Comment to “Geomorphology of subaerial mud volcanoes in Azerbaijan: Issues about edifice construction and degradation”. Insights from 10Be dates for the Ayazakhtarma mud volcano

Abstract

In their article, Komatsu and Feyzullayev (2024) present a typology of mud volcanoes in Azebaijan, and discuss the temporal evolution of these volcanoes on a scale of a few years. We are adding new quantitative data, consisting in cosmonuclide ¹⁰Be data on Ayazakhtarma mud volcano (48.98°E, 40.37°N). Such analyses show the evolution of the volcano on the scale of 100 years and reveal two important points. (i) The central part of the volcano is built via significant vertical mobility, which leads to a homogeneous cosmogenic signal. (ii) The medial/external parts record the enlargement of the edifice, which takes at least 800 years. This age could correspond to the last major eruption or a continuous expansion at a maximum growing rate of 87 cm/yr.
