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 ...

ERUPTIVE HISTORY OF KARYMSKY VOLCANO, KAMCHATKA, USSR, BASED ON TEPHRA STRATIGRAPHY AND 14C DATING Braitseva O.A.; Melekestsev I.V. (1991)Eruptions of the active Karymsky stratovolcano began about 5300 (6100 C-14) B.P. from within a pre-existing caldera which formed 7700 C-14 B.P. As indicated by 32 C-14 determinations on buried soils and charcoal, the volcano ...

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 ...

Bursik M.; Melekestsev I.V.; Braitseva O.A. (1993)Three of four Plinian eruptions from Ksudach Volcano are among the four largest explosive eruptions in southern Kamchatka during the past 2000 years. The earliest of the eruptions was voluminous and was accompanied by an ...

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.
