The geological setting consists of volcanic rock (mainly andesite) covered by a thin layer (1 m) of silt or clay material. In 1982, the local administration of the city of Bandung chose the small valley-head of Leuwigajah, a neighborhood of Cimahi, to locate the largest waste disposal for the urban centre. Most of the uncollected waste was dumped in the rivers (mainly the Citarum River), burned by the population or buried in the backyard.

Out of the whole volume of waste produced in the metropolitan area, only 46% was collected (Sundana ). Household activities produced the highest volume of waste (7700 m 3 per day), followed by industrial waste (3200 m 3 per day) and public facilities (1400 m 3 per day). In 2005, solid waste generation in this region exceeded 14,000 m 3 per day (Sundana ), of which more than half was generated within Bandung city. The waste slide buried 71 houses and killed 143 people.įor decades, several dumpsites have operated in Bandung Metropolitan area, which has approximately 6 million inhabitants. Among these disasters, the second deadliest event in history took place on 21 February 2005 at 02.00 am at the Leuwigajah dumpsite, in the vicinity of Bandung city, Java, Indonesia (Figure 1). Palaypayon and Ohta, Gaillard and Cadag ). in Kettleman, California, in 1988, Cincinnati, Ohio and Coruña, Spain in 1996, or Athens in 2003), but it is only in developing countries that they have led to major disasters: the deadliest event of this type killed 278 people in Payatas in the vicinity of Manila, Philippines in 2000 (Bernardo Merry et al. Such events have occurred in western post-industrial countries (e.g. Despite a wide range of industrial hazardous accidents that have occurred worldwide in and around the vicinity of dumpsites, only a handful of contemporary disastrous solid “wasteslides” or “waste avalanches” have been documented. Stability of landfills is one of the major geotechnical issues in landfill management. Although progressively replaced by alternative methods like incineration, this technique remains very common around the world, especially in developing countries. Iii) the extreme vulnerability of the marginalized scavengers living at risk at the foot of the instable dump.Ī landfill site or dumpsite is a site for the disposal of waste materials by burial. I) a front slope of the dump of about 100% before the failure Resulting of a combination of heavy rainfall and consecutive explosions due to biogas sudden release, this disaster was predictable in reason of The presence of methane within the waste dump was responsible for explosions prior to sliding and for the fire that affects whole sliding mass. Numerous internal slip surfaces, underlined by plastic bags explain the low friction coefficient. The material displays a preferential fabric parallel to the previous topography. ResultsĢ.7 × 10 6 m 3 of waste materials spread 1000 m from the source in a rice field with an average thickness of 10 m. To constrain the movement condition, we studied the internal structure of the source area and realized surveys among stakeholders of the dumpsite and citizen. The morphology of the slide and its trajectory were reconstructed.

A series of aerial photographs were acquired and completed by topographical measures on the ground.

We carried on four field investigations on the site. We explored failure preconditions, triggering mechanisms and local context that conducted to this disaster. Amongst the contemporary disastrous events of this type, only a few have been documented. Second deadliest waste slide in history, it buried 71 houses and killed 143 people. On 21 February 2005 the Leuwigajah dumpsite, Bandung (Java, Indonesia) was affected by a large slide after heavy rainfalls.
