The mystery of Lusi

The struggle to discover the cause of the eruption of a mud volcano has vital importance for the loc

Volcanoes are usually stately and sometimes violent. Great mountains with smooth slopes and circular calderas, they lie dormant for centuries, or give off occasional wisps of steam and, more rarely, surges of lava and clouds of ash. And every now and then, one of them explodes spectacularly.

But the volcano that erupted at 5am on 29 May 2006 in Porong, Indonesia, was different; no mountain, just a spreading lake of simmering mud and a 30m plume of sulphurous steam. Up to 50,000 people lost their homes, more than a dozen villages were submerged and two dozen factories abandoned. Rice paddies and shrimp ponds were inundated, roads and railways diverted. The death toll so far is 13, killed when a gas pipeline ruptured.

At its peak, the mud volcano, called Lusi, pumps out 150,000 cubic metres a day, enough to fill Wembley Stadium in about three weeks. And it’s been gushing for nearly two and a half years, with no end in sight.

One recent study by a Durham University-led team considered what Lusi would be like if it keeps erupting for another decade. Attempts to cork the volcano by dropping thousands of concrete balls linked by chains into the vent failed completely. Environmentalists fear that diversion of the mudflow into the Porong river will destroy the local fisheries. Meanwhile the levees keep rising.

Mud volcanoes are not well understood, partly because they usually occur on the seabed. What is clear is that a hot, high pressure reservoir of liquid, in this case mostly water, broke through a rocky cap and began percolating through a layer of clay, turning it into mud and carrying it up to geyser forth at the surface.

The cause of this disaster has generated scientific, legal and political debates as heated as the 60C eruption. Two hypotheses are in play, one is that the magnitude 6.3 Yogyakarta earthquake, which killed 6,000 people two days earlier and 260km away, triggered Lusi. The other is that the Banjar Panji-1 drilling rig operated by PT Lapindo Brantas, which was exploring for natural gas just 150 metres from Lusi’s main vent, set it off.

The legal and political arguments swirl around this central scientific issue. Legally the question is who should pay for dealing with the disaster and compensating the victims. If the drilling was at fault, the companies involved should cough up. If it was a consequence of the earthquake, the government is responsible. The stakes are high; the IMF estimates the cost of Lusi at some £2bn.

And that’s where the politics comes in. Lapindo is 50 per cent owned by Energi Mega Persada, part of the business conglomerate controlled by the family of Aburizal Bakrie, Indonesia’s Co-ordinating Minister for the People’s Welfare. Mr Bakrie has been criticised for distancing himself from the disaster, both as a businessman and as a minister. His refusal to visit Lusi prompted angry activists to spray 700kg of mud on his ministry’s gates in Jakarta. Although his family’s company provides food and other aid to the refugees, and has agreed to pay them £240m in compensation, they denounce it at every turn.

The scientific question came to the fore again at the Geological Society of London on 22 October. Proponents of the earthquake hypothesis, employed by the oil companies, claimed that evidence from their well proved its innocence.

Bambang Istadi, a geologist and exploration manager at Energi Mega Persada, argued that if the 2,800m borehole was guilty, a powerful pressure spike, called a kick, would have been observed. Although there was a spike, he said the roughnecks brought it under control in less than an hour, before it could damage the rock formation. Pressure tests since then have shown that the well is intact; with no leaks in or out. Nor is there any evidence of an underground blowout in the formation surrounding the well; if there had been, the borehole’s temperature would have risen to match the volcano’s and the remaining piece of the drill left in the hole would have slipped down into an opening abyss. So if it wasn’t the well, it must have been the earthquake.

Professor Richard Davies of Durham University’s Centre for Research into Earth Energy Systems, who also made a presentation to the Geological Society, remained unconvinced. The kick was powerful enough to damage the rock formation, he argued, and the lower portion of the well had not been sheathed to prevent such problems. The evidence cited by Mr Istadi can be explained if the massive upheaval when the volcano was triggered resulted in the well becoming pressure sealed from what was going on around it. And crucially, the earthquake was too far away and too weak to have caused the mud volcano. So if it wasn’t the earthquake, it must have been the drilling.

The scientific question, then, is far from settled. But progress is being made. So confident are they of their data, that Mr Istadi and the companies have agreed to share it with Professor Davies. If one side or the other can carry the scientific argument, the legal and political issues will be clarified too. For the people whose homes have been swallowed by Lusi, that can only be good.

Ken Livingstone says publicly what many are saying privately: tomorrow belongs to John McDonnell

The Shadow Chancellor has emerged as a frontrunner should another Labour leadership election happen. 

“It would be John.” Ken Livingstone, one of Jeremy Corbyn’s most vocal allies in the media, has said publicly what many are saying privately: if something does happen to Corbyn, or should he choose to step down, place your bets on John McDonnell. Livingstone, speaking to Russia Today, said that if Corbyn were "pushed under a bus", John McDonnell, the shadow chancellor, would be the preferred candidate to replace him.

