Fig. \ref{992144} presents the damage propagation of the masonry prototype undergoing an accelerogram, without and with isolation. Through a 3D nonlinear time-history analysis, it can be affirmed that the isolated masonry is safe in terms of inter-story drift. The isolated structure is subjected to seven accelerograms according to Indonesian code, with the target location is Timika city, Papua island (0.6g of PGA). The FE model allows the application of two horizontal components of the earthquakes. A moderate damage is present, but only 0.28% as the average of maximum drifts, an outcome which assures the suitability of a low cost isolation. Also, the isolator deformation satisfies the limit of critical deformation. The average value obtained (111 mm) is smaller than the critical shear deformation, which is 300% of total rubber thickness (or 150 mm). This critical value is found through experimental researches \cite{van2012horizontal}\cite{de2011stability}. It indicates that the isolation system is capable of surviving the selected ground motions.
