"There is still volcanic activity, but a considerable number of people are coming back," said a UN peacekeeping officer in Goma, where the civil war broke out in 1998. "There is still lava flowing into the town and outside the town. Basically it's cut a swathe 50-60 metres wide through the town, on either side for 10-15 metres wooden houses have burnt." The lava, he added, was flowing into Lake Kivu.
