Affected Areas and Incident Site Mapping
- The 32 foot-high dam of Situ Gintung, which was holding back around 70 million cubic feet of water at the Pesanggrahan river, was built up to a century ago, under the Dutch colonial rule.
- Little maintenance had been carried out on the dam since then, and many dams in Indonesia are in similar state.
- The collapse of the Situ Gintung was caused by the inability to accommodate more water on account of heavy rains which poured down in some districts in Banten and West Java provinces all night long on Thursday, 26th March 2009.
- The dam was first overflown and then burst out, because the foundation was not made of concrete.
- Cracks had already been discovered at the bottom of the embankment last February 2008. The administration had since prepared evacuation routes in case of flooding and also held a flood evacuation simulation exercise last year.
- It was also stated that the incidents of Situ Gintung was probably due to lack of routine inspections. Therefore, the Governor of Jakarta called for immediate inspections for all 26 dams in the capital.
- The landslide occurred up on the highlands, bringing down debris such as mud and uprooted trees as the flood washes up the affected areas.
- The water level reached up to 1 meter high.
- Heavy downpour had caused mudslides across several areas in the province, including East Agam, Sawalunto, Salimpauang and Pasir Laweh.

- The estimated economic lost affected by the disaster was Rp 75 billion (US$ 6.5 million)
- In 1997, the similar incident occurred in Tanah Datar, and had caused 21 persons dead.
