Given the earthquake data below, complete the following tasks. (a) Use the semi-log paper provided (next page) to plot the Gutenberg-Richter recurrence curve and then estimate the parameters for this region. (b) What is the return period for a 6.5 earthquake? (c) The seismic parameter B, for this region has been established as 0.45. What is the value of the seismic parameter C, if the data was collected over the period of 150 years? Assume that the value is estimated by considering magnitudes between 4 and 5 , only. (d) What is the probability (\%) that an earthquake of magnitude 3 will occur in a given year
