Detection of variations in the relative velocities of the primary and secondary seismic waves – expressed as Vp/Vs – as they passed through a certain zone was the basis for predicting the 1973 Blue Mountain Lake (NY) and 1974 Riverside (CA) quake.  Although these predictions were informal and even trivial, their apparent success was seen as confirmation of both dilatancy and the existence of a preparatory process, leading to what were subsequently called "wildly over-optimistic statements"  that successful earthquake prediction "appears to be on the verge of practical reality." 
Have you ever asked yourself, what it intelligence? Intelligence can be described as the ability to have skills, necessary to face the requirements and challenges, which man is daily confronted with.
According to the Websters Dictionary, intelligence is a capacity to perceive and comprehend meaning, information, news.
Nowadays a new, more complex and extensive conception of intelligence has been developed, and the determination can be simply expressed as: Intelligence is a skill to solve complex problems in the changing circumstances.
One cannot say, that IQ = Intelligence, because not all the aspects of the intelligence can be reliably measured. Intelligence can have different forms, co-existing with each other, and not all of them are easily measurable. Besides, sometimes it is difficult to place certain expressions of intelligence (like intuition) into one or another category.
