The orographic factor in the Todzha Basin caused the development of thick shield glaciers covering the area of approximately 13 000 km<sup>2</sup> during cold epochs.</p><p id="idm45181324713904">The variety of geomorphological units reflecting the history of neotectonic evolution, volcanism and Quarternary glaciations creates a unique opportunity to perform paleogeographic reconstructions. The geomorphological map is constructed based on the selection of genetically homogeneous surfaces. Morphometrical indicators, paragenesis and time series were obtained for the later. A special attention was paid to the relief of intraglacial volcanoes and traces of glaciations of different ages.</p><p id="idm45181324718960">The lower level of intraglacial volcanoes formed in the second half of the Late Pleistocene was subdivided into three levels. These volcanoes formed under a few hundreds of meters of ice. The glacial-exaration genesis of microrelief under the influence of the inland ice was established as appose to the previously accepted water-glacial (catafluvial) genesis. The age of the upper slopes of volcanoes (except the Derbi-Taiga volcano) is the Late Pleistocene. Consequently, glacial valleys and kars complicating them are rejuvenated .</p><p id="idm45181324728336">The study of the rockfall bodies triggered by an earthquake and rockfalls rupture surfaces in glacial valleys of the Derbi-Taiga mountain massif and their comparison with the traces of the Chuya earthquake (2003) allowed to estimate the Ms = 7.5 magnitude of the Holocene earthquake that caused them.</p><p id="idm45181324735984">Presented results of the geomorphological investigation contradict the paleogeographic reconstructions performed earlier on the basis of absolute dating.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324703040">Азасское плато в Алтае-Саянской горной области является единственной территорией в умеренных широтах континентальной Евразии, где выявлены внутриледные вулканы, образованные при взаимодействии извергающейся лавы со льдом и талыми водами. Орографический фактор в Тоджинской котловине обусловливал развитие в холодные эпохи мощных покровных ледников, площадь которых оценена в 13 тыс. км<sup>2</sup>. Разнообразие геоморфологических единиц, отражающих историю неотектонического развития, вулканизма и оледенений квартера создает уникальную возможность для выполнения палеогеографических реконструкций. Построена геоморфологическая карта на основе выделения генетически однородных поверхностей. Для последних получены морфометрические показатели, парагенезисы и временные ряды, особое внимание уделено рельефу внутриледных вулканов и следам разновозрастных оледенений.</p><p id="idm45181324711008">Установлено трехуровневое строение нижнего яруса внутриледных вулканов, формировавшихся во второй половине позднего плейстоцена при толщине ледового покрова в первые сотни метров; обоснован ледниково-экзарационный генезис микрорельефа, который ранее считался водно-ледниковым (катафлювиальным); возраст склонов вулканов верхнего яруса (за исключением вулкана Дерби-Тайга) ограничен поздним неоплейстоценом и, соответственно, омоложены осложняющие их ледниковые долины и кары. Изучение тел сейсмообвалов и стенок отрыва в ледниковых долинах горного массива Дерби-Тайга и сопоставление их со следами Чуйского землетрясения (2003 г.) позволяет оценить магнитуду вызвавшего их голоценового землетрясения как M<sub>s</sub> = 7.5. Выявлены противоречия результатов геоморфологических исследований палеогеографической картины, восстанавливаемой на основе лишь абсолютных датировок.</p></trans-abstract><kwd-group xml:lang="en"><kwd>genetically homogeneous planation surfaces</kwd><kwd>tuya</kwd><kwd>intraglacial volcanoes</kwd><kwd>inland ice</kwd><kwd>seismic rockfall</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>генетически однородные поверхности</kwd><kwd>туйя</kwd><kwd>покровное оледенение</kwd><kwd>сейсмообвал</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">The work was carried out according to the state tasks of Tuvinian Institute for Exploration of Natural Resources of Siberian Branch of RAS (FUFS-2021-0002), Sobolevs Institute of Geology and Mineralogy of Siberian Branch of RAS (FWZN-2022-0036), field research with the support of RFBR (project No. 20-05-00605).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Allen C.C., Jercinovic M.J., Allen J.S.B.
