20090312950 | METHOD AND SYSTEM FOR REDUCING THE LOSS CAUSED BY AN EARTHQUAKE - Catastrophic earthquakes cause tremendous loss to people, especially when they occur unprepared. Imminent prediction of the earthquake with occurrence time, location and magnitude may give people time to prepare for it and minimize the loss.

This invention discloses a method and system that work around the difficulty of the imminent prediction of the earthquake. Instead of trying to predict the occurrence, it triggers the earthquake artificially at a known time so that evacuation and other preparations can be accomplished prior to the triggering time of the earthquake to reduce the loss caused by the earthquake. The artificial triggering of the earthquakes may be implemented by at least one underground nuclear explosion. | 12-17-2009 |

It is first assumed that said first shear slip is the only one that is not stable according the Mohr-Coulomb slip criterion applied to contemplated fault planes with all conceivable orientations and calculating according to the Mohr-Coulomb slip criterion the principal stress directions as a function of the friction coefficient f. After that, it is established according to the Mohr-Coulomb slip criterion a relationship between two of the principal stresses. Moreover the normal stress σv in a known direction Sv is determined and, according to the elasticity theory, a relationship between the normal stress σv and the principal stresses is established. Then expressions of the three principal stresses as a function of a scalar parameter is established, and a function of the elastic deformation energy per unit of volume relative to an isotropic reference stress state with the pressure σv based on the expressions of the principal stresses is established. Finally, the remaining degree of freedom is eliminated by determining the value of said scalar parameter which minimises the function of the elastic deformation energy and the value of the scalar parameter in the expressions of the principal stresses is inserted. | 03-11-2010 |
