The Japan Coast Guard (JCG) reported that during an overflight of Nishinoshima conducted from 1335 to 1412 on 17 January surveyors observed continuous gray emissions rising from the central crater of the pyroclastic cone to 1.8 km (5,900 ft) a.s.l.
and drifting E and NE.
The central crater was open to the ENE; lava flows traveled NE and entered the ocean, producing steam plumes at the coastline.
