В монографии впервые детально рассмотрена проблема вулканического рельефообразования. На примере Курило-Камчатской и других молодых вулканических областей подробно проанализирована роль вулканизма в формировании рельефа в современную эпоху и в антропогене. Дано принципиально новое представление о морфоструктуре Курило-Камчатской области и других родственных им образований переходных зон от океана к континенту. Сделан вывод о том, что главные этапы развития вулканического рельеф служат индикатором глубинных процессов определенных стадий геологической эволюции Земли.

We show that the terrestrial land and seafloor contain no volcano-tectonic mega landforms expressed in relief that could be similar in size to those identified on Mars, and could have analogous structure and origin to the giant landforms whose volumes of constituent rocks are (1-2.4) x 106 km3 (Alba Patera, Olympus Mons, Arsia Mons, Ascraeus Mons, Pavonis Mons, and Elysium Mons). No fragments or traces of similar features have ever been unambiguously identified and described in geological rock sequences, not only in Mesozoic and Cenozoic rock sequences, but also in those dating back to Paleozoic time. The same applies to the older epochs on Earth. Now the topographic constituent components of Martian mega landforms have the appearance of very magnified copies of well-known and repeatedly described terrestrial volcanic edifices, viz., dominantly shield-like and lava volcanoes, lava domes, as well as calderas of various types. However, the edifices of the above types of volcanoes are not identical with their Martian counterparts as to morphology, being shorter in height and having steeper slopes. The calderas are smaller by factors of multiple times. The Martian volcanic landforms are much older. There is a unique edifice, namely, Olympus Mons, a mega land-form that stands in a large glacier sheet and for whose origin glacial processes are also responsible. It is classified as belonging to the type of giant tuyas. Its mini analogues are glacial subaerial tuyas of different ages and parameters that have been subjected to glaciation in volcanic areas on Earth.

Mount Rannyaya (86°58' S, 163°20' W, 2270 m a.s.l., 18-20 Ма) и Sheridan Bluff (87°04' S, 153°46' W, 2720 m a.s.l., ~ 16 Ма) were explored in 1934 and 1962-1963, and studied and dated in 1978-1979 bу Antarctic researches. The article shows that these volcanoes are typical tuya, the oldest and high-latitude volcanoes on Earth. It confirms that in early Miocene thick glaciers existed in western Antarctic near the Pole, and subglacial volcanic activity was strong.

Three stages of study of active and potentially active volcanoes on Kamchatka and the Kurile Islands were distinguished: the anterior stage (1700-1935), the new stage (1935-1962) and the recent stage (from 1962 till present time).
This paper provides a new, for the first time scientifically based term of «active volcano». Updated catalogues display active and potentially active volcanoes of Kamchatka and the Kurile Islands. Here we propose a long-term forecast of behavior and parameters of impending eruptions and related volcanic hazards for the typical volcanoes of the 1st and the 2nd stages of evolution.