Even among the Labour leader’s allies, speculation is rife as to if the Islington North MP will lead the party into the 2020 election. Corbyn would be 71 in 2020 – the oldest candidate for Prime Minister since Clement Attlee lost the 1955 election aged 72.

While Corbyn is said to be enjoying the role at present, he still resents the intrusion of much of the press and dislikes many of the duties of the party leader. McDonnell, however, has impressed even some critics with his increasingly polished TV performances and has wowed a few sceptical donors. One big donor, who was thinking of pulling their money, confided that a one-on-one chat with the shadow chancellor had left them feeling much happier than a similar chat with Ed Miliband.

The issue of the succession is widely discussed on the left. For many, having waited decades to achieve a position of power, pinning their hopes on the health of one man would be unforgivably foolish. One historically-minded trade union official points out that Hugh Gaitskell, at 56, and John Smith, at 55, were 10 and 11 years younger than Corbyn when they died. In 1994, the right was ready and had two natural successors in the shape of Tony Blair and Gordon Brown in place. In 1963, the right was unprepared and lost the leadership to Harold Wilson, from the party's centre. "If something happens, or he just decides to call it a day, [we have to make sure] it will be '94 not '63," they observed.

While McDonnell is just two years younger than Corbyn, his closest ally in politics and a close personal friend, he is seen by some as considerably more vigorous. His increasingly frequent outings on television have seen him emerge as one of the most adept media performers from the Labour left, and he has won internal plaudits for his recent tussles with George Osborne over the tax bill.

The left’s hopes of securing a non-Corbyn candidate on the ballot have been boosted in recent weeks. The parliamentary Labour party’s successful attempt to boot Steve Rotheram off the party’s ruling NEC, while superficially a victory for the party’s Corbynsceptics, revealed that the numbers are still there for a candidate of the left to make the ballot. 30 MPs voted to keep Rotheram in place, with many MPs from the left of the party, including McDonnell, Corbyn, Diane Abbott and John Trickett, abstaining.

The ballot threshold has risen due to a little-noticed rule change, agreed over the summer, to give members of the European Parliament equal rights with members of the Westminster Parliament. However, Labour’s MEPs are more leftwing, on the whole, than the party in Westminster . In addition, party members vote on the order that Labour MEPs appear on the party list, increasing (or decreasing) their chances of being re-elected, making them more likely to be susceptible to an organised campaign to secure a place for a leftwinger on the ballot.

That makes it – in the views of many key players – incredibly likely that the necessary 51 nominations to secure a place on the ballot are well within reach for the left, particularly if by-election selections in Ogmore, where the sitting MP, is standing down to run for the Welsh Assembly, and Sheffield Brightside, where Harry Harpham has died, return candidates from the party’s left.

McDonnell’s rivals on the left of the party are believed to have fallen short for one reason or another. Clive Lewis, who many party activists believe could provide Corbynism without the historical baggage of the man himself, is unlikely to be able to secure the nominations necessary to make the ballot.

Any left candidate’s route to the ballot paper runs through the 2015 intake, who are on the whole more leftwing than their predecessors. But Lewis has alienated many of his potential allies, with his antics in the 2015 intake’s WhatsApp group a sore point for many. “He has brought too much politics into it,” complained one MP who is also on the left of the party. (The group is usually used for blowing off steam and arranging social events.)

Lisa Nandy, who is from the soft left rather than the left of the party, is widely believed to be in the running also, despite her ruling out any leadership ambitions in a recent interview with the New Statesman.However, she would represent a break from the Corbynite approach, albeit a more leftwing one than Dan Jarvis or Hilary Benn.

Local party chairs in no doubt that the shadow chancellor is profiling should another leadership election arise. One constituency chair noted to the New Statesman that: “you could tell who was going for it [last time], because they were desperate to speak [at events]”. Tom Watson, Caroline Flint, Chuka Umunna, Yvette Cooper, Andy Burnham and Liz Kendall all visited local parties across the country in preparation for their election bids in 2015.

Now, speaking to local party activists, four names are mentioned more than any other: Dan Jarvis, currently on the backbenches, but in whom the hopes – and the donations – of many who are disillusioned by the current leadership are invested, Gloria De Piero, who is touring the country as part of the party’s voter registration drive, her close ally Jon Ashworth, and John McDonnell.

Another close ally of Corbyn and McDonnell, who worked closely on the leadership election, is in no doubt that the shadow chancellor is gearing up for a run should the need arise.  “You remember when that nice Mr Watson went touring the country? Well, pay attention to John’s movements.”

As for his chances of success, McDonnell may well be even more popular among members than Corbyn himself. He is regularly at or near the top of LabourList's shadow cabinet rankings, and is frequently praised by members. Should he be able to secure the nominations to get on the ballot, an even bigger victory than that secured by Corbyn in September is not out of the question.
