We estimated the 3-D resistivity structure around the epicenter of the 1997 Kagoshima Prefecture Northwestern Earthquake doublet in Japan by using broadband magneto-telluric (MT) data. The resistivity structure shows low-resistivity zones near the eastern and western edge of the aftershocks at depths of 5-10 km. The hypocenters of the M6 earthquakes are located near the edge of the low-resistivity zones. It is interesting that a prominent high resistivity zone is sandwiched by two low-resistivity zones at a depth of 0-3 km, and its location coincides with the distribution of the granodiorite body.
