A 2013 report indicated that for nearly seven years the mudflow had been wreaking havoc in the livelihoods of Porong residents in particular and on the Sidoarjo economy as a whole. The mudflow had also buried more than 6000 hectares of land, displacing 39,700 people and submerging three subdistricts, 12 villages, 11,241 buildings and 362 hectares of rice fields.
