Structural change in a network of disaster preparedness relations is assessed using a staged two-point repeated measures survey. An earthquake scenario simulates a sudden and dramatic jolt to the network. Measures of horizontal and vertical differentiation are found to be sensitive to structural change in the network. We conclude that disaster theory of interorganizational relations is advanced by using network analysis to specify and test hypotheses about different types of change.
