1. Ethiopia: Gamo Zone Death Toll Reaches 125; Humanitarian Crisis Deepens
The catastrophic landslides that struck the Gamo Zone in Southern Ethiopia on March 10–11 remain the most severe global geohazard event of the month. As of March 18–19, official reports confirm the death toll has risen to 125.
- The Scale: In addition to the fatalities, more than 11,000 people have been displaced across the districts of Gacho Baba, Bonke, and Kamba Zuria. Approximately 190 houses were completely destroyed.
- Trigger: Intense seasonal rainfall acting on steep, volcanic highland slopes.
- Risk Reduction: Prime Minister Abiy Ahmed and religious leaders have called for national solidarity during the ongoing three-day mourning period. The Catholic Bishops’ Conference of Ethiopia (CBCE) and other organizations are mobilizing emergency aid as geologists warn that “delayed failures” are still possible due to total soil saturation.

2. Italy: Mass Evacuations in Calabria Following Major Slope Failure
A large landslide struck the municipality of Crosia (Cosenza Province) on March 17–18, forcing the immediate evacuation of at least 80 residents as debris moved toward the historic town center.
- The Event: Over 220 mm of rain fell within 36 hours, causing the Trionto and Fiumarella rivers to overflow and destabilizing the slopes above Via San Francesco di Paola.
- Impact: Massive volumes of saturated soil detached from the mountain, damaging roads and threatening residential structures. Road closures were also reported in Corigliano, Rossano, and Mandatoriccio.
- Response: The Municipal Operations Center (COC) remains active. Fire brigades from across the region have been doubled to manage over 100 intervention requests as thunderstorms are forecast to continue across Calabria and Puglia through March 20.

3. Global Science: WWA Study Identifies “Social Vulnerability” as Key Landslide Driver
A high-impact technical study released this week by World Weather Attribution (WWA) regarding the February 2026 landslides in Brazil provides a critical framework for global Landslide Risk Reduction (LRR).
- Key Finding: While climate change made the triggering rainfall ~7% more intense, the high death toll (72+) was primarily due to unplanned urban expansion on steep slopes. In Juiz de Fora, 130,000 people live in high-risk zones.
- The “Warning Gap”: The study found that while Cemaden issued accurate technical alerts, topographical barriers limited siren effectiveness, and many residents lacked practical evacuation paths.
- Strategy: The researchers argue that technical monitoring must be paired with incremental adaptation—targeted slope stabilization, improved drainage, and community-level risk education—to be effective.
