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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
