Earthquake preparation period that lasted several weeks leave many traces. One was the emergence of radon gas, which is odorless and colorless, from the bowels of the earth. Indonesian Institute of Sciences (Lembaga Ilmu Pengetahuan Indonesia / LIPI) has a tool that can detect an increase in radon from the soil.
Hydrogeological researchers from the Research Center Geotechnology LIPI, Rahmat Fajar Lubis, said the gas was surfaced with ground water that is pulled up to the surface before an earthquake. Liquid stored in the ground this time ascertained contain high levels of radon. As a result, will increase the level of radioactivity in the earth's surface, just before the earthquake.
The most convincing evidence came in 1995, when a 6.8 magnitude earthquake rocked Kobe, Japan. The counter is attached radon in some spring water showed increased radioactivity few months before the earthquake. "Since the Kobe earthquake, a number of ahii assumed earthquake was preceded by an increase in radioactivity," says Fajar, some time ago.
Reality on the ground to support this assumption. Many large earthquakes are preceded an increase in radioactivity, so it opens great opportunities for researchers to predict earthquakes using radon enumerator.
This year LIPI brings three instruments enumerator radon, which is RAD7, RAD H20, and RAD Aqua. Taken together, these three instruments could be increased radioactivity radon monitoring tool.
Unfortunately, LIPI has only one unit of advanced equipment worth Rp. 170 million. Enumerator radon should be used interchangeably by researchers to study the groundwater conditions in various regions in Indonesia. To determine the amount of radioactive substances, radon counter should be installed in the spring around the fault. The spring is the best location to get the soil seepage water containing radioactive substances.
Enumerators will take samples of water radon emanating from springs and spray into a closed container. The detector then detect radon gas is sprayed into the container. "Towards the earthquake, we expect an increase in radon gas content," he said.
To investigate the earthquake, LIPI plan to install this tool in the area of ??Lembang. Limitations of the tool makes the enumerator radon can not be installed permanently in Indonesia, which has hundreds of fault. "To detect an earthquake, should have this tool installed static," he said. *** [ANTON WILLIAM | KORAN TEMPO 3707]

How to predict earthquakes?
Towards the quake, the earth turns. Radioactive gases out of the ground and ionize molecules. The presence of ionized molecules in the Earth's surface attract the ions in the upper atmosphere, both the voltage difference reaches 250-500 kilovolts. Once attracted to the bottom, the top layer of the atmosphere so that the ion deficient radar will observe the decrease in ion concentration. Alternatively, the expert can read the increase in radioactivity in the earth's surface.
Since when did this change occur?
Several weeks before the earthquake. Could one or two weeks earlier.
What else can be known of this detection?
Monitoring of the atmosphere can give warning that an earthquake is getting closer. While monitoring the concentration of radon allows researchers to know the earthquake preparation area. Formula Dobrovolksy lets researchers know the magnitude quake will happen. The formula is simple: rho (P) = 10^(0.43 M), where rho is the radius of earthquake preparation area and the "M" is the magnitude of the earthquake.
Many scientists reject the notion that earthquakes be predicted?
This assumption immoral. They proposed houses are built as solid as possible. But this is just the solution for the developed countries with high economic capacity of the population. Then, how the fate of hundreds of thousands of residents of developing countries and the poor are threatened by earthquakes. Therefore, must develop ways mempfediksi earthquake.
Your earthquake prediction can be applied?
There are still some problems to build up this theory, such as problems of equipment limitations. In addition, it takes a variety of approaches (multiparameter approach) is more complex than previously thought.
Earthquake prediction can be applied in Indonesia?
Of course. Indonesia is an interesting place to learn this, your country is located in an area that experienced anomaii equator with a complex nature. Electric field changes very little could have an effect on the environment. Indonesia experts can monitor the area of the earth's surface to the ionosphere using various tools, such as radon counter, measuring electrical parameters of the atmosphere, satellite monitoring network meteorologij measurement and monitoring ionospheric thermal anomaly. Ionosonda on atmospheric radar you have to complete the spectrum of this research. Currently China also is building 100 ionospheric radar to monitor the condition of seismo-ionosphere. *** [ANTON WILLIAM | KORAN TEMPO 3707]
