The inventory was created through a collaborative effort involving researchers from multiple institutions. By coordinating activities across teams, we rapidly generated spatial data to support disaster response, while also providing a robust and reliable database for scientific analysis.

- This research underscores the urgent need for systematic documentation and high-quality landslide databases to guide effective disaster prevention and management strategies. 📢

📝 Highlights:
- An unprecedented precipitation event between April and May 2024 impacted millions. 📊
- 15,376 landslides were recorded (the largest number ever documented in Brazil) ⚠️
- 96% of municipalities were affected, spanning ~18,000 km² with 16,862 initiation points. 🌆

The biggest landslide event in Brazil: preliminary analysis of the Rio Grande do Sul mega disaster in May 2024 - Landslides An unprecedented precipitation event in Rio Grande do Sul, Brazil, between April and May 2024 caused widespread floods and landslides. This extreme event impacted 96% of the state’s municipalities, affecting approximately 2.4 million people and resulting in 183 deaths. This article reports the magnitude of this extreme event, focusing on the preliminary results of a comprehensive landslide inventory. Our analysis revealed that this event triggered 15,376 landslides across approximately 18,000 km2, with 16,862 landslide initiation points. This event represents the largest landslide occurrence ever recorded in Brazil, measured by quantity. This study provides a scientific analysis of the event’s scale, spatial distribution and the associated topographic, environmental and infrastructural conditions.

🌧️ Did you know? The 2024 rains in RS, Brazil, triggered over 15,000 landslides!

Our study presents a preliminary analysis and provides a comprehensive landslide inventory, enabling other researchers to continue building insights that can help reduce disaster risks.

In 2021, historic floods in the Juruá River, Brazil’s Amazon, displaced thousands. Rainfall was 48% above average, and human-induced climate change made such events 2.5x more likely (61% attributable to human influence). Of $16.7M in damages, ~$10M was attributed to anthropic influence on climate. 🧵
