Dear authors,

Thank you for the revision of your manuscript 'The effect of effective rock viscosity on 2D magmatic porosity waves'. I have now read the manuscript and the replies to the reviews and in my opinion all concerns have been satisfactorily addressed. I am therefore pleased to accept your manuscript for publication in Solid Earth. When uploading your final files, i do ask that you please use that opportunity for the following technical corrections:

1. Line 52, '... may result in different 3D shapes': please add shapes of what phenomenon (channels?)

2. Please add labels a), b) etc to Figures 2, 5, 6 and 7

3. Non-dimensional parameters are indicated with a prime '. Are viscosities in equations 22-25 non-dimensional or dimensional?

4. Please add whether viscosity on the y-axis of Figure 1 is non-dimensional or not (in the latter case, please add the unit)

5. Figure 2a, please label the x and y axes

6. Figure 7, is the matrix velocity on the y-axis dimensional or non-dimensional? Does the factor 1e-4 apply only to panel b or also to panel a?

7. If the reviews were useful, you may want to consider an acknowledgement to the reviewers

Thank you for submitting your work to Solid Earth.

With best wishes,
Susanne Buiter
