Indonesia's disastrous mud volcano is collapsing on itself, according to new research released on the second anniversary of the ever-growing environmental catastrophe.
Each day, 100,000 cubic metres of hot, stinking sludge continues to ooze from the mystifying mud volcano, which burst through the earth two years ago during deep drilling at a nearby exploratory well, linked to Indonesia's richest man and also part-owned by Australian company Santos.
The grey-brown ooze now covers seven square kilometres in heavily populated East Java.
It has swallowed 11 villages, including thousands of homes, businesses, paddy fields and mosques.
