Map of the June 27th lava flow as of 26 Jan (USGS / HVO)
Kilauea (Hawai'i): 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.
Hunga Tonga-Hunga Ha'apai (Tonga, Tonga Islands): (29 Jan) 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.

Bardarbunga (Central Iceland): The visible intensity of the eruption continues to decrease gradually. The Icelandic Met office conducted air-borne measurements of the lava field last week, showing that it has significantly thickened (rather than expanded laterally) during the past weeks, and is now estimated to contain approx. 1.4 cubic kilometers of lava. Effusion rates, although decreasing, are still close to an impressive 100 m³ per second. ... [mehr]

Bardarbunga (Central Iceland): No significant changes in seismic and volcanic activity have occurred recently at the ongoing Holuhraun eruption, but overall, a slowly decreasing trend of the activity is becoming evident. Still, magma effusion remains quite impressive, especially the large lava lake inside Baugur crater on the main part of the fissure. ... [mehr]
