A volcano in the Indian Ocean's Comoro islands was still spewing lava Wednesday almost two weeks after it began erupting, a senior vulcanologist said.

Hamid Soule, who heads the observatory monitoring Mount Karthala, said there was a 15-metre (45-foot) fountain of lava in the volcano's crater, and that although the eruption was weakening, there was still a state of alert.

Just over 175,000 people were still without potable water, and the local Red Crescent Society was continuing to clean ash from open water tanks.

The volcano lies on the country's largest island, Grande Comore, about 15 kilometres (nine miles) from the capital Moroni.
