Possibly owing to gas drilling on the Indonesian island of Java, a
"mud volcano" has eveloped. and
rendered four square miles (ten square kilometers) of countryside
uninhabitable for years.
A team of British researchers says the deadly upwelling
began when an exploratory gas well punched through
a layer of rock 9,300 feet (2,800 meters) below the surface, allowing
hot, high-pressure water to escape.
The water carried mud to the surface, where it has
spread across a region 2.5 miles (4 kilometers) in diameter
in the eight months since the eruption began. Although the eruption
isn't as violent as a conventional volcano,
more than a dozen people died when a natural gas pipeline ruptured.
An unusual feature of the Indonesian eruption is that
it involves a very thin, liquid mud.
That is unfortunate, because the thin mud could flow for long distances,
increasing the devastation.
The mud is apparently being eroded out from deep underground,
creating a cavern. That means that the
land around the volcano might collapse to form a crater.

an article by Richard A. Lovett for National Geographic News
It was on May 29th, 2006 that the first residents
first witnessed stinking, hot mud shooting from the earth
180 meters (590 feet) from the drilling rig of the Lapindo company.
What began as a stinking puddle of mud soon turned into a pond, the
pond turned into a lake and the lake
turned into a small inland sea. Despite the local residents' efforts
to protect themselves and their homes with sandbags, sludge levels
continued to rise. One night the hot mud crept into nearby houses
for the first time.
In June, the volcano spit out an average of 5,000 cubic meters (178,571
cubic feet) of mud a day --
enough to fill 150 garbage trucks.
In July, that amount increased five-fold, to a daily discharge volume
of about 25,000 cubic meters
In August, daily production jumped to 50,000 cubic meters (about 1.8
million cubic feet).
By September, the mud hole's average daily output amounted to 125,000
cubic meters
(4.5 million cubic feet), enough to transform a soccer field into
a pool of mud 17 meters (56 feet) deep.

So far, refugees have had enough time to take along their most valuable
possessions. But what they were
forced to leave behind is even more telling, as toys, shoes, mattresses
and canned goods float on the
surface of the dense liquid. The list of victims has not included
any human lives, only 1,605 chickens,
30 goats and 2 dairy cows.
Meanwhile, workers have begun installing steel pipes to pump water
and mud from the many catchment basins.
Workers are dredging a canal between one of the largest basins and
the nearby Porong River, as part of a plan to
divert new mud into the river and into the ocean 20 kilometers (12
miles) away. But because the river has very
little slope, experts fear that it could quickly silt up and flood
its banks.
Environmentalists are opposed to the plan because the flood of sediment
could endanger mangroves, fish and fishermen.

an article in Der Spegel
An Indonesian court on Thursday rejected a lawsuit
brought by environmentalists against an energy company
alleged to have caused a mud volcano that has displaced thousands
in East Java province. The South Jakarta district
court ruled that the mudflow in Sidoarjo district was a "natural
disaster", and not caused by gas drilling by Lapindo Brantas
as alleged by Friends of the Earth Indonesia.

The mud volcano that forced more than 15,000 people to abandon their
homes on the Indonesian island of Java
in 2006 has breached the barriers built to contain it, causing further
damage.
It was on Thursday, January 3rd, when
hot, foul-smelling mud began to flow into the area, covering the nearby
railway tracks and a main road. At least 10
vehicles were buried by one-metre deep mud.
The newly affected area is about 20
km from Surabaya, Indonesia's second-largest city. But thousands of
homes and
factories in an area four times the size of Monaco have been submerged
by the hot mud since it first started to erupt.

135
residents living near a mud volcano that has been spewing geiser-like
eruptions of hot, black sludge since mid-2006
were forced to flee after heavy rain caused dams surrounding the disaster-zone
to breach.
Railway
tracks and a major road near Porong, a village in East Java province,
were partially submerged before the
watery mud receded.
The government has made several attempts to contain
or stop the mud, but none has been successful.
