Man Made Volcano

As if Indonesia did not have enough environmental problems; 340000 flee deadly floods in Jakarta, now we find out that the mud spewing volcano that erupted last year is a man-made phenomena.

Drilling for gas most probably caused the eruption of an Indonesian mud volcano, forcing the evacuation of thousands of people, scientists report.

"[The eruption] appears to have been triggered by drilling of over-pressured porous and permeable limestones at depth of around 2830 metres below the surface," says the study, the first published on what caused the eruption.

The study, which appears in the February issue of the journal GSA Today, adds that the volcano has been disgorging 7000-150,000 cubic metres of mud every day since it erupted in May last year.

Such pressures, coupled to the local geology, suggest the flow "will continue for many months and possibly years to come", warn the UK researchers, led by Professor Richard Davies from the University of Durham.

In the coming months, sag-like subsidence several kilometres wide will occur, and around the main vent there is likely to be "more dramatic collapse", forming a crater, the study adds.

An area of at least 10 square kilometres around the volcano will be uninhabitable for years, and over 11,000 people will be permanently displaced, it says.

Add to that the wildfires started by slash and burn operations for palm oil plantations and the continuing disruption and displacement from the 2004 Tsunami and Indonesia is an ongoing environmental disaster.

But do plan to take your holidays there, I hear it is quite nice otherwise.
