An area earthquake defense system is disclosed which uses military
planning principles; automated command and control systems; the
technology of wave manipulation demonstrated in optical engineering,
sonar, and anti-tank weapons and their countermeasures; and proven
electromagnetic technology. Deeply buried, specially configured, passive
devices attenuate, temporally segment, and redirect earthquake shock
waves. Such a system, fully integrated into the local geological
structure, can reduce the shock reaching the protected area, and, within
that area, channel it away from those structures most difficult to
protect with single point measures. This is especially true when the
plurality of passive devices is complemented by an automated decision and
command loop and dynamically reconfigurable active devices embedded at a
variety of depths. Further, within the defended areas those structures
enhanced with electro-magnetic levitation systems can be raised from
their bases and, by partial or full decoupling, isolated from the shock.
Structures with electromagnetic motion control systems can further be
protected by having a means for controlling their displacements during
the earthquake and for restoring them to their original location on the
site despite any lateral translations experienced during the event.
