The eruption at Nabro volcano is continuing. The explosive phase seems to have ended, but there is still a large white steam and gas plume coming from the volcano and a large hot spot is visibe on the MODIS/Terra satellite images. Most likely, large lava flows are still being erupted. ...more

The eruption of Puyehue Cordon-Caulle has decreased in intensity, although near continuous ash emissions are still going on. In its latest bulletin on Friday, SERNAGEOMIN reports the height of the ash column did not exceed 3 km, and the plume is drifting at flight level 200 (20,000 ft / ca. 6 km) altitude into Argentina, where the ash fall has become a major problem in several towns and villages near the border, in particular in and around Bariloche. Electricity and water supply have become damaged, impacting the tourist industry severely. As well, faramin, especially of sheep, is suffering heavy losses.

The eruption at Puyehue-Cordón Caulle continues to be big. In its latest bulletin, SERNAGEOMIN reports that a dense pulsating column of ash is erupted and reaches up to 9 km altitude, corresponding to strongly fluctuating levels of tremor. At night, the lower 1.5-2 km of the column show incandescence. The eruption column produces a visible plume of 250 km length to the SE where heavy ashfall occurs. Further apart, in Argentinia and across the globe in Australia and New Zealand, the ash plume which is now circling around the southern hemisphere continues to cause serious disruption of air traffic.

The eruption at Puyehue-Cordón Caulle is still going strong, producing a pulsating 4-8 km high column of ash and incandescent material visible at night at the base of the eruption column. The Volcanism Blog has posted a great summary of the latest two reports of SERNAGEOMIN from 11 and 12 June. The key points are: ...more [read all]

The eruption plume from the ongoing eruption at Nabro volcano is driffting at an altitude of ca. 7km (20,000 ft, flight level 200) and has reached southern Egypt. It is well visible on satellite images.
The eruption at Puyehue volcano shows no signs of exhaustion. While the plume had decreased significantly after the initial eruptions, the eruption has increased again in the past days and the volcano is now producing a near-constant ash column which reaching 4 to up to 10 km altitude and drifting east (VAAC Buenos Aires). ...more
Higher-resolution satellite images show that the vent of the new eruption in Eritrea is not from Dubbi, but its heighbor Nabro volcano. This is the first historical eruption of Nabro.

Following a swarm of intense earthquakes, a new and apparently large explosive eruption started last night in Eritrea near the Ethiopian border, in an area which is the continuation of the spreading rift axis of the Red Sea. ...more [read all]

The eruption at Puyahue volcano has weakened a lot in the past days. As of today, 10 June, the volcano continues to erupt, but the ash cloud reaches "only" 15,000 ft (ca. 5 km) altitude, compared to >10 km in the previous days. (VAAC Buenos Aires)
