Eruption of mud volcano in Indonesia's Sidoarjo can't be stopped — Russian scientists

JAKARTA, Sept. 30 — Russian scientists said on Thursday that eruption of mud volcano in Indonesia's Sidoarjo City in East Java province that has been lasting since four years ago cannot be stopped as it is caused by a series of seismic activities.

A Russian scientist headed by Dr. Sergey V. Kadurin from the Russian Academy of Science concluded that the activities have reactivated an ancient mud volcano structure that had been formed about 150,000-200,000 years ago.

"We can't stop the nature. It would be lie if some people said that we could stop the phenomenon. It's also not preventable, " he told the press.

Kadurin said that the strong activities have accelerated force to form the mud.

"An earthquake occurred about a year before the mud eruption was one of geological phenomenon that helped the opening of mud channel. And, the earthquake two days before the eruption might be the last kick-off," said Kadurin.

Based on this data, about 10 months before the eruption on July 9, 2005, an earthquake of 4.4 Richter scale with en epicenter on top of the eruption zone occurred.

This was followed by another earthquake of 5.5 Richter scale at 16 days before the eruption within 450 kilometers range. And, two days before the eruption, a 6.3 Richter scale magnitude rocked Yogyakarta province, about 185 kilometers of the mud eruption.

"Based on the findings, we concluded that the mud eruption was caused by combination of seismic disturbances that reactivate an old mud volcano," said Kadurin.

Awang Harun Satyana, senior manager of geology at Indonesia's Executive Agency for Upstream Oil and Gas Business Activities agreed with the findings.

"Earthquake triggered the mud eruption," said Satyana.

He said that based on geographic, historical and folklore facts, it is concluded that the mud eruption was not something new.

"Indonesia experienced such phenomenon million years ago and hundred years ago," he said. (PNA/Xinhua) vcs/utb
