В первой серии моделировалось саморазвивающееся погружение слэба при исходных кинематических и физических параметрах зоны субдукции. Во второй серии дополнительно введен и протестирован новый элемент региональной модели субдукции — зона кинематической стабилизации в астеносферной мантии для обеспечения более пологой траектории погружения слэба. В первой серии численных экспериментов (без зоны стабилизации) была получена крутопадающая субдукция, не соответствующая конфигурации слэба по имеющимся геофизическим данным, при полном отсутствии магматизма в течение первых 14 млн лет модельного времени. Во второй серии (с зоной стабилизации) была воспроизведена конфигурация слэба по данным сейсмотомографии и построены P–T тренды (геотермы) для поверхности слэба и подошвы океанической коры (граница Мохо). Проявления вулканизма во второй серии наблюдались, начиная с 9 млн лет модельного времени. Вулканизм по составу преимущественно кислый, вулканические постройки находятся на удалении 200 км от желоба, последнее в целом соответствует пространственному расположению Восточного вулканического пояса по отношению к желобу.</p></abstract><trans-abstract xml:lang="en"><p>   Two series of numerical experiments were conducted simulating the initiation and evolution of the subduction of the Pacific plate beneath the Northern segment of Kamchatka subduction zone. In the first series, the self-developing submergence of the slab was modeled with the initial kinematic and physical parameters of the Kamchatka subduction zone. In the second series, a new element of the regional subduction model was introduced and tested — a zone of kinematic stabilization in the asthenospheric mantle to ensure a shallower trajectory of slab submergence. In the first series of numerical experiments (without the stabilization zone), a steeply dipping subduction not corresponding to the slab configuration according to existing geophysical data was obtained, with complete absence of magmatism during the first 14 million years of model time. In the second series (with the stabilization zone), the slab configuration according to seismotomography data was reproduced, and P-T trends (geotherms) for the surface of the slab and the base of the oceanic crust (Moho boundary) were constructed. Manifestations of volcanism in the second series were observed starting from 9 million years. The volcanism is predominantly acidic in composition, and volcanic structures are located at a distance of 200 km from the trench, which corresponds to the spatial arrangement of the East Kamchatka volcanic belt relative to the trench.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Камчатский полуостров</kwd><kwd>численное моделирование</kwd><kwd>геодинамика</kwd><kwd>субдукция</kwd><kwd>магматизм</kwd><kwd>геотерма</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Kamchatka Peninsula</kwd><kwd>numerical modelling</kwd><kwd>geodynamics</kwd><kwd>subduction</kwd><kwd>magmatism</kwd><kwd>geotherm</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке РНФ (проект № 23-17-00066) и с использованием оборудования Центра коллективного пользования сверхвысокопроизводительными вычислительными ресурсами МГУ имени М.В.
