Thank you so much for all your help! I just took the LEED NC exam this afternoon after studying for 1 month on my own, using just the reference guide, my own notes (I’m an obsessive-compulsive note taker), and your website – no classes, workshops or sample exams – and passed! I got a 184, which I am very happy with already. Was a bit nervous because I took no sample exams nor any background in building design or construction, but in the end all the hard work paid off! Thanks again for the terrific help. Such a great feeling! =)
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."
