How to respond to unanticipated earthquakes has become a concern in Japan after the 2011 off the Pacific coast of Tohoku Earthquake. Seismic design standards for railway facilities therefore need to assume that earthquakes on an unanticipated scale may occur, and should be able to prevent such events causing catastrophic damage. This concept is called "anti-catastrophe." Thus, in addition to conventional "improvement of seismic performance," it is necessary to improve "anti-catastrophe" performance to minimize damage from huge earthquakes. This paper introduces some techniques to improve anti-catastrophe performance.
