i need help with question 5

** 6 -6.9 Damage to well-built structure The Richter severe damage to ENERGY FROM EARTHQUAKES poorly built ones scale The amount of energy released during an earthquake Measures energy waves emitted by earthquake Buildings displaced can be approximated using the formula: 0- 1.9 Can be detected 7. 7.9 from foundations; only by seismograph cracks in the earth; underground 2-2.9 Hanging objects pipes broken may swing log10 (E) = 5.24 + 1.44M Bridges destroyed, 8- 8.9 Few structures E = energy released in Joules 3-3.9 Comparable to left standing the vibrations of a passing truck 9 and over M = magnitude on the Richter scale Near-total 4 - 4.9 May break windows, destruction, waves cause small or moving through Fiji earthanghe : magnitude = 6.2 unstable objects to fall the earth visible with naked eye intensity = 66.68 (5-5.9 Furniture moves chunks of plaster may fall from walls 3. Calculate the energy released by one of the pacific earthquakes mentioned above. Express your answer in Standard Form (to 4 significant figures) [2 marks] energy released during fiji carinquake = 1.117 x 10" Joules 4. What is the ratio of energy released by the Chilean earthquake (in 1960) compared to the earthquake you chose for question 3? [3 marks] Ratio ( chilean : Fiji earthquakes ) = 74.47:1 5. Using your calculations from questions 3 & 4, and ANY other calculations necessary, sketch a graph that depicts the relationship between the energy released by an earthquake and its magnitude on the Richter scale. * - exponential [4 marks]
