Nishino-shima volcano (Japan): eruption still continuing, island grows lava delta on the SE side

The eruption on the island continues with apparently relatively steady lava effusion that feeds active flows reaching and enlarging the SE corner of the island, which has now 2.7 square kilometer of surface.
Mild strombolian activity and strong degassing occurs at the main vent, where a nice cinder cone has grown. The lava mostly flows through tubes, where it is hidden, to reach the active lava delta on the SE tip of the island. A smaller part seems also to feed/inflate inland surface lava flows in an area NE of the cone.
