Main comments

I find the manuscript extremely interesting. The detailed analysis of interaction between scientists and decision makers is a clear illustration of the fact that science is never neutral, and scientists must be aware of this. My main comment is that it would be useful to add some statement about the constraints that the local legal framework put on the methodological approach used for seismic hazard assessment. From an Italian perspective, where we have no earthquake insurance, the message that scientists should send to the Government and the public in my opinion must be quite conservative and deterministic. A probabilistic approach might be not very useful in terms of land planning and building safety. For instance, recurrence interval might be a misleading information in terms of Civil Protection and building codes. I am thinking at California and New Zealand. Large earthquakes are expected along the San Andreas and Alpine Faults, but in the last decades the earthquake damage has been generated by "minor" faults such as those activated in the Canterbury sequence. Therefore, without earthquake insurance seismic hazard maps and seismic zoning should be better based on maximum earthquake estimates. The state of the art and the scientific standards when dealing with disaster management should reflect the reality of the different cultural settings existing in different regions of the world. This issue was at the base of the L'Aquila trial after the 2009 earthquake in Central Italy, for instance. This is not a criticism to the manuscript. I just feel that mentioning this point will help the reader to put this really interesting scientific contribution in the proper epistemological framework.

Berryman 2012 is not in the references; maybe this is Berryman et al 2012

Short summary

This paper examines the roles of earth science information (data, knowledge, advice) in land-use decision-making in Christchurch, New Zealand, in response to the 2010–2011 Canterbury earthquake sequence. A detailed timeline of scientific activities and information provisions relative to key decision-making events is provided. We highlight the importance and challenges of the effective provision of science to decision makers in times of crisis.
