RB Fuller's tetrahedron structures and the octet truss are perfect for this function, the stresses will be carried by the whole structure and thereby minimized, just isolate the foundation from the earth and build a geodesic dome over it.<br><b>References : </b><br> Triangles are best, bar none… RB Fuller’s tetrahedron structures and the octet truss are perfect for this function, the stresses will be carried by the whole structure and thereby minimized, just isolate the foundation from the earth and build a geodesic dome over it.

However, the energy imparted to a building during an earthquake has to be dissipated somehow, and a stiff, rigid building actually has to be built stronger than one that can bend, which increases cost and limits the height of such a building. Therefore, a less stiff building is actually more desirable, since it will also resist earthquakes, but provides a taller building for the same cost or materials.<br><b>References : </b><br> Triangular structures are "stiff," i.e., they resist bending.
