just the question about lab 3 worksheet 2 thanks
QUESTIONS 1. If both grams in Fi which seis e, but at different recorded the same am station (A or B) was farther away from the epicenter? Why? 2. If seismograms in Figure 10 are from the same station, but recorded two different earthquakes, which earthquake (A or B) released more energy? Why? USE YOUR WORK ON FIGURE 15 To ANSwER THE FOL 3. what direction does the NM-1 line follow? Use the compass rose on Figure 15 to find Hint: the direction. This direction is called the strike of NM-1. 4. What is the strike (direction) of the NM-2 line? Again, use the compass rose. 5. Using the scale on Figure 15, approximately how close does the NM-1 line come to Memphis (station MET)? Remember to record units of length 0km or miles) you use. 6. Looking at the seismograph stations nearby, is Memphis (MET) in an area of compression or dilation? to be the 7. Using Figur 4, NM-1 a right lateral or lateral fault? Hint: NM-1 left lateral fault plane and determine if the of compression and dilation match a right or areas fault.Explanation / Answer
1. The station B is farther than station A as the difference in the arrival of S wave and P wave is more in station B seismogram.
2. The amplitude of both P wave and S wave will decide (as it were in use in early days body wave magnitude and surface wave magnitude scale) . thus the Earthquake B has more energy than A.
3. The strike direction of NM-1 is N90E
4. The strike direction of NM-2 is N90E.
5. It is about 17-18 Km from the MET station.
6.MET is lying in an area of compression because the first arrival phase of P wave is in upper or positive direction.
7. It is left lateral as the MET and EBZ are compressional whereas PGM is dilatation in nature.
