ABSTRACT:
An earthquake disaster prevention system having: an estimation section to estimate a size of an earthquake from a P-wave of the earthquake detected by the earthquake detector; a stopping control section to control to stop the motion of the operation device when the size of the earthquake estimated by the estimation section exceeds a stopping reference value; a calculation section to calculate at any time the size of the earthquake from the S-wave of the earthquake detected by the earthquake detector; a convergence judgment section to judge convergence of the earthquake by judging whether a predetermined earthquake convergence condition is satisfied from the size of the earthquake calculated by the calculation section; and a resumption control section to resume a predetermined motion of the operation device stopped by the stopping control section when the earthquake is judged to have converged by the convergence judgment section.
