World's largest mud volcano to last 26 years

In 2007 and 2008, a team of scientists led by Professor Davies produced evidence that drilling caused the mud volcano. The company involved, Lapindo Brantas, has disputed the claim that a nearby gas exploration well was the trigger for the volcano, instead blaming an earthquake which happened 174 miles away. Efforts to stem the flow of the mud volcano, including plugging the crater with concrete balls failed. The creation of giant dams has contained most of the subsequent mud flow.
