EBISA (Equipment Base Isolation System Analysis) code evaluates the effectiveness of seismic isolation for the important components in the seismic safety, and consists of the three codes, probabilistic seismic hazard code (SHEAT), seismic dynamic response analysis code (RESP) and seismic failure probability and frequency evaluation code. In these codes, RESP code is used for the calculation of the dynamic response behavior of a nuclear component with seismic isolation devices. This report describes the overall explanation of EBISA, and user's guide of RESP code including the analysis function, input manual and sample problem.

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.
