when the rainfall is above normal
Jakarta (ANTARA) – The DKI Jakarta Regional Disaster Management Agency (BPBD) asked the public to be aware of the potential for ground movement at 10 points in South Jakarta and East Jakarta in December 2022.
“To the village head, sub-district head and the community to continue to anticipate the potential for ground movement when rainfall is above normal,” said Jakarta BPBD Chief Isnawa Adji in Jakarta, Thursday.
Isnawa explained that the Center for Volcanology and Geological Hazard Mitigation (PVMBG) has mapped several areas in DKI Jakarta Province to be in the middle zone where it is estimated that there will be ground movement.
The 10 points are South Jakarta, covering the sub-districts of Cilandak, Jagakarsa, Kebayoran Baru, Kebayoran Lama, Mampang Prapatan, Pancoran, Pasar Minggu and Pesanggrahan.

Furthermore, in East Jakarta, covering the Kramat Jati and Pasar Rebo sub-districts.
In that zone, he said, ground movement could occur if rainfall was above normal, especially in areas bordering river valleys, road cliffs or if slopes were disturbed.
Whereas in the high zone, old soil movements can be active again.
Isnawa explained that the estimates of the potential areas for ground movement to occur were compiled based on the results of overlapping the map of the vulnerability zones for ground movement with the forecast map of monthly rainfall obtained from BMKG.
