Data
This work is supported by the UK’s Natural Environment Research Council
(NERC) through the CATFAIL project NE/R001693/1 ‘Catastrophic failure:
what controls precursory localization in rocks?’ We acknowledge the
beamline PSICHE at SOLEIL for provision of synchrotron radiation
facilities (standard proposal 20160434) and thank our reviewers Jess
McBeck and Phil Benson for their thoughtful reviews and suggestions. We
would also like to thank the University of Edinburgh Geosciences
Workshop for their support in developing the experimental apparatus, and
Andy Bell for useful discussions about modelling the correlation length
evolution. We declare no conflict of interest. The data supporting our
conclusions can be found in main text, the Supporting Information and in
