Two reviewers have now provided detailed comments on your manuscript. They are both positive about the scientific interest of your study and the clarity of the writing. However, they have recommended that some specific points be clarified, particularly with regard to the methodology followed. I suggest that you address these points in particular, on the calculation and physical interpretation of the evolution of the b-value, before submitting a revised version of your manuscript, which should then represent a significant contribution to the field.

  Dear Dr. Pinel,
  we largely appreciate the comments and suggestions posted by both reviewers and tried to implement all of them in the new version of our manuscript. Particularly, we modified the method for b-value calculations by adapting our codes to the b-positive method of van der Elst (2021) as suggested by RC1, which had a significant impact on the computed b-value time series making our results more robust and interpretable. We also performed a deeper analysis of tremor polarization as also suggested by RC1. We also moved some figures from the supplementary material to the main text and created new figures as suggested by both reviewers. Particularly, we made an attempt to summarize our main results and constraints from previous authors in a conceptual scheme with time evolution of the main processes discussed in the text, as suggested by R2. All in all, we feel that the manuscript was greatly improved in its form and content and are very grateful to the reviewers and the editor.
  Hoping that you will appreciate the changes included in our work and looking forward to upload the final version of the manuscript,
  Andrés Tassara on behalf of the coauthors.

The paper represents a very detailed study of the geophysical precursors recorded before and during a major recent explosive eruption. Moreover, the results permit to partly validate and discuss recent models of volcano unrest and have large applications for the monitoring of hazardous volcanoes worldwide.
