Characterizing Crustal Deformation of the Weihe Fault, Weihe Basin (Central China), Using InSAR and GNSS Observations
Round 1
Reviewer 1 Report
I read the paper “Characterizing Crustal Deformation of the Weihe Fault, Weihe Basin (Central China), Using InSAR and GNSS Observations” by Tian et al. The investigated topic is very interesting and the authors proposed a set of analyses from Sentinel-1 satellites (InSAR) and GNSS. I found it is a very interesting the topic, generally, I think the analyses are properly conducted and conclusions are supported by the results, so the paper is worthy of publication in Applied Sciences. Anyway, I have several questions and I think the paper can be still improved.
(1) In 3.1, The authors should explain clearly how to remove orbital errors, terrain related atmospheric delay errors, those are of long wavelength signals
(2) In 3.2, Three-dimensional Deformation Rate by integrating of GNSS and InSAR, but in fact, the results of leveling are more reliable in the vertical direction, why is there no use of leveling results in this part.
（3） In 3.3 Geometric properties of the spherical-triangular grids. Is this method universally applicable and can this set of parameters be used in other parts of the world.
The article needs further polishing

Reviewer 2 Report
The manuscript is well presented and written with clear statement of objectives, methodologies adopted and key findings of the research, making it easy for readers to understand the significance of the study. I am sure the findings from the study will be useful to come up with risk mitigation measures in this seismically vulnerable area. I wish the authors all the best.

Significance of this study should be highlighted first.
Earthquake of 70-80% is very general. Please specify since when.
