The invention relates to an earthquake protection system which is entirely immune to seismic activity. The inventive system supports buildings and other objects on virtual pendulums (Pv) configured according to the invention in the form of earthquake protection modules (56). In the case of relatively low buildings, the limit load support points of said earthquake protection modules (56) move in the manner of the oscillating end of a long pendulum with a long cycle of its own, so that the object being supported is efficiently isolated from the essentially more frequent ground vibrations. The functional behaviour of the system is not affected by the extent of the base acceleration or the frequency of the ground vibration. Even in the case of a large earthquake, the object will remain still. The system can be configured for any load and any conceivable scale of vibration. The invention describes four different examples of solutions which apply the inventive method, variants and devices derived therefrom for various applications, devices which are needed to provide support against wind force and for centring an object which is subject to wind force and has an oscillating base, and devices for isolating vertical ground oscillations.
