Expert challenges earthquake theory behind Indonesian mud volcano

01.08.2007
A leading expert today repeated his assertion that an Indonesian mud volcano was almost certainly manmade despite a new study claiming the eruption might have been triggered by an earthquake.

Professor Richard Davies of Durham University’s Centre for Research into Earth Energy Systems (CeREES), said the volcano, known locally as Lusi, was most likely caused by the drilling of a nearby exploratory borehole (1) looking for gas.

He reiterated the findings of a Durham University-led study, first published in the February issue of US Journal GSA Today, following publication of a new paper led by the University of Oslo which said the eruption in May 2006 might have been caused by an earthquake that occurred two days earlier.

The Durham-led research discounted the effect of the earthquake as a cause of the eruption.

Professor Richard Davies, of Durham University’s Centre for Research into Earth Energy Systems (CeREES), said: “There were several problems with the exploration well prior to the eruption of the mud volcano, but it was when they started to pull the drill bit out of the hole that they probably sucked gas and water into the wellbore.

“We have calculated that a water or gas influx would have caused a critical increase in the pressure in the hole, sufficient to fracture the rock strata underground.

“It is very unlikely that the Yoyakarta earthquake had a significant role to play in the development of the mud volcano.

“We still maintain that the mud volcano was most likely triggered by operations during drilling. There is no need to evoke an earthquake trigger for this.”

Lusi first erupted on May 29 2006 in the Porong sub-district of Sidoarjo in Eastern Java, close to Indonesia’s second city of Surabaya.

The volcano has continued to spew out an estimated 150,000 cubic metres of mud every day and now covers an area of 10 square kilometres.

Around 20,000 to 30,000 people have lost their homes and factories have been destroyed. Thirteen people have also died as a result of a rupture in a natural gas pipeline that lay underneath one of the holding dams built to retain the mud.

(1) The borehole is owned by Indonesian oil and gas company Lapindo Brantas.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
