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 km3), are widespread. Moreover, these processes are among the most effective and most rapid geomorphic agents. Of 30 recently active Kamchatka volcanoes, at least 18 have experienced sector collapses, some of them repetitively. The largest sector collapses identified so far on Kamchatka volcanoes, with volumes of 20–30 km3 of resulting debris-avalanche deposits, occurred at Shiveluch and Avachinsky volcanoes in the Late Pleistocene. During the last 10,000 yr the most voluminous sector collapses have occurred on extinct Kamen' (4–6 km3) and active Kambalny (5–10 km3) volcanoes. The largest number of repetitive debris avalanches (> 10 during just the Holocene) has occurred at Shiveluch volcano. Landslides from the volcanoes cut by ring-faults of the large collapse calderas were ubiquitous. Large failures have happened on both mafic and silicic volcanoes, mostly related to volcanic activity. Orientation of collapse craters is controlled by local tectonic stress fields rather than regional fault systems.

Specific features of some debris avalanche deposits are toreva blocks — huge almost intact fragments of volcanic edifices involved in the failure; some have been erroneously mapped as individual volcanoes. One of the largest toreva blocks is Mt. Monastyr' — a ∼ 2 km3 piece of Avachinsky Somma involved in a major sector collapse 30–40 ka BP.

Long-term forecast of sector collapses on Kliuchevskoi, Koriaksky, Young Cone of Avachinsky and some other volcanoes highlights the importance of closer studies of their structure and stability.

This impressive scientific resource presents up-to-date information on ten thousand years of volcanic activity on Earth. In the decade and a half since the previous edition was published new studies have refined assessments of the ages of many volcanoes, and several thousand new eruptions have been documented. This edition updates the book's key components: a directory of volcanoes active during the Holocene; a chronology of eruptions over the past ten thousand years; a gazetteer of volcano names, synonyms, and subsidiary features; an extensive list of references; and an introduction placing these data in context. This edition also includes new photographs, data on the most common rock types forming each volcano, information on population densities near volcanoes, and other features, making it the most comprehensive source available on Earth's dynamic volcanism.

Kharchinsky and Zarechnyi volcanoes - unique centers of late Pleistocene magnesian basalts in Kamchatka: Structural setting, morphology, geologic structure and age // Volcanology and Seismology. 1999. V. 20. № 4-5. P. 383-399.    Annotation
This paper presents the results of studying the spatial distribution and structural setting of magnesian basalts and andesites in the Northern group of Kamchatkan volcanoes and in the junction zone of the Kuril-Kamchatka and Aleutian island arcs. The morphology and geologic structure of unique Kamchatkan magnesian basalt stratovolcanoes are described: Kharchinsky, Zarechnyi, and the Kharchinsky regional zone of cinder cones. The reported evidence includes the ages and eruptive histories, and productivities of the volcanoes and the volumes and weights of their edifices. The magnesian basalts were erupted 40-50 thousand years ago, for the first time during the Holocene.

Most of the Kharchinskii and Zarechnyi products, as well as those of the Kharchinskii cinder cones, are magnesian rocks. Mineralogical data suggest that both the basaltic and the andesitic magma were rich in water (≥3-4 and >6-7 wt., respectively) and crystallized at high oxygen fugacity (2.0-2.5 orders of magnitude higher than the NNO buffer). These features, coupled with the geochemical characteristics of these basalts and andesites, indicate that they are similar to the rocks of Shiveluch, a volcano also located on the northern flank of the Northern volcanic group, but differ from the rocks of the other volcanoes of this group which are located further south. The Kharchinskii, Zarechnyi, and Shiveluch magnesian basalts differ from the rocks of the Klyuchevskoi volcano and Tolbachik lava field by their higher K, Ba, Sr and lower Ca, Sc, Yb contents at higher La/Yb, Ni/Sc, and La/Ta ratios, while their initial magmas were more hydrous and more oxidized.

Подавляющая часть пород Харчинского и Заречного вулканов, а также Харчинской зоны шлаковых конусов принадлежит к магнезиальному типу. Судя по минералогическим данным, и базальтовые и андезитовые расплавы отличались высоким содержанием воды (>3-4 и >6-7 мас.% соответственно) и кристаллизовались при высокой (на 2.0-2,5 порядка выше буфера NNO) футигитивности кислорода. В этом отношении, а также по особенностям валового химического и редкоэлементного состава базальты и андезиты изученных вулканов весьма близки породам вулкана Шивелуч,также расположенного на северном фланге Северной группы вулканов Камчатки, но отличаются от таковых более южных вулканов группы. Магнезиальные базальты вулканов Харчинский, Заречный и Шивелуч по сравнению с аналогичными по магнезиальности базальтами Ключевского вулкана и Толбачинского дола имеют более высокие концентрации К, Ва, Sr, более низкие Са, Sc, Yb при более высоких отношениях La/Yb, Ni/Sc и La/Та, а исходные расплавы их были более водонасыщенными и окисленными.

С. 5-18.    Annotation
Рассмотрены особенности пространственного распределения и структурная позиция проявлений магнезиальных базальтов и андезитов в пределах Северной группы вулканов Камчатки и зоны сочленения Курило-Камчатской и Алеутской островодужных систем. Описаны морфология и геологическое строение нигде более не встречающихся на Камчатке многоактных вулканов Харчинский и Заречный, сложенных магнезиальными базальтами, а также Харчинской региональной зоны шлаковых конусов. Приведены сведения об их возрасте и истории формирования. Определены объем и вес пород вулканических построек (не менее 75-83 км3 и (185...205) ¦ 109 т), оценена их продуктивность. Обращено внимание на молодость (последние 40-50 тыс. лет) извержений магнезиальных пород на территории Северной группы вулканов и сопредельных участках, а также на то, что это произошло здесь впервые за антропоген.
