This report details the effect of shock-induced conductivity on the operation of the Kratz velocity gauge, which measures the ground particle velocity induced by the shock wave due to a large-yield high-explosive or underground nuclear detonation. Such shock waves are typically strong enough to induce significant ground conductivity, which can affect the operation of the gauge. Three models of increasing fidelity to the physics of the advancing conductivity front are presented and analyzed. Numerical results indicate that, for typical gauge parameter values, shock-induced ground conductivities of 100 mhosm or less do not affect gauge response.
