Ten-year-old mud volcano baffles scientists

Whether caused by the blowout of a natural gas well, a distant earthquake or something else, the Sidoarjo mud flow is the biggest of its kind in the world.

The world’s most destructive mud volcano was born near the town of Sidoarjo, on the island of Java, Indonesia, just over 11 years ago – and to this day it has not stopped erupting, as The Conversation explains.

The mud volcano known as Lusi started on May 29, 2006, and at its peak disgorged a staggering 180,000 cubic metres of mud every day, burying villages in mud up to 40 metres thick.

The worst event of its kind in recorded history, the eruption took 13 lives and destroyed the homes of 60,000 people. But although the mud is still flowing more than a decade later, scientists are not yet agreed on its cause.


The debate is whether the eruption of Lusi was due to an earthquake several days previously, or down to a catastrophic failure of the Banjar Panji 1 gas exploration well that was being drilled nearby at the time.

Given the huge impact of the volcano on the communities nearby and the fields that were their livelihoods, why are we still unsure of the cause?

    Wikipedia claims it’s ‘man-made’.

    ‘Mud volcanoes are not true igneous volcanoes as they do not produce lava and are not necessarily driven by magmatic activity. The Earth continuously exudes a mud-like substance, which may sometimes be referred to as a “mud volcano”. Mud volcanoes may range in size from merely 1 or 2 meters high and 1 or 2 meters wide, to 700 meters high and 10 kilometers wide.[1] Smaller mud exudations are sometimes referred to as mud-pots. The largest (man made) mud volcano is “Lusi” in Java, Indonesia, which is 10 kilometres (6 mi) in diameter.[bold added]

    To any SJW everything that requires any scientific input to help explain what they are seeing HAS by definition to be man made.

    Surprised no one considered that both the lack of casing combined with the earthquake was the cause. Many systems failures happen that way. The first event isn’t recognized as dangerous, so it is allowed to continue. Which sets the scene for catastrophic failure when the second event occurs.

    For example, a worn part on a car isn’t dangerous for normal driving, but going over a bump at high speed can cause the driver to lose control. So was the problem caused by speed, the bump, or the worn part?
