3 vents at Nishinoshima volcano (13 June)
Steam plume from Nishinoshima on 13 June
A small lava lake (?) in the smaller vent at the eastern foot of the cinder cone (11 June)
Eruptions continue to add land to the remote island volcano. Recent pictures by the Japanese Coast guard on 11 and 13 June show steaming along the shoreline, indicating active lava flow fronts, possibly tube-fed since no surface incandescence was visible.
Nishinoshima on 11 June
A large steam plume mixed with bluish gas and light brown ash was rising from at least 3 vents, two of which belong to the large central cinder cone, while the other smaller vent to the east of the base of the cone emitted most of the bluish gas (SO2) and seems to host a small lava lake feeding an active flow.
Pulsating strombolian eruptions ejecting tephra and brown ash plumes were seen from the central cinder cone.

The eruption on the remote island continues. The most recent overflight pictures by the Japanese Coast Guard show two active vents, one with a small lava-filled vent likely producing strombolian explosions, the other emitting a steam and gas plume. Lees alle

A possible explosive eruption occurred this morning; VAAC detected an ash plume at estimated 7,000 ft (2.1 km) altitude drifting east from the volcano. This could have been caused by a stronger phreato-magmatic explosion (sea water coming in contact with magma). ... Lees alle

The ongoing eruption continues to add new land to the island with what seems a relatively steady effusion of lava flows. A new overflight by the Japanese Coast Guard shows that at least the second vent that appeared in late January is still active, feeding lava flows that continue to spread and currently have active fronts all along the eastern coast. ...

The island continues to grow as lava flows slowly spread into several directions. This is shown nicely by the latest aerial survey pictures the Japanese Coast guard took on 28 Feb. The most active flow fronts are currently at the southern shore while advance on the northern and eastern margins of the flow field has slowed down. ... Lees alle

The island continues to grow by progressing lava flows into several directions, as the latest images by the Japanese Coast Guard from 16 Feb show. Its highest peak, formed by the western of the 2 active vents, was measured at 66 m, i.e. it now reached almost twice the height of the peak of the old island. The new addition has more than doubled the size of the island so far. Lees alle
