Nishino-shima volcano (Japan) eruption update: island continues to grow

The youngest island of the world continues to grow as the eruption continues. Recent footage shows (from 24 Nov) shows strombolian activity and a lava flow on the southeast flank of the small new cone.
The strombolian activity often ejects glowing bombs that land in the sea water and create spray and leave short-lived areas of boiling water around them. The longer the eruption continues in this so-called magmatic style (the vent being isolated from sea water, allowing the formation of welded scoria and lava flows), the greater the chances are that the island will survive wave erosion once the eruption stops.
The change in eruptive style (from explosive magma-water interaction, so-called surtseyan, towards dry, magma-only driven eruptions occurred between 22-23 November.
