1. Indonesia: Fatal Waste Mound Collapse in Bekasi; Search Operations Conclude
A devastating “anthropogenic landslide” occurred on March 8–9 at the Bantargebang Integrated Waste Processing Site, Indonesia’s largest landfill. Unlike traditional soil-based landslides, this event involved the catastrophic failure of an unstable waste mountain.
- The Event: Torrential overnight rains triggered a collapse of saturated refuse mounds. Search and rescue operations officially concluded on March 10 after the final victim was recovered.
- Impact: 7 confirmed fatalities; 6 survivors. The final victim was found buried under several meters of waste late Monday.
- Engineering Context: The landfill, roughly the size of 200 football fields, has reached its capacity. The event highlights the critical need for monitoring pore-water pressure in non-traditional slopes like waste piles, which behave similarly to saturated geological formations but with higher chemical and organic complexity.

2. Brazil: 72 Deaths in Minas Gerais as “Residual Risk” Threats Move to São Paulo
While the most catastrophic landslides in Juiz de Fora occurred in late February, the crisis has transitioned into a persistent monitoring phase. As of March 10, the death toll stands at 72, with thousands still displaced.
- Trigger: Record-breaking February rainfall (over 750 mm) has left hillsides in a state of “total saturation.”
- Current Threat: A Crisis Office in São Paulo has been activated through March 11. Even moderate rainfall is now considered a high-risk trigger for secondary landslides because existing soil tension is at its limit.
- Risk Reduction: Authorities are advising residents to monitor “silent indicators”: leaning utility poles, new wall cracks, and the sudden appearance of muddy springs at the base of slopes.

3. DR Congo: Rubaya Mine Tragedy Surpasses 600 Deaths in Recurring Collapses
The situation at the Rubaya coltan mines in North Kivu has evolved into a global geohazard catastrophe. A third major landslide on March 7 at the Gakombe site followed the massive March 3 failure.
- Trigger: Exceptional rainfall acting on artisanal shafts and open pits that lack any geotechnical stability measures or drainage systems.
- Global Impact: Rubaya accounts for nearly 15% of global tantalum supply. The repeated failures demonstrate how “red zones” (conflict areas) create a vacuum in risk reduction, leading to massive loss of life—including over 70 children in the latest week alone.
- Critical Issue: The site has been reclassified as a “red zone” by the government, prohibiting mining, but thousands continue to work in unstable conditions due to economic necessity.

- Process Diagram: For your blog, a diagram showing the I-D (Intensity-Duration) Threshold would be excellent to explain why even “moderate” rain is now dangerous in Brazil.
- Satellite Analysis: You can reference Planet Labs imagery (often featured on the Eos Landslide Blog) to show the “before and after” scarring of the Rubaya mountain.
