Round 1

Reviewer 1 Report

The case studies analyzed are clear and highlight how useful optical satellite images can be in monitoring subglacial volcanic activity or in case interacting with glaciers. This is not a new topic, but the organized discussion of the topic at a planetary scale certainly represents an excellent synthesis of the potential of this type of satellite analysis applied to the evolution of glaciers that interact with volcanic activity; on the other hand, this analysis inherits the experience of studies conducted on other natural phenomena and on different geological contexts, and therefore starts from a knowledge base that allows to correctly evaluate the strengths and weaknesses of the method, including its application limits that cannot be overcome by current technologies.

Perhaps the authors could further emphasize the usefulness of their study in terms of assessing the hazard associated with the formation of lahars produced by the melting of a portion of a glacier, which in the past caused very significant disasters.

Overall, my opinion is very positive and I think the article is ready to be published on Remote Sensing.
