Mud Volcano - Foto stock

The Sidoarjo mud flow or Lapindo mud is the result of an erupting mud volcano in the subdistrict of Porong, Sidoarjo in East Java, Indonesia that has been in eruption since May 2006. It is the biggest mud volcano in the world and is still erupting mud in this July 2017 aerial photo over 11 years since it first erupted. Responsibility for the eruption was credited to the blowout of a natural gas well drilled by PT. Lapindo Brantas, although some scientists and company officials contend it was caused by a distant earthquake. At its peak the mud volcano spewed up to 180,000 m³ of mud per day. By mid August 2011, mud was being discharged at a rate of 10,000 m³ per day, with 15 bubbles around its gushing point. This was a significant decline from the previous year, when mud was being discharged at a rate of 100,000 cubic metres per day with 320 bubbles around its gushing point. It is expected that the flow will continue for the next 25 to 30 years. Although the Sidoarjo mud flow has been contained by levees since November 2008, resultant floodings regularly disrupt local highways and villages, and further breakouts of mud are still possible.
