A volcano erupted Monday in eastern Indonesia, spewing ash as high 2 kilometres into the air, an official said. There is no necessity yet to evacuate people who live near the 1,578-metre volcano, said National Disaster Management Agency spokesman Sutopo Purwonuhroho. The volcano has erupted several times since January. It has been on high alert status since July when it began showing increased activity. Indonesia has about 500 volcanoes, 128 of them classified as active and 65 listed as dangerous.
