The volcano Mount Sangeang Api in the Lesser Sunda Islands has just erupted, sending a huge ash cloud 12 miles into the air.
Wikipedia describes Sangeang Api as a volcano complex with 2 active cones, Doro Api 1,949 metres (6,394 ft) and Doro Mantoi. 1,795 m (5,889 ft). Indonesia has a number of very active volcanoes, including volcanoes which threaten major cities, such as the infamous Mount Merapi.
Merapi, which has erupted several times in the last decade, is located just 17 miles from the city of Yogyakarta, home of 2.5 million people.
Near equatorial volcanoes like Sangeang Api are useful to global warming modellers, as the ash cloud can usually be detected in both hemispheres. They provide a convenient excuse for the short term cooling of the entire Earth.
