Nishinoshima seen on 25 Dec 2014 (Japanese Coast Guard)
The eruption continues well into its second year, steadily enlarging the island with lava flows. During the past weeks, most activity has been concentrated to produce flows towards the north and northwest where the island has been growing considerably. ...plus [lire toutes]

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)

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. ...plus [lire toutes]
