CEE 431 Problem Set 6 Winter 2006 (Due: Wednesday, March 1, 5:00 pm) Consider the 200-km long, strike-slip fault shown below. The distance from the site to the nearest point on the fault is 30 km. In solving this problem, make the following assumptions: The maximum earthquake magnitude to consider can be estimated assuming that the full length of the fault ruptures during and earthquake. Use the strike-slip equation from Table 4-1 Earthquakes with magnitudes below 4.0 can be ignored. The seismicity of the site is described by log λ m = 4.1-0.7M Use the Cambell (1981) attenuation relationship. Divide the fault length into 8 seqments of equal length Divide the magnitudes into 8 ranges of equal change in magnitude Problem 1. Compute the probability that the earthquake will be located within each segment, the

Compare these approximate values with the exact solution, given by the integral of Eq. 4.4. The closed form of this integral is given in the solution Problem Set 5. . Problem 2 . Compute and plot the likelihood of each of the 8 ranges of earthquake magnitude. Problem 3 . Compute the annual rate of exceedance of a PHA of 0.15g at the site. Problem 4. What is likelihood that this level of acceleration will be exceeded at least once during the next 50 years? (YOU ARE FREE TO WORK IN GROUPS OF TWO ON THIS ASSIGNMENT) 200 km Site 30 km...
