Question

Earth sciences questions.

In the class, we discussed 1994 Northridge earthquake several times. The moment magnitude (Mw) of the earthquake was 6.7. In the following questions, we will consider two hypothetical scenarios similar Northridge earthquake in many ways, and try to see if they arc plausible. If the magnitude of this event were 8, hut the average slip, fault width, and shear modulus remain the same as in question 3, what would the along-strike length of the earthquake fault be in that case? Could it have fit within the entire state of California (note-California is around 1300 km long)? Is this scenario likely? Why or why not? If the magnitude of this event were 8, but the fault width, along-strikc length, and shear modulus remain the same as in question 3, what would the average slip on the earthquake fault be in that case? Is this scenario likely, given that the largest slip inferred in the M 9 earthquake that recently hit Japan was around 50 m? Why or why not?
