The energy distribution of larger shocks of an earthquake group is an important characteristic specifying the group, but it cannot be sufficiently expressed by the widely used coefficient 6 of Gutenberg-Richter formula. In order to characterize earthquake groups, a kind of index, relative entropy, R, for energy distribution of larger shocks belonging to the group, was introduced. This index R is effective for characterizing quantitatively the type of earthquake groups, ranging from main-shock type to swarm type.
