The Japan Coast Guard says the latest volcanic eruption on a remote island in the Pacific Ocean is continuing.
Nishinoshima had a minor eruption, its first since last August, on July 12th. The uninhabited volcanic island is about 1,000 kilometers south of Tokyo.
Coast guard officials conducted an aerial survey on Wednesday and spotted a 600-meter-long lava flow from a new crater on the island's eastern slope.
The officials also saw smoke rising about 200 meters high and volcanic gas spewing continuously.
Tokyo Institute of Technology Professor Kenji Nogami, who took part in the survey, says magma may be rising close to the surface and volcanic activity has restarted.
He expects the volcano to keep spewing lava for some time.
From 2013, Nishinoshima had active eruptions for about 2 years.
The Meteorological Agency has issued a warning for flying rocks and lava flows within a 1.5-kilometer radius from the crater.
