The Sidoarjo mud flow, Sidoarjo, Indonesia

The Sidoarjo mud flow or Lapindo mud is a mud volcano in the subdistrict of Porong, Sidoarjo in East Java, Indonesia that has been in eruption since May 2006. The Sidoarjo Mud Flow is the biggest mud volcano in the world, created by the blowout of a natural gas well drilled by PT Lapindo Brantas, although company officials contend it was caused by a distant earthquake. In August 2012, Geologists definitely stated that the Sidoarjo mudflow was caused by drilling operation misconduct which only used a quarter of the height of drilling wallpipe and was not caused by an earthquake 275 kilometer away. This was stated by a Constitutional Court concerned with the National Budget to bear a part of the disaster fund.
