Correction to: Nature Geoscience https://doi.org/10.1038/s41561-018-0144-2, published online 4 June 2018.

In the version of this Article originally published, the ‘Data availability’ section contained an incorrect DOI for data from the FLATS (XV) seismic network (https://doi.org/10.7914/SN/ZE_2015); the correct DOI is: https://doi.org/10.7914/SN/XV_2014. This has now been corrected in the online versions.
