Nishino-shima volcano (Japan): eruption continues, approaches 2 year anniversary

Explosion from Nishinoshima's active main vent on 17 Nov (Japan Coast Guard)

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.
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.
