Destructive earthquakes may happen anytime anywhere at. Many lives and property were lost, and public traffic and life-lines suffered from damages in the past seismic events. Seismic isolation technology has gained popularity in the recent decade as one of the measures for seismic protection of structures, and elastomeric isolators are the essential devices which construct seismic isolation systems. In this paper, principle of seismic isolation, actual records obtained in seismic-isolated structures, characteristics and requirements of isolators, basic issues of rubber materials and aging properties, and recent activity regarding development of ISO standards are introduced.
