The Big One will be a great earthquake. An earthquake is the shaking of the ground cause by seismic waves. Almost all earthquakes occur when pent up stress in rocks along large, active faults (like the SAF) is suddenly released as the rock breaks.he Big One will be a great earthquake.

  Magnetism is the force generated by any moving charged particle or charged particles. A magnetic field is the result of the motion of a charged particle or charged particles, and this field is generated in no other way. Any time a charged particle moves, it creates a magnetic field around its path of travel.
The 'poles' of the molecule tend to line up parallel with the field and reinforce it. Such molecules, with permanent magnetic moments are called paramagnetic. Although paramagnetic substances like oxygen, tin, aluminium and copper sulphate are attracted to a magnet the effect is almost as feeble as diamagnetism.he 'poles' of the molecule tend to line up parallel with the field and reinforce it.
