Abstract— We consider evaporation of the Schwarzschild black hole and note that island configurations do not provide a bounded entanglement entropy. The same remark is also valid for some other static black holes. A proposal for improving the situation is discussed.

Keywords: black holes, entanglement entropy, island configuration
