The preparation of a harmonized earthquake catalogue and a database of active faults for a given region, in this case Central Asia, are important steps to achieve a probabilistic earthquake risk assessment.  The authors have carried out a comprehensive work, involving experts for the local scientific community in the framework of a regional program involving risk management and mitigation. The study is very important for the scientific community as the the main objective was to create a preparatory collection of data based on the most complete and up-to-date information available for the territory, consistent and uniform for all Central Asian countries. I strongly recommend this article for publication, maybe with some minor revisions:

• the term homogenized instead of harmonized or explained what it means “harmonized“ in “earthquake catalog harmonized between countries”.
• At L 80 there is a statement - “including the description of intensity in moment magnitudes (Mw) “. I do not know formulas of Mw which include the seismic intensity, I, maybe it is better to give an example of a formula or exclude this statement if there is not the case.
• L350, L380 - reference to an annex to the reliability classes of faults.
• L390 instead of “The homogenization of input datasets“ … maybe “The harmonization of input datasets“. The terms seems synonyms.
• L395 instead of a “top-down approach“ maybe a “general-particular (detailed) approach“.
