Проведены работы, нацеленные на контроль качества полученных функций кросс-корреляции. Выявлены изменения частотно-амплитудных характеристик кросс-корреляционных функций на малых временах, а также смещения выявленных фаз на больших временах. Такого рода вариации характера кросс-корреляции могут указывать на наличие периодов с существенно различным характером сейсмичности и значительными вариациями механических свойств пород под вулканом. Это, в свою очередь, говорит о продолжающейся активности магматической системы вулкана Камбальный.</p></abstract><trans-abstract xml:lang="en"><p>Using experimental data obtained from the network of stations installed on Kambalny volcano in the period from July 2018 to July 2019, a set of correlation functions was obtained and its preliminary interpretation was carried out. Works aimed at quality control of the obtained cross-correlation functions have been performed. We have identified considerable variations of the frequency-amplitude characteristics of the cross-correlation functions at small times, as well as significant shifts of the derived phases in large correlation times. Such variations of the cross-correlation patterns may indicate the existence of distinct time periods with different types of seismicity, as well as strong variations of mechanical properties of rocks. In turn, this might be an evidence for the ongoing activity of the magmatic system beneath the Kambalny volcano.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхностные волны</kwd><kwd>шумовая томография</kwd><kwd>кросс-корреляция</kwd><kwd>сейсмическая сеть</kwd><kwd>мониторинг</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surface waves</kwd><kwd>ambient noise tomography</kwd><kwd>cross-correlation</kwd><kwd>seismic network</kwd><kwd>monitoring</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данное исследование поддержано грантом РНФ 20-17-00075.</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">Гирина О.А., Мельников Д.В., Маневич А.Г., Нуждаев А.А.
