Для их решения использованы данные сейсмологии, инверсной сейсмотомографии на объемных Р-волнах и геоэлектрики, полученные в последние годы, а также сведения по магнитометрии, гравиметрии, тектонике и магматизму. На основе комплексного анализа геолого-геофизических данных установлено различие в строении земной коры и верхней мантии Северной и Южной Камчатки и показана общность глубинных структур Южной Камчатки и Курильских островов. Определена возможная граница между Северной и Южной Камчаткой, связанная с зоной поперечных глубинных разломов, пересекающих полуостров. Она проявляется в поведении скоростных аномалий на различных уровнях литосферы. С этой зоной связано изменение геометрии и простирания высокоскоростного фокального слоя. Данная разломная зона находит отражение в современном тектоническом плане в виде Петропавловск-Малкинской зоны поперечных дислокаций. Здесь расположена Авачинско-Корякская группа современных вулканов, также ориентированная в северо-западном направлении. Приводится глубинная геоэлектрическая модель по профилю, выполненному вкрест этой зоны. Глубинная часть модели содержит субвертикальные аномалии повышенной электропроводности. Они связываются с глубинными разломами. Повышенная электропроводность может быть обусловлена наличием магматических расплавов, питающих вулканы. Полученные результаты свидетельствуют об общности глубинных структур Южной Камчатки и Курильской островной дуги, а также о различии в глубинном строении Северной и Южной Камчатки, разделенных зоной разломов, возможно, проникающих в верхнюю мантию. Предполагается, что выявленные особенности в строении Южной Камчатки обусловлены глубинными процессами со стороны не только Тихого океана, но и южных окраин Охотского моря. Полученные результаты представляют интерес для геодинамики, вулканологии, тектоники и других наук о Земле.</p></abstract><trans-abstract xml:lang="en"><p>Differences have been discovered in the deep structures of North and South Kamchatka, which raises a question about a boundary between these regions. This problem has been studied on the basis of the seismologic, inverse seismic tomographic (P-waves) and geoelectrical data obtained in recent years, as well as the information on magnetometry, gravimetry, tectonics and magmatism of the study area. Comprehensive analysis of the geological and geophysical data shows differences in the structure of the crust and upper mantle in North and South Kamchatka and common features of the deep structures of South Kamchatka and the Kuril Islands. A presumed boundary between North and South Kamchatka is related to the zone of transverse deep faults crossing the peninsula. It is evidenced by P-wave velocity anomalies at different levels of the lithosphere. This fault zone is associated with a change in the geometry and strike of the high-velocity focal layer, and reflected in the modern tectonic plan as the Petropavlovsk-Malkinsky zone of transverse dislocations. In this zone, the Avacha-Koryak group of modern volcanoes is also NW-oriented. We propose a geoelectric model showing the depths along the profile constructed across the zone. In its deep part, the model includes sub-vertical anomalies of increased electrical conductivity. The anomalies are related to deep faults. Increased electrical conductivity may be due to the presence of magmatic melts feeding volcanoes. The results obtained in our study give evidence of the common features of the deep structures of South Kamchatka and the Kuril island arc and demonstrate the differences between the deep structures of North and South Kamchatka, being separated by the zone of faults, which may penetrate into the upper mantle. It is suggested that the identified features in the South Kamchatka structure are due to deep processes taking place not only at the side of the Pacific Ocean, but also at the southern margins of the Sea of Okhotsk. These findings are of interest for geodynamics, volcanology, tectonics and other Earth sciences.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сейсмология</kwd><kwd>сейсмотомография</kwd><kwd>геоэлектрика</kwd><kwd>скорость сейсмических волн</kwd><kwd>электропроводность</kwd><kwd>землетрясение</kwd><kwd>вулкан</kwd><kwd>гидротермальный раствор</kwd><kwd>магматический расплав</kwd></kwd-group><kwd-group xml:lang="en"><kwd>seismology</kwd><kwd>seismic tomography</kwd><kwd>geoelectrics</kwd><kwd>seismic velocity rate</kwd><kwd>electrical conductivity</kwd><kwd>earthquake</kwd><kwd>volcano</kwd><kwd>hydrothermal solution</kwd><kwd>magmatic melt</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">РФФИ, проект	 №	16‐05‐00059</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гнибиденко Г.С.
