The piezomagnetic computation of magnetic anomalies due to ground loading by a man-made lake

  • P. M. Davis
Article

Summary

A method has been developed to determine the stress distribution and resultant piezomagnetic surface anomaly field due to the load imposed on the earth's crust from filling man-made lakes of variable depths and arbitrary geometries but uniform elastic properties. The dam-magnetic effect observed byDavis andStacey [1] on Talbingo reservoir in the Snowy Mountains of SE Australia is adequately explained in terms of the piezomagnetic effect if more highly magnetic rock than that measured on the surface is present at depth.
