Officials fear impact of possible new volcanic eruption
Thousands of people scrambled to flee the Congolese city of Goma on Thursday, some picking their way across landscapes scarred with lava, after officials said a second volcanic eruption could happen any time.
Magma, the molten rock that normally stays beneath the earth's crust, had been detected beneath the city and the adjoining Lake Kivu, Constant Ndima Kongba, the military governor of North Kivu province, said, citing seismic and ground deformation data.
"Given these scientific observations, an eruption on land or under the lake cannot be ruled out at present, and it could occur with very little or no warning," he said.
Thirty-one people were killed on Saturday evening when Mount Nyiragongo, one of the world’s most active volcanoes, sent a wall of orange lava downhill towards the city, destroying 17 villages on the way.
The lava stopped just 300 metres short of Goma airport, the main hub for aid operations in eastern Democratic Republic of Congo.
Much of the city was spared but hundreds of earthquakes since have destroyed buildings and opened cracks in the earth.
Ten neighbourhoods in the east of the city, which lay in the path of lava from the previous eruption in 2002, needed to move to Sake, around 21km to the northwest, Ndima said.
Thousands of people heeded his message, filing out of town on foot, with huge bundles on their heads. Others fled by car, creating traffic jams across the city, or on large boats that took them across Lake Kivu.
On the road north of Goma, a stream of people picked their way across a landscape charred by lava still hot from Saturday's eruption, drone video footage showed.
A spokesman for the national government said at one point that boat traffic had been banned because Lake Kivu was considered dangerous, but a local governor later said the lake would remain open.
Volcanologists in Goma warned earlier on Thursday that, in a worst-case scenario, a volcanic eruption under the lake, accompanied by a large earthquake, could trigger a sudden release of carbon dioxide from the bottom of the lake.
Such an explosion could asphyxiate thousands of people, they said.
Chiara Frisone, a spokeswoman for the United Nations children’s fund, said people were fleeing in every direction.
"There are local people and international organizations as well, it’s quite a chaotic situation," she said, adding that the UN's emergency response teams and local partners were staying in the city.
On Wednesday the UN said it was temporarily relocating around 250 non-essential staff, around half of its aid workers, and about 1,500 of their dependents to the city of Bukavu, around 50km south.
Congo imposed martial law on the region earlier this month to try to stem the bloodshed and widespread insecurity many people still face every day, long after the official end of a civil war in 2003.
Around 3,000 houses were destroyed in Saturday's volcanic eruption and more than 20,000 people left homeless. At least 40 people are still missing.
