Steam plume from Nishinoshima on 27 Nov 2014 (Landsat 8 image / NASA Earth Observatory)
The eruption continues and has been going for more than a year now. It has enlarged the island to 1.89 square km (0.73 square miles). The highest point is now approx. 100 m above sea level.
Comparison of Nishinoshima from shortly after the birth of the new island (image 21 Nov 2013, lt), the merging with the old island (25 Dec, rt), formation of extensive lava deltas (7 April 2014, lb), and the disappearance of the old island under new lava (13 Nov 2014, rb) (Source. Asahi.com)

Landsat 8 satellite image showing the Nishino-shima island on 8 Oct; white lines=contour of old island now covered by fresh lava flows (annotation: Culture Volcan)
The volcanic eruption on the remote island continues. A recent satellite image that the lava flows from the active vent(s) have now covered the older part of the island, the original tiny Nishino-Shima island. ...more

Comparision of satellite images from 21 Aug and 6 Sep, showing the active lava flows (images: GSI/AIST, annotations: Culture Volcan)
Lava flows continue to be active and enlarge the growing island. During the past weeks, these have contributed to the growth of a platform towards the north of the active vents.

View of the Nishino-Shima island from the west on 26 Aug (Japanese Coast Guard)
The island remains active and continues to grow as lava flows add new land to it. The Japanese Coast Guard made another survey flight on 26 August and observed ongoing effusive and explosive activity in the main crater. ...more

Nishinoshima on 23 July (image: Japanese Coast Guard)
Activity at the growing island continues, perhaps even with increased intensity, judging from the recent pictures obtained by the Japanese Coast Guard on 23 July: ...more

Landsat 8 images of Nishino-Shima on 2 June and 4 July, showing the new platform to the east (images: AIST, annotation: Culture Volcan)
The currently fastest growing island of the world remains active, with both effusive (lava flows enlarging the island) and explosive activity (strombolian and phreatomagmatic = water-magma explosions). ...more

An explosive event occurred last night at the growing island volcano. VAAC Tokyo reported an ash plume at 10,000 ft (3 km) altitude drifting to the northeast.

3 vents at Nishinoshima volcano (13 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. ...more

Nishino-shima on 21 May 2014 (Japanese Coast Guard)
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. ...more

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).
