Experts say the mudflow in Sidoarjo in Indonesia will expire at the end of this decade , sooner than previously thought .
This study is based on satellite data records that indicate soil conditions changed in response to the material surface.
The researchers say the mudflow lose pressure quickly .
The eruption that began in the region of East Java Porong in 2006 is the largest of similar events .
Mud , dangerous has led thousands of people to evacuate and caused economic losses of U.S. $ 4 billion or Rp47 , 9 trillion .
Initially , more than 100,000 tons of sludge to surface . Mudflow decreased up to ten -fold , and an analysis based on Japanese research satellite at ground level estimates a ten-fold decrease may occur in the next few years .
" In 2017 , the overflow will be weakened , " said Professor Michael Manga of the University of California at Berkeley , U.S. .
decline
"The numbers are definitely , 1,000 tons per day - as much as thousands of mud flatbed truck per day . Amount is too little to be able to cause harm , ( but) it may still be interesting to be a tourist destination , " he told BBC News .
" I expect the ( then ) that if the eruption fell on a certain number , will clog themselves and stop erupting . "
Previous estimates predict Sidoarjo mud will continue to overflow up to 25 years or more .
Prof. Manga spoke in San Francisco at a meeting of the world 's largest Earth experts , the American Geophysical Union ( AGU ) .
He and his colleagues used a technique known as interferometric synthetic aperture radar ( InSAR ) to access the evolution of Sidoarjo mud eruption .
This research was carried out by combining a number of images of the volcano satellite images from space taken by the Japanese ALOS satellite , to ensure changes in the surface around the volcano .
For several years , the land surface drops ten inches of material due to encouragement from the earth to the surface of the ground . However , the overflow continues to show a decline .
