Answer 3

For 2. http://www.colorado.edu/physics/phys2900/homepages/Marianne.Hogan/waves.html & http://allshookup.org/quakes/wavetype.htm


This should help with 3.
http://www.geo.mtu.edu/UPSeis/locating.html
"There are hundreds of seismic data recording stations throughout the United States and the rest of the world. In order to locate the epicenter of an earthquake, you need to estimate the time interval between the arrival of the P and S waves (the S-P interval) on the seismograms from at least three different stations."
