Для района исследований по данным 2019–2020 гг. плотной сети из 33 временных и 14 постоянных станций рассчитаны значения толщины земной коры и усредненные значения отношения VP/VS. Для определения глубины коро-мантийной границы (Мохоровичича, Мохо) использовался метод приемных функций, основанный на анализе разницы времен прихода прямой и обменных фаз сейсмических волн от телесейсмических событий. Инверсия приемных функций осуществлялась методом сеточного поиска в координатах H (толщины земной коры) и k (отношения VP/VS), в предположении, что земная кора – это однородный изотропный слой, лежащий на полупространстве. Результаты показали, что глубина границы Мохоровичича варьирует в пределах 30–35 км под станциями, расположенными в центральной области Камчатки с заглублением до 40 км в районе вулкана Авачинский. Для станций временной сети, установленной силами сотрудников ИНГГ СО РАН, и большинства привлеченных станций постоянной сети КФ ФИЦ ГС РАН результат получен впервые и в зонах пересечения согласуется с выводами в ранее опубликованных работах других авторов.</p></abstract><trans-abstract xml:lang="en"><p>The work is devoted to the study of the heterogeneity of the boundary of the Earth's crust and mantle in the central region of the Kamchatka Peninsula. For the research area, according to a dense network of 33 temporary and 14 permanent stations for 2019–2020, the values of the thickness of the Earth's crust and the average VP/VS ratio were calculated. To determine the depth of the crust-mantle boundary (Moho), the receiver function method was used, based on the analysis of the difference in the arrival time of direct and exchange phases of seismic waves from teleseismic events. The inversion of the receiver functions was carried out using the grid search method in the coordinates H (crust thickness) and k (VP/VS ratio), assuming that the crust is a homogeneous isotropic layer on a half-space. The results showed that the Moho depth ranges from 30–35 km under the stations in the Kamchatka central region, with a deepening to 40 km in the area of the Avacha Volcano. For the stations of the temporary network that were set up by the IPGG SB RAS staff, and most of the stations of the KB GS RAS permanent network, the result was obtained for the first time and in the intersection areas is consistent with the conclusions contained in previously published works by other authors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сейсмология</kwd><kwd>граница Мохоровичича</kwd><kwd>метод приемных функций</kwd><kwd>обменные продольные и поперечные волны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>seismology</kwd><kwd>Moho boundary</kwd><kwd>receiver function method</kwd><kwd>transformation of seismic P- and S-waves</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>исследование выполнено по плану базовых научно-исследовательских работ ИНГГ СО РАН (проект Минобрнауки РФ FWZZ-2022-0017).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was carried out as part of government assignment to the Russian Academy of Sciences in basic research, Project FWZZ-2022-0017.</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">Авдейко Г.П., Савельев Д.П., Попруженко С.В., Палуева А.А.
