Questionnaire for Module 1 Geotechnical Earthquake Engineering 1) What kind of plate boundaries are studied to know the magnetic anomalies of earth? What kinds of faults exist below these plate boundaries? Why magnetic anomalies are useful in plate tectonics? 2) How does a P-wave shadow zone form on earth’s surface? How does S-wave shadow zone form on earth’s surface? Why is S-wave shadow zone much bigger than P-wave shadow zone? 3) If the epicenter of an earthquake lies on the surface trace of the fault plane, what would be dip and strike of the fault plane? What types of movements can occur along such fault during an earthquake? 4) Show the variation of shear wave velocity from crust to core of the earth, explaining the reasons for the same. 5) Explain how volcanoes are formed. 6) How do the geologists determine the age of sea floor? 7) Explain the situations that cause the formation of arcs, mountains and magnetic anomalies during earthquakes, mentioning the types of movements involved. 8) In which direction and at what velocity is the Indian plate is moving currently? 9) Explain the theory of continental drift and the evidences for it. 10) Assuming P and S wave traveled through the crust at 6 km/sec and 3 km/sec respectively, estimate the possible location of the epicenter P of a shallow earthquake if P forms an equilateral triangle with two points A (10,10) and B (35, 10) on the ground surface. What is the difference in the arrival time of P and S waves at A and B?
