Dear Authors,
your manuscript submitted to NHESS can potentially be published in our journal, provided that some major revisions as indicated in the reviewer reports can successfully be applied.
To proceed with the closed peer-review process, please resubmit you revised manuscript together with a version in track change mode highlighting the applied changes and a detailed point-per-point reply on the reviewer comments. After resubmission, your manuscript will be reviewed again by one referee and the editor.
Best regards, A. Günther

Dear Authors,
Referee #2 who initially wanted to review your paper again after resubmission did not respond to my second call. Reading your revised submission I think you convincingly replied to the concerns of the reviewers and substantially reworked your manuscript according to these. Therefore, there is no need to involve a third referee into this process and I am pleased to inform you your manuscript can now be accepted for publication in NHESS. Below you find some technical observations I made when reading your paper, which you may consider before final submission.
Best regards, A. Günther

P2, l 27: „traveled down the slope by rockfall mechanism“: Maybe omit „rockfall mechanism“ since the blocks not only travelled by falling?
P2, l27: “pre-town aerial photos” maybe rephrase to “aerial photos before urbanization” or similar.
P3, l6-19: It would be really nice to show some simple size histogram distribution of the measured blocks to illustrate what is written in this paragraph, maybe to be combined with Figure3.
P3, l 24: “a-seismic” -> aseismic
P7, l27: “Thus” -> This
P7, l31: “current study” -> this study
P8, l11: “occurred” -> they occured

Figures:
Figure 1: In the caption, what is meant with “backdrop”? Backscarp? Please be clear.
Figure 2: The photo has no orientation. If possible, it would be nice to plot the location in Figure 1 b.
Figure 4: There are some instances in the map that are not in the legend: A dashed line (supposed fault?), lines with stipples (normal faults?), lines with triangles (landslide scarps?). Another point may be to label the simulation scan lines for better comparision with Figure 7.
Figure 7: Maybe it would be good to plot both the 1-degree intervals for the radial slope angle axis and the 1 profile-intervals of the x-axis in thin gray lines for a better reading of this interesting diagram?
