The old views on the style of the Avachinsky eruptions during 1737- 1909 have partially been revised based on new data obtained by the authors. We specified their types and geological-geomorphological effect and made an assessment of the related volcanic hazards. All the eruptions were merely explosive except for the effusive-explosive eruption of 1894-1895. The eruptions of 1737, 1779 and 1827 are referred to large for this historical eruptive stage, the rest (of 1772, 1851-1855, 1878, 1881, 1894-1895 and 1909) are regarded as small and moderate.

We have summed up and supplemented new data on the eruptions of 1926-1927, 1938 and 1945 plus added the description of the last eruption of the volcano in January 1991. Considering the dynamics of the eruptive activity of the Avachinsky volcano in 1737-1991 we have presented a classification for these eruptions. Also we made a forecast of the type and parameters of possible future eruption as well as estimated the volcanic hazard associated with it. Because of high degree of volcanic hazard in the SW and S sectors of the base of the volcano it is proposed to prohibit constructions of any kind in these areas.

A new approach to definition of the term "active volcano" has been worked out on the basis of detailed reconstruction of the eruptive activity of Kamchatka volcanoes. We suggest to consider active those poligenous volcanoes whose at least a single eruption has been ascertained and dated over the last 3000-3500. Two sub-groups of active volcanoes have been distinguished: sub-group of active volcanoes with data available on the historically documented eruptions or fumarolic activity and the one of potentially active volcanoes without such data but whose eruptions have been revealed over the last 3500 years. Using similar criteria the potentially active fields of the areal basalt volcanism, regional zones of cinder cones and concentrated manifestation of the multivent extrusive volcanism are also distinguished. We propose to use data obtained for the new catalogue of active Kamchatka volcanoes and for the long-term prediction of volcanic activity and associated hazard.

We have identified, and describe in this paper, a phase of multifactor natural catastrophism that has been the greatest during our era in Kamchatka, to be dated 0-650 A. D. Its chief components were. The last catastrophic eruptions to have occurred (a caldera-generating one at about 240 A. D., the pyroclastics volume being 18-19 km3 and a subcaldera one around 600 A. D. with the volume of lava and pyroclastics 9.5-10.5 km3) which were followed by irreversible relief changes over areas of hundreds of square kilometers and have affected rather injuriously many other environmental components. An exceptionally intensive activity of the other volcanoes (at least 75-80% of all active and potebtially active Kamchatkan volcanoes were erupting, tens of large and catastrophic eruptions occurred). Regional catastrophic and large ashfalls. A sharp, large-amplitude (between 1.5-2 and 12-15 m) tectonic uplift of various blocks in Kamchatka. Large earthquakes accompanied by large-volume rockfalls, landslides, large and frequent tsunamis. The catastrophic events of that time are argued to have been part of a worldwide phase of natural catastrophism that we hypothesize to have occurred at the beginning of our era.

Theories are presented about the time of origin, dynamics and formation mechanism of active volcanoes in the Kuril-Kamchatka zone during the Late Pleistocene-Holocene period. The study was based on more than 500 radiocarbon dates and the results of geological, geomorphological, tephrochronological and isotopic geochronological research. It is noted that there are different rhythms in the activity of the volcanoes and in the mechanisms and rates of formation of the volcanic structures. Periods of synchronous activity of the volcanoes on Kamchatka and the Kuril islands, and apparently, in other volcanic areas are identified, suggesting their global nature. The concept of "active volcano' is discussed. -P.Cooke

Four Plinian eruptions from Ksudach volcano ha' been reconstructed and dated by the 14C method. Three collapse calderas formed as a resu of these eruptions: KSi and caldera V 1700-1800 yrs ago; KS2 + KS3 and caldera IV 6000- 6100 yrs ago; KS4 and caldera III 8700-8800 yrs ago. KSi was the most voluminous eruptio with 18-19 km of pyroclastics and column height reaching 23 km. The volume of produci of KS2 + KS3 was 10-11 km3 and that of KS4, at least 1.5-1.7 km3. Sizes of calderas wer as follows: V - 4 X 6.5 km, IV - 5x5 km, III - presumably 2-3 km across. The juveni pyroclastics were supplied during eruptions rather rhythmically. Each rhythm began wil tephra ejection and completed with the formation of pyroclastic flows. The composition < products varied from andesited to rhyodacites: KS2 and KS4 - andesites dominated, KS3 - dacites and rhyodacites, and KSi - rhyodacites. It is possible that "the mechanism triggering onsets of all caldera-forming eruptions was the intrusion of very hot fresh magma of basi composition and its mixing with less hotter acid magma in the magma chamber existe previously. The eruptions, in accordance with their scales, may have had an impact on clima and ozone layer of the Earth. It is likely that the large acidity peaks in Greenland ice cor* result from these eruptions.
