Abstract
Method and apparatus for preventing collapse of a structure due to an earthquake by using a construction with a water chamber whose outside contacts a receiving area, provided to the earth's surface, and balance cables each connected to a plurality of weights and variable weights lighter than a predetermined weight. The water chamber is separated from the receiving area and raised form the earth's surface by draining off the water in the water chamber during an earthquake, and returns to its original position by increasing the weight of the water chamber once the earthquake completely stops.

An apparatus for preventing collapse of a structure due to an earthquake, comprising:
- a receiving area provided to the earth's surface where a structure is to be built;
- a plurality of balancing chambers equidistantly provided on all sides of the receiving area;
- a water chamber built under the structure and having an outside closely contacting the receiving area;
- a balance weight provided to the bottom of the water chamber and serving as a center of gravity;
- sand provided around the balance weight to distribute vibrations;
- and
- an earthquake-proof means installed on the upper part of the water chamber in order to prevent seismic waves from being delivered to the structure through balance cables.
