Сопоставление полученных зависимостей добротности от частоты показывает, что затухание сейсмических волн выше в литосфере Тянь-Шаня, что может объясняться большей раздробленностью и неоднородностью среды по сравнению с Байкальским рифтом. </p></abstract><trans-abstract xml:lang="en"><p>Evaluation of seismic wave attenuation parameters (Q-factor and frequency parameter) in the lithosphere of the Tien Shan and the Baikal rift was carried out using coda waves of regional earthquakes. Comparison of obtained quality factor values shows that attenuation in the lithosphere of the Tien Shan is stronger than in the Baikal rift. It can be explained by a higher level of heterogeneity of medium. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>затухание</kwd><kwd>добротность</kwd><kwd>сейсмические волны</kwd><kwd>Байкальский рифт</kwd><kwd>Тянь-Шань</kwd></kwd-group><kwd-group xml:lang="en"><kwd>attenuation</kwd><kwd>quality factor</kwd><kwd>seismic waves</kwd><kwd>Baikal rift</kwd><kwd>Tien Shan</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Минобрнауки России (в рамках государственных заданий по темам НИР №075-01471-22, АААА-А21-121011890033-1) с использованием данных, полученных на УНУ «Сейсмоинфразвуковой комплекс мониторинга арктической криолитозоны и комплекс непрерывного сейсмического мониторинга Российской Федерации, сопредельных территорий и мира» и УНУ «Южно-Байкальский инструментальный комплекс для мониторинга опасных геодинамических процессов», входящей в состав ЦКП «Геодинамика и геохронология» Института земной коры СО РАН.
