The volcano continues to erupt and is approaching its anniversary. It started with the birth of a new island offshore the old Nishino-Shima island on 23 Nov 2013, which by now has joined and completely covered and greatly enlarged the older one.
Explosion from Nishinoshima's active main vent on 17 Nov (Japan Coast Guard)
The latest survey of the Japanese Coast Guard on 17 Nov showed that although lava effusion continues at slow rate, thickening the flow field in the interior of the island, they no longer reach the shores and the island's total surface has decreased a bit due to wave erosion from 2.67 in September to now 2.63 square km.
Strombolian to vulcanian-type explosions occur from the main vent, sometimes strong enough to project bombs of meter size into the sea, i.e. to more than 1 km distance.

The eruption that had started in Nov 2013 still continues with no significant changes. During the most recent survey on 18 Oct by the Japanese Coast guard, strombolian activity was observed at the central vent, but lava flows no longer reached the coast of the young island, which is being affected and modified by wave erosion. read all

The island continues to grow with lava flows, which recently have been mostly active towards the east from the main vent, while most growth during Nov-Dec had been towards the north, where a vast plateau has been built. read all
