Eruption reported in Virunga National Park, DR Congo 31 August 2010

A report in the Irish Independent today says that there has been a volcanic eruption in Virunga National Park in the Democratic Republic of Congo. The volcano is not named, but both Nyiragongo and Nyamuragira volcanoes are situated within the park. Nyamuragira had a notable eruption at the beginning of this year.

There seems to be no other information about this possible eruption at the moment, so it’s impossible to confirm what is happening. More details here if and when we get them.

UPDATE. No further reports have emerged today about this alleged eruption. As Erik has pointed out over at Eruptions, the Virunga volcanoes are always restless so some relatively small episode of activity may be at the bottom of this isolated and unconfirmed report. So far, though, there is no sign that there has been any eruptive event of significant magnitude at either Nyiragongo or Nyamuragira. Any further news and we’ll report it here…

Watching the volcanoes in Congo 20 February 2010

Volcanic neighbours Nyiragongo and Nyamuragira in the Democratic Republic of Congo have been restless lately: Nyiragongo produced thermal anomalies (probably from lava lake activity) and a diffuse plume at the end of January, while Nyamuragira began the new year with a sizeable and dramatic eruption.

The city of Goma (estimated population 1 million) lies in the shadow of Nyiragongo. It’s the task of the Goma Volcanological Observatory to monitor these active volcanoes and keep the surrounding population and the wider world informed as to what they are up to – a task made no easier by the various problems of war, population dislocation and economic difficulty that beset this part of Africa, and by the problems in getting the money and equipment they need to do their vital work effectively.

Today IRIN, the humanitarian news and analysis service of the UN Office for the Coordination of Humanitarian Affairs, has published an article about the work of the Goma Volcanological Observatory: ‘DRC: watching the volcanoes’ (the report can also be found at Brunei.fm). The more that is known about the work of the Goma observatory, and the more support it receives, the better.

Nyamuragira from space and from the ground 23 January 2010

At the European Space Agency ‘portal’ (or, if you prefer, ‘website’) there is an interesting article about the ways in which the ESA’s Envisat has helped to monitor the Nyamuragira eruption in D. R. Congo as part of the GORISK project for using ground-based and remote sensing techniques as a tool for volcanic risk and health impact assessment for the Goma region. Dr Nicholas D’Oreye of GORISK explains the importance of the satellite contribution:

As well as helping to validate information from different datasets, the satellite images are providing invaluable information about the situation, such as the details about the lava flow and the fact that the Nyiragongo volcano is not showing any signs of abnormal activity. This has been of great importance for the local authorities and the Goma Volcano Observatory, who are holding daily crisis meetings, to reassure the local population and humanitarian agencies that Nyiragongo will be unaffected by the eruption of Nyamulagira.

Meanwhile, from ground level, the gorilla.cd blog offers a gorilla’s-eye view of the Nyamuragira eruption with some pictures of lava fountain activity taken from the Gorilla Sector of Virunga National Park.

Nyamuragira: what the satellites say 18 January 2010

Little fresh news is coming from Africa about the eruption of Nyamuragira volcano in the Democratic Republic of Congo that began two weeks ago, but satellite data indicates that the activity is continuing.

The availability of MODIS hotspot data is affected by cloud cover, which has been considerable in the area of the volcano over recent days. However, MODIS images for 13 and 15 January shows the thermal signatures of fresh lava emissions to the east and south of Nyamuragira’s summit crater.

The volcano has also been emitting considerable quantities of sulphur dioxide, as shown by OMI SO2 data. Significant SO2 clouds were detected on 13 and 17 January 2010.

Nyamuragira activity diminishes – report 12 January 2010

The latest information on the eruption of Nyamuragira volcano in the Democratic Republic of Congo comes from Samantha Newport, director of communications for Virunga National Park, who reports in a comment at the gorilla.cd blog dated 11 January 2010 that lava fountains were reaching almost 300 metres in height on Saturday 9 January, but that volcanic activity had since diminished. The decline in activity appears to be confirmed by the fact that no thermal hotspots have been detected by MODIS at Nyamuragira since 8 January 2010 (although that doesn’t mean nothing has been happening).

Nyamuragira continues to erupt 7 January 2010

MODIS hotspots at Nyamuragira volcano, D. R. Congo, 2-6 January 2010

Five days after it began the eruption of Nyamuragira volcano in the Democratic Republic of Congo is continuing, with fire fountains and very liquid and free-flowing lava. The images above, compiled from the University of Hawaii MODIS hotspots monitoring website, show the thermal signatures detected by satellite on 2, 3, 4 and 6 January 2010 (the 5 January image shows no hotspots). The flows are directed towards the south-west. The large lake is Lake Kivu, and the small body of water to its north-west is the Gulf of Kabuno. The high level of CO2 present in the Gulf of Kabuno is a potential hazard we discussed here yesterday.

The most up-to-date information on the eruption comes from the people on the spot at the Virunga National Park: an entry dated 5 January at the gorillacd blog (including dramatic aerial photographs) reports that lava had travelled 21 km from the vent, but a comment on that entry dated 7 January updates this with information from the UN to say that the advance of the lava has slowed, with only 100 metres of advance in the last 24 hours, not because the eruption rate has slowed – the activity of the volcano remains intense – but because the lava front has widened from 15 metres to about 200 metres. More news and links to sources of information for this eruption can be found at OpEdNews: ‘Congo volcano still active’.

‘The Virunga National Park, home to 200 of the world’s 720 mountain gorillas, is in the path of molten hot lava spewing from a volcano that has erupted in the eastern Democratic Republic of Congo’, reports redOrbit (lava that is molten and hot is recognized by volcanologists as the worst kind). The New Zealand Herald observes that the park is ‘home to a spectacular range of mega fauna’ and reports that ‘the eruption has been “very destructive” to the chimpanzee range’ – and also says that Nyamuragira is ‘believed to be the most active volcano in the world’. If so, this is an erroneous belief. ITN reports that ash is contaminating local water supplies, leading to an increase in local people suffering cholera and diarrhoea. The New Scientist has chosen to headline its report on the Nyamuragira eruption ‘Troops protect chimps from volcano lava’, which conjures up some weird images but is in fact a reference to the United Nations force in Congo (MONUC) offering to lend aircraft to the park authorities to help them monitor the progress of the eruption and – as far as possible – protect the park’s population of endangered chimpanzees from its effects.
