-1909)

Melekestsev I.V.; Braitseva O.A.; Dvigalo V.N.; Bazanova L.I. (1994)

Some of the previous views on the style of the Avacha eruptions during 1737-1909 are revised on the basis of new data obtained by the authors. The types of eruptions, their geological and geomorphological effects, and the ...
