Problem 13.7

Find Poisson’s ratio for the five events in Figure 13.7a.

Solution

Poisson’s ratio can be obtained from the ratio using equation (10.2) Table 2.2a. Since , , we can get from the traveltimes and then get using equation (10,2) (see Table 2.2a), that is,

Measurements and calculations are listed in Table 13.7a.
