Based on information from the Center for Volcanology and Geological Hazard Mitigation (PVMBG), there are 10 areas in Jakarta Province, which are in the middle zone which includes South Jakarta and East Jakarta.
For South Jakarta, it covers sub-districts of Cilandak, Jagakarsa, Kebayoran Baru, Kebayoran Lama, Mampang Prapatan, Pancoran, Pasar Minggu, and Pesanggrahan. Meanwhile, East Jakarta includes Kramat Jati and Pasar Rebo areas.
