Geology Midterm 1 crust mantle outer core inner core 2 S waves cannot travel through the core 3 There is a close relation between earthquakes and movement 4 A 1 C 2 The motion of plates is driven by weight of cold slabs 3 Tectonic plates are composed of the crust and upper most mantle 4 On Feb 20 1835 during the Beagle expedition Charles Darwin witnessed the devastation of a great earthquake of magnitude probably in 8 5 to 9 Which recent earthquake is possibly a repeat of that event Chile 5 Which denotes the widely accepted mechanism that generates earthquakes Elastic 6 Which of these locations experienced three major earthquakes during the winter of 1811 1812 New madrid 7 Chile was the largest earthquake 8 Fires 9 Which did not occur during the 1755 Lisbon earthquake Buildings sinking 10 11 all columns fell in the same direction Who was the first person to describe the mechanism that generates earthquakes after studying which earthquake REID 12 13 In what location would you expect the largest earthquake COME BACK C What is represented by the horizontal line along the intersection of the plane and the water strike of the surface 14 15 What type of fault is shown in this figure reverse dip slip fault In what tectonic environment do you expect this kind of fault to form Transform boundary Paris France GPS is used in earthquake prediction to all of the above Point A where slip initiated during the earthquake is called the focus Which info is not used to calculate the Richter magnitude of an 16 17 18 19 earthquake the amount of destruction 20 An EQ measuring 7 on the Richter scale releases about 10 time more energy than an EQ of magnitude 6 21 If a magnitude 9 0 event is expected along the Alaska Aleutan volcanic arc every 150 years how often is a magnitude of 8 0 expected 15 22 Why is the southern San Andreas fault near LA considered a candidate for a major earthquake A 23 Six large historical earthquakes occurred on the Parkfield segment of the San Andreas fault prior to 2004 with the last one of these occurring in 1966 The graph below plots the actual versus predicted dates of all the earthquakes on the Parkfield segment and shows EARLIER What ground material is most stable in EQ s bedrock Wood frame is the strongest The 1988 Armenia EQ had a modest magnitude of 6 9 yet it resulted in an estimated 25 000 deaths Why buildings were poorly constructed Modified Mercalli map Florida wasn t felt Alaska has the greatest seismic hazard California Shake out CA C PAGER estimate of fatalities Which of the following statement concerning the 2011 Virginia EQ is true 24 25 26 27 28 29 30 31 32 33 Constant seismic zone in Virginia 34 Which was the largest East Coast EQ Charleston What was observed during the 1811 1812 New Madrid EQ
