Reviewer 2 Report

The reviewer would like to thank the authors for this thoughtful manuscript. This work has good potential. The authors are requested to put in some additional efforts to improve the quality of this manuscript. 

 

Introduction 

The authors are requested to elaborate on how such techniques can help in early response of natural disaster related events observed with remote sensing. Please cite the following article that reports a major disaster and discuss how such an event can benefit from the proposed methodology for detecting sliding mountain edges. The event largely impacted the local human livelihoods as well as manmade infrastructure. How can emergency communication networks help in pre and post-disaster management?
