We showed the relation between the magnitude of induced earthquake and the reservoir storage and dam height based on the global catalog from 1967 to 1989 compiled by Ding Yuanzhang (1989). By multiplying reservoir storage with dam height, we introduced a new parameter named EE. We found that the cases with specific EE and magnitude do not exceed a limit. Based on the discussion of its physics, we called EE the equivalent energy. We considered this limit as the upper limit of magnitude for reservoir-induced earthquakes. The result was proved by the recent cases occurring in China. This size limitation can be used as a helpful consideration for reservoir design.
