Map of the June 27th lava flow as of 26 Jan (USGS / HVO)
Thursday, Jan 29, 2015
The June 27th lava flow remains active, but its advance is slow. The leading edge is currently stalled roughly 500 meters from Highway 130 at Pahoa. Breakouts remain active a short distance upslope of the leading tip of the flow, and continue to slowly widen the flow. [more]

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. [more]

Friday, Jan 16, 2015
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. ... [more]

Forcasted volcanic ash plume from the Hunga Haapai volcanic eruption (VAAC Wellington)
Monday, Jan 12, 2015
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. ... [more]
Wednesday, Jan 07, 2015
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. ... [more]
Map showing the location of the lava flow near Pahoa as of 6 Jan 2015 (HVO/USGS)
The June 27th lava flow front has stayed at approx. 1 km distance (approx. 1 km) from Pahoa, but the flow itself remains active and continues to expand laterally with several breakouts: ... [more]
