Jakarta – The Meteorology, Meteorology and Geophysics Firm (BMKG) and the Indonesian Institute of Sciences (LIPI) are collectively developing a precursor system to find earthquakes having a magnitude above 6.5.
” Starting in 2021, a joint research study is being carried out by BMKG and LIPI to study earthquake precursors, focusing on earthquakes that have the prospective to cause damages,” Rahmad Triyono, Head of the Center for Seismology, Prospective Geophysical Engineering and Time Indications of BMKG,, stated in a declaration here on Sunday.
Triyono discussed that the research study is to upgrade precursors owned by BMKG and to make them much better.
” Currently, the precursors established by BMKG have not been able to effectively or precisely identify earthquakes with a big magnitude or with strength of more than 6.5,” he stated.
Nevertheless, although the existing system has actually not been able to properly find possibly devastating earthquakes, the precursors have a fairly good level of precision (between 60-70 percent) for earthquakes with a magnitude of 5 to 6.
The precision of earthquake precursors developed by BMKG utilizing earth magnets work much better, with an accuracy of 80-90 percent, when the earthquakes have magnitude of around or less than 5.
” The level of precision for identifying major earthquakes is still bad, but for earthquakes with a magnitude of around 5, it has started to increase,” he kept in mind.
Earthquake precursors using the Earth’s magnetic method are still being developed, but the information has been restricted to BMKG internal use, due to the fact that most of the earthquakes with a magnitude of 5 were not harmful or not even felt by the public, for this reason BMKG continues to develop it.
” Hence, this precursor will have the ability to predict earthquakes with a magnitude above 6,” he said.
” In addition, (BMKG and LIPI) will also establish the earthquake precursors by combining numerous methods to verify the parameters of the earthquake precursors that have actually been established, such as Seismic Vp/Vs, earthquake history, Radon, soil temperature, and TEC (Overall Electron Material),” Triyono said.
