Dear Authors, based upon the referees comments, the article needs major revision. Please consider carefully all indications and suggestions from the referees when submitting your revised version of the manuscript

Dear Authors,
as you can see from the reviewers reports, the article is considered as definitely improved, but there are still some minor revisions to be done before acceptance. Please refer particularly to the comments by Referee #2 when preparing the revised manuscript.
In detail, I agree with the indication not to use the term "hydrogeological", and as a further alternative to what indicated by Referee #2, I suggest "geo-hydrological". In any case the use of "hydrogeological" is definitely misleading for an international audience.
Further, I also suggest, in the initial part of the article to provide more references to some projects which have been important in Italy as concerns the issue of identification of rainfall thresholds for shallow landslides. At this regard, I suggest the work by Rossi et al. (2012), as the first contribution of a nation-wide project on this theme, and a few other references such as Melillo et al. (2018) and references therein. My suggestions are listed below.

I am looking forward to receiving the revised manuscript.

Dear Authors, we thank you very much for your revision of the article, prepared according to the reviewers and Editor suggestions. There is only one remaining thing, since we have realized that the added reference by Rossi et al. (2912) is incomplete (there is no reference to the book/proceedings where it was published, and the list of authors is incomplete as well). This is the only correction required before definitely accepting the paper.
The correction (with the complete reference) is shown in the attached file).
