Research on the Response Characteristics and Identification of Infrasound Signals in the Jialongcuo Ice Avalanche, Tibet

Round 1

Reviewer 1 Report

The infrasound monitoring of ice avalanches can make up for the 106 deficiency of remote sensing technology and realize real-time monitoring of ice avalanche disasters. It is an interesting research to use infrasound sensor to monitor ice avalanche in real time. Good experimental setting and quantitative analysis were carried out in this study, and the results support the relevant conclusions.  

As there are few ice avalanches actually monitored, the conclusions of this study may not be universal. It is necessary to construct more ice avalanche infrasound monitoring arrays.

Reviewer 2 Report

The main question of the research is the characteristics and classification and recognition of infrasound signals from glacier ice avalanches.

In general, the topic is original and relevant and does not address any gap. in the field of remote sensing.

This research tests the effect of the infrasound signals of the ice avalanche and presents a new method of avalanche measurements.

The specific modifications should the author consider are:

1.      The title should be concise yet descriptive enough to accurately represent the content of the paper.

2.      Consider incorporating the key findings derived from the results into the Abstract, along with a brief overview of your interpretations and conclusions.

3.      The method section of the paper appears lengthy due to the excessive inclusion of intricate details and explanations. Consider revising it for better clarity and conciseness.

The conclusion summarizes all the evidence and arguments presented in the manuscript; the reference is appropriate.

The maps and graphs expressed very well the result of the paper.

Infrasound signal preprocessing, （3）Filtering, pag. 13, rows: 280-281: in the sentence “As only the signals no more than 20Hz in frequency were analyzed in this study, signals larger than 20Hz in frequency need to be removed through filtering.”: please explain and comment why only the signals less than 20Hz in frequency were analyzed.

In chp. 2. Methods, subchp. 2.3.3. Class recognition method, pag. 20, rows559-562: in the sentence “As the main purpose of class identification is to identify disaster events, and this study focuses on ice avalanche disasters, the three types of events were given different weights: ice avalanche events 0.5, flood events 0.4, wind and rain events 0.1, and the comprehensive index of each classification model was calculated. “: please define/describe the comprehensive index of each classification model.

In chp. 4. Conclusions and future prospects, pag. 691: Please mention that, since it is impossible to determine accurately that abnormal events monitored are ice avalanche events, the infrasound-based ice avalanche monitoring technology is closely related with a video surveillance system.
