In an update to the story we covered yesterday, the risk of further eruptions from the Nyiragongo volcano has led DR Congo authorities to order the evacuation of parts of the city of Goma, resulting in an immediate exodus of tens of thousands of people. The AFP news agency quotes the local military governor as saying that “current data on seismicity and the deformation of the ground indicate the presence of magma under the urban area of Goma, with an extension under Lake Kivu”. “We can’t rule out an eruption on land or under the lake, which could happen very soon and without warning,” he warned, adding that there were also supplementary risks associated with the interaction between magma and water in Lake Kivu.
