Ponomareva V.V.; Kyle P.R.; Melekestsev I.V.; Rinkleff P.G.; Dirksen O.V.; Sulerzhitsky L.D.; Zaretskaia N.E.; Rourke R. (2004)The 7600 14C-year-old Kurile Lake caldera-forming eruption (KO) in southern Kamchatka, Russia, produced a 7-km-wide caldera now mostly filled by the Kurile Lake. The KO eruption has a conservatively estimated tephra volume ...

Braitseva O.A.; Melekestsev I.V.; Ponomareva V.V.; Sulerzhitskii L.D. (1995)The ages of most of calderas, large explosive craters and active volcanoes in the Kuril-Kamchatka region have been determined by extensive geological, geomorphological, tephrochronological and isotopic geochronological ...

Braitseva O.A.; Melekestsev I.V.; Ponomareva V.V.; Kirianov V.Y. (1996)The largest Plinian eruption of our era and the latest caldera-forming eruption in the Kuril-Kamchatka region occurred about cal. A.D. 240 from the Ksudach volcano. This catastrophic explosive eruption was similar in type ...

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 ...

Volynets O.N.; Ponomareva V.V.; Braitseva O.A.; Melekestsev I.V.; Chen C.H. (1999)The combination of geological, tephrochronological and geochemical studies is used to reconstruct the Holocene eruptive history of Ksudach volcanic massif, South Kamchatka and to trace the evolution of its magma. Ksudach ...

Braitseva O.A.; Ponomareva V.V.; Sulerzhitsky L.D.; Melekestsev I.V.; Bailey J. (1997)Detailed tephrochronological studies in Kamchatka Peninsula, Russia, permitted documentation of 24 Holocene key-marker tephra layers related to the largest explosive eruptions from 11 volcanic centers. Each layer was traced ...

Melekestsev I.V.; Ponomareva V.V.; Volynets O.N. (1995)We studied the tectonic setting, morphology, geologic structure, history of eruptive activity and evolution of the composition of the erupted material of Kizimen volcano, Kamchatka, from the moment of its origination 11–12 ...

Braitseva O.A.; Sulerzhitsky L.D.; Litasova S.N.; Melekestsev I.V.; Ponomareva V.V. (1993)We discuss results of 14C dates obtained from areas of young volcanoes in Kamchatka. We apply these dates to reconstructing regional volcanic activity during the Holocene.
-
Zaretskaya N.E.; Ponomareva V.V.; Sulerzhitsky L.D. (2007)Radiocarbon dating is widely used when studying recent volcanic activity in the Kamchatka Peninsula due to the abundance of organic matter that is associated with the volcanic deposits. Here, we present the results of 14C ...
-
Ponomareva V.V.; Melekestsev I.V.; Dirksen O.V. (2006)On Kamchatka, detailed geologic and geomorphologic mapping of young volcanic terrains and observations on historical eruptions reveal that landslides of various scales, from small (0.001 km3) to catastrophic (up to 20–30 ...
