1. Pakistan: Torrential Storms and Landslides Paralyze Shangla District
Over the last 24 hours, extreme weather in northwest Pakistan has escalated into a severe crisis. Continuous heavy rainfall has triggered multiple landslides across the Shangla district in Khyber Pakhtunkhwa.
- The Event: Intense downpours blocked the main Alpuri-Besham road and several critical link roads, isolating the valley.
- Impact: The slides, combined with lightning strikes, destroyed over a dozen power lines and three major transmission poles, plunging the entire district into darkness. Communication networks, including mobile services, remain severely disrupted.
- Risk Context: Authorities are monitoring rising water levels in rivers and rain-fed channels, which pose an imminent threat to low-lying communities as moisture continues to destabilize steep Himalayan slopes.

2. Ethiopia: Fatal Landslides and Flash Floods Kill 30 in Gamo Zone
Unseasonal and continuous rainfall between March 9 and early March 11 has resulted in a humanitarian disaster in the highland areas of the South Ethiopia Regional State.
- The Event: Landslides struck several kebeles (neighborhoods) across three woredas, with the most devastating impact in Bonke and Gacho Baba.
- Impact: At least 30 people have died. In one instance, a landslide completely buried a home in Yela Kebele, killing a mother and her two children.
- Risk Reduction: Debris from the slides has blocked public transport routes, complicating rescue efforts. Regional authorities warn that the ongoing Belg season rains are likely to trigger further slides in the mountainous zones of Wolayta, Gedeo, and Gofa.

3. Global Science Update: Study Links Unplanned Urbanization to Brazil’s Landslide Toll
A new rapid attribution analysis released on March 11–12 provides critical insights into the late-February disaster in Juiz de Fora, Brazil, where 72 people were killed.
- Key Finding: While climate change is making rainfall more intense (projected 7% increase with future warming), the primary driver of the high death toll was social vulnerability and unplanned urban expansion.
- The Data: In Juiz de Fora, roughly 130,000 people live in high-risk zones. The study highlights that the local return period for the February rainfall was several hundred years, yet early warnings were hindered by topographical constraints (siren effectiveness) and lack of evacuation options.
- Strategic Insight: The report emphasizes that “warnings alone are insufficient” and must be paired with land-use reform and physical risk education to be effective.

Graphics & Visual Assets
- Infographic Suggestion: Create a chart showing the “Hazard vs. Vulnerability” relationship found in the Brazil study—demonstrating that even moderate hazards can lead to disasters when urbanization is unplanned.
- Live Monitoring: You can use the USGS Landslide Inventory Map for royalty-free base maps to illustrate global “hotspots” currently under high precipitation alerts.
- Technical Diagram: A schematic of Pore-Water Pressure ($\mu$) versus Effective Stress ($\sigma’$) would be an excellent “Engineer’s Corner” addition to explain why the Ethiopian highlands are failing now.
