This paper is relevant for the special issue, and provides an enrichment to other papers on Russia or database development.
As you know, two reviewers have provided detailed reviews, which you have replied in thoughtful detail to. Both reviewers recommended major revisions, and their views coincide. Answering those requests increases the value of the paper. I support these views. Therefore I would like to invite you to submit a major revised version of your manuscript. Would you please also provide an ‘author’s reply’ to the reviewers (feel free to use the same words that you used in what you have already uploaded). Please can you also include a track changes document between the old manuscript and the new one (you can include this as part of your ‘author’s reply’).

I thank the referees for thourough comments and the author for responding to those comments.
I have some observations before the paper can be published:
- referee #1 comments on why the proposed classification was preferred to other published schemes. Although the author's response is convincing, I suggest to include in the references some published schemes for comparison.
- line 189-210 (database description). I suggest to include a graphic showing the relational structure of the database. This is very useful in papers dealing with databases.
- the definition of vulnerability and risk as considered in this study should be moved more to the begin of the methodology section.
- which was the collection method of the author, which were the sources (media, archives, data of municipalities)? This should be briefly mentioned. How difficult are they to be accessed? Who can access them?
I welcome the author's answer regarding hazard maps, as it was a comment I would have otherwise made.

I thank the author for the implemented changes and highlights. I welcome especially the additions on the database structure as table and with the reference to the sources. As a minor correction something on the software for the database could be added. Looking forward to see it published!
