Correction to: Nature Communications https://doi.org/10.1038/ncomms14914, published online 11 April 2017.

The original version of this Article omitted a reference to previous work in ‘Hobbs, L.K., Gilbert, J.S., Lane, S.J. & Loughlin. S.C. Supplementary Case Study 3: Interactions of volcanic airfall and glaciers. In Global Volcanic Hazards and Risk’ (eds Loughlin, S.C., Sparks, S., Brown, S.K., Jenkins, S.F. & Vye-Brown, C.) 223–232 (Cambridge Univ. Press, 2015). This has been added as reference 71 at page 11 in the discussion: ‘The northern AP is defined as having a ‘moderate to extremely high likelihood of supraglacial airfall by active volcanoes’’. This has been corrected in the PDF and HTML versions of the Article.
