Two earthquakes have occurred recently on the fault shown on Figure I below. Earthquake A, magnitude 5.0, happened two days ago Earthquake B, magnitude 3.0, happened yesterday, Approximately how much more energy was released during earthquake A than during earthquake B? What were the depths of focus of each earthquake? Earthquake A depth _miles Earthquake B depth miles Although earthquakes A and B had different magnitudes, their Mercalli Intensity ratings were identical, V. Describe the effect of these two earthquakes (according to Mercalli Scale). Provide a hypothesis to explain why these earthquakes had similar Mercalli effects, but very different magnitudes fault scarp B 147 74 -5 depth (miles) Figure I 10. Review Figure I, one geologist thinks that earthquake B is an aftershock of earthquake A, but another geologist disagrees. Which geologist is right? Explain your answer.
