Mud volcano still producing mud flow after 15 years

The mudflow in Cedar Ojo, Eastern Java, covers over 6.5 square kilometers, displacing 60,000 people. It releases 100,000 tons of methane annually. While some blame an earthquake, others attribute it to drilling. Mitigation efforts include redirecting mud into a river and building an embankment, though challenges persist.
