Concerns mud volcano now spewing explosive gas

Indonesia
Indonesians living near a devastating mud volcano that has spewed sludge for nearly two years say they now have to contend with flammable gas. Highly concentrated methane is pouring into nearby residential areas. Some locals are too afraid to cook at home in case they cause an explosion. Officials are determining whether the gas originates from the mud volcano, or is produced from sewage in the pipes. The mudflow, near Indonesia's second-largest city of Surabaya in East Java, has displaced about 15,000 households since it began spewing in May 2006.
