Comment on the “Ground Water Chemistry Changes before Major Earthquakes and Possible Effects on Animals”, by R. A. Grant, T. Halliday, W. P. Balderer, F. Leuenberger, M. Newcomer, G. Cyr and F. T. Freund. Int. J. Environ. Res. Public Health, 2011, 8, 1936–1956
Here, we suggest that electromagnetic emissions before rupture may be the mechanism for the explanation of abnormal behavior of animals before earthquakes.
