Drilling, Not Earthquake, Caused Indonesian "Mud Volcano"

A mud volcano which has caused millions of dollars worth of damage was caused by the drilling of a gas exploration well, an international team of scientists has concluded.

The two-year old mud volcano, Lusi, is still spewing huge volumes of mud and has displaced more than 30,000 people.

The most detailed scientific analysis to date disproves the theory that an earthquake that happened two-days before the mud volcano erupted in East Java, Indonesia, was potentially to blame.
