A 1-kilometer (3,300-foot) -high column of water vapor shot up from the Pacific Ocean off a tiny Japanese island on Saturday, indicating a possible undersea volcanic eruption, a report said. The water vapor, resembling the steam emitted by a boiling kettle, was seen from the island of Iwo Jima by Japanese troops stationed there, Kyodo News agency said. The vapor was roughly 50 kilometers (30 miles) southeast of the island, and was believed to have been caused by an erupting volcano on the ocean floor, the report said, according to AP. Japan's Coast Guard planned to dispatch aircraft to the area to conduct a survey on Sunday. The Meteorological Agency said there was no danger of tsunami, potentially killer waves caused by undersea seismic activity or landslides. Iwo Jima is about 1,120 kilometers (700 miles) southeast of Tokyo.
