The volcano was named Mt. Cleveland in 1894 by a group of United States scientists after they studied the area. It was named after the President of the United States at that time...Grover Cleveland.
Chuginadak is an uninhabited island, so there is not any danger to human life on the island since nobody lives there. The main safety concern with the Mt. Cleveland volcano is for airplanes flying above it.
An important danger of an eruption of Mt. Cleveland is the ash plume that rises high into the atmosphere. The ash has gone up to nearly 40,000 feet in the air. The ash can damage the outside of an airplane. It can also be pulled into the jet engine which can cause the engine to fail.
