Hunga Tonga-Hunga Ha'apai volcano (Tonga Islands) eruption: new island grows rapidly

A new island is now growing at the eruption site between Hunga Ha’apai and Hunga Tonga Islands. As of yesterday, it had an east-west elongated 1.5-2 km long and approx. 1 km wide shape with a half-open cone around the crater reaching almost 100 m in height already.
The new island seems already to have touched the northeastern tip of Hunga Ha’apai island. Violent sea-water and lava interaction has been generating jets of dark ash and dense steam plumes reaching several kilometers of height, as well as ground-hugging base surges.
During the past days, ash plumes have remained confined to lower altitudes and most flights in the area have resumed.
The info graphic by Matangi Tonga online puts the submarine vent significantly to the SE of the new island, which suggests the possibility that there might been two vents - one at the shown location in the map, one at or very near the new island where the first steam plumes appeared on satellite imagery from 30 Dec shortly after the start of the eruption.
A red algae bloom observed in nearby waters of Tonga might be indirectly be related to the eruption, because the emission of volcanic particles, fluids and gasses into the sea water is known to favor their growth.

Activity continues, but seems not to have breached the surface (for now). Recent satellite imagery with clear views show a discolored water plume and a steam plume but no ash, suggesting that that the activity is still well below the surface. ... [mehr]

A new eruption is taking place in the Tonga islands in the South Sea, between the small islands of Hunga Tonga and Hunga Ha'apai, which are the tiny suaerial parts of a large underwater volcano located about 30 km SSE of Falcon Island. The last eruptions in this area were reported in 1912, 1937 and 1988. ... [mehr]
