Hunga Tonga-Hunga Ha'apai volcano news & activity updates:

Thu, 29 Jan 2015, 08:58
An exceptional satellite image taken by the European Pléiades satellite from 19 January shows the new island that formed during the eruption near Hunga Ha’apai island (left in images) earlier this month and joined it by forming a new peninsula, composed of a broad, flat ash cone with a water-filled crater. The image also shows that activity seems to have already stopped by 19 Jan when the image was taken. Most likely, the new land addition will be eroded within months, because it seems mainly to be composed of loose materials, as opposed to more resistant solid lava flows.

Forcasted volcanic ash plume from the Hunga Haapai volcanic eruption (VAAC Wellington)
The submarine eruption has apparently breached the surface. A steam and possibly ash plume was reported to have reached up to 30,000 ft (10 km) above sea level today and yesterday, New Zealand's VAAC Wellington reported, based on pilots' observations. ...plus

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. ...plus [lire toutes]
