Document Summary

Two classes body waves and surface waves. Surface waves are responsible for all the earthquake damage and do all the damage, they have the largest amplitude. Love waves shear waves of up/down and side to side raleigh waves rolling action. The frame is attached to the ground while a weighted spring with a pen on it makes a record on a paper. The weight doesn"t move while the frame does. The left one on the diagram measures vertical movement, while the one on the right will measure horizontal measurements. Modern seismographs use a magnet around a coil, and when the magnet moves up and down it creates a current. The p wave travels faster then the s wave. The further the earthquakes epicenter is, the greater the differ- ent in time of arrival. The surface waves will arrive after the internal waves (longer distance to travel)
