The Lusi (Lumpur Sidoarjo) mud volcano, located in Sidoarjo Regency, East Java, Indonesia, has been erupting since 29 May 2006. At its peak, flow rates reached 100,000 cubic meters per day, and the mud rapidly buried more than 700 hectares across a dozen villages. The flow rate has since declined to an average of about 10,000 cubic meters per day.
A large containment dam was built to hold back the mudflow and the inundated areas. Land surrounding the dam remains at risk from subsidence, with ground settlement recorded more than 3 km away.
