AKARTA: The Jakarta administration is planning to build two more subsidence-monitoring stations in order to accurately evaluate the level of land subsidence in various locations in the capital city.
The head of the Industry and Energy Agency's geology and mineral resources Department, Agus Saryanto, said on Friday that the city currently had three subsidence-monitoring stations that used extensometers.
The three existing stations are located on Jl. Tongkol, North Jakarta; Jl. Jatibaru, Central Jakarta; and Jl. Perintis Kemerdekaan, East Jakarta. The devices were installed in eight different land levels to a depth of 300 meters.
'Jakarta should have at least five stations. Therefore, we will build two more this year,' he said, as quoted by beritajakarta.com.
He added that they would be built in Rawa Buaya in West Jakarta and the western part of Jakarta Bay.
Agus said the two stations would use the global positioning system (GPS) to measure any subsidence. The technology would monitor the coordinates of certain spots that would be changed periodically.
'We have been measuring 68 spots out of 200 planned in Jakarta,' he said.
