Claim:
1. A system for preventing damage from an earthquake to an object, having a foundation anchored to a ground surface, which is generally horizontally oriented as defined relative to a gravitationally defined vertical direction, the system comprising: means for guiding mounted on the foundation and on the object for allowing relative displacement between the object and the foundation in at least one horizontal direction; at least one actuator is capable of displacing the object in the at least one horizontal direction relative to the foundation as allowed by the means for guiding; a central processing unit, where the at least one actuator is communicated with the central processing unit; and at least one displacement sensor, where the central processing unit is communicated with the at least one displacement sensor, where the at least one displacement sensor is capable of detecting a displacement of the foundation in real time and/or the ground surface and/or the object and capable of inputting displacement data in real time to the central processing unit, and where the central processing unit is programmed to activate the actuator in real time in dependence on the displacement data so that the object is displaced relative to the foundation in real time, such that a maximum horizontal displacement vector of the object is kept substantially smaller than a horizontal maximum displacement vector of the foundation.
