Dear Junnan Xiong,

I have read with interest your manuscript and I"m pleased to see the effort you have taken to include earlier comments. However, I think the manuscript can improve when you consider the below comments.

Best regards,
Albert.

• Reword running title to be more specific. For example reword to ‘Landslide risk zonation for areas containing hydrocarbon transport pipelines’.
• Line 35&36. Change the word ‘mileage’ to ‘length’. Mileage has implicitly the meaning of a none SI unit ‘mile’.
• Line 119 – 121. ‘The irrational unit …..’. Explain what ‘the irrational unit’ is.
• Line 122. Reword ‘The object of the pipeline vulnerability assessment in the landslide area was the pipeline’ to something like: ‘This study focusses on assessing the vulnerability of transport pipelines to landslides’.
• Line 131. Remove ‘…of the paper…’
• Line 147-148. Replace ‘The neural network, an ….. and an output layer.’ with ‘A neural network is a nonlinear mathematical structure which is capable of representing complex nonlinear processes that relate the inputs and outputs of any system (Hsu et al., 1995).’
• Line 151-152. Replace ‘…and is good at dealing with a lot of uncertainty information.’ With ‘…and can incorporate well uncertainty information.’
• Line 155-157. Reword the sentence ‘This method can be … these fuzzy information.’ I’m unsure what you try to say here.
• Line 183-184. Double check your interval and reword such that it reads something like: ‘Besides, the susceptibility degree in the area was monotone decreasing in the slope interval of 60 to 90 degrees.’ So do you mean the slope interval of 60 to 90 degrees?
• Line 184. Change ‘…in a slope at ….’ To ‘…in slopes at…’.
• Line 190-193. Reword ‘Each 200 is… by traditional methods.’ It is unclear what you mean here.
• Line 204. Reword ‘…indicator, and the more difference of the data, the…’ to something like ‘…indicator, the more difference the data, the…’.
• Line 258. Reword ‘…and make the micro results macro.’ To something like ‘…and accelerate findings’.
• Line 261. Remove ‘degrees’ such that it reads: ‘The susceptibility and vulnerability degrees were distinguished ….’.
• Line 332. Remove ‘with’ such that it reads: ‘…and planners a comprehensive…’.
• Line 333. Change such that it reads: ‘…of landslide risk in areas containing pipelines.’.
• Line 334. Remove ‘… or even pipelines in an area….. by landslides.’ Such that it reads: ‘… of failure of slopes.’
• Line 340. Reword such that it reads: ‘…of different methods and recommend one or more optimal approaches.’.
• Line 342-345. Reword to something like: ‘This study shows that landslide risk assessments can be performed with minimal amount of relatively easy to obtain datasets. We advocate to establish a database with assessment parameters similar as described by this study to construct dynamic landslide risk assessment models.’
