Reviewer 2 Report

Comments and Suggestions for Authors

This paper introduced a combined underground-ground integrated microseismic monitoring and transient electromagnetic detection method for evaluation hydraulic fracturing effect. It has certain practical application value in engineering. Some comments for this paper:

1. Lines 80-83 already describe the evaluation of the effectiveness of hydraulic fracturing using a joint approach; would lines 84 through 85 be redundant? Perhaps you mean to express that the two sections respectively involve the use of passive CT imaging and localization results?

2. Please identify the units and physical meanings of the color bar in the fig.1.

3. In Figure 16, what physical information does the color represent? What are the units? How do you get  graph a and b? Is it only possible to obtain graph c through equation (2)?

Comments on the Quality of English Language

Minor editing of English language required. I'm a little confused by the presentation of lines 80-85, and would suggest a revision.
