New island born in the Red Sea at the Zubair archipelago (Jemen)

NASA satellite images show that the eruption in the Red Sea in the Zubair archipelago has produced a new island. The island is circular, about 500 m wide and located about 1 km north of Rugged Island. It consists of fresh probably basaltic lava flows and an active vent seems to be in its center.
A large steam plume, generated by evaporating sea water at the entry of lava flows into the sea is seen on the satellite image, drifting north.
The island has apparently passed through an explosive Surtseyan phase very quickly, probably because the erupting basalt lava was poor in gas and because the output rate was high, so that the vent could be sealed from water access in short time.

Eventually, after a long repose interval, the volcanoes of the island became active again. One of the largest eruptions generated hot ash flow that engulfed once verdant mountain forests and buried them under many meters of hot ash. ... [more]
