The 25-26 September 2026 cluster of landslides in Tanintharyi Region, Myanmar
Eos · By Dave Petley ·
The Brief
- A low pressure system over the North Andaman Sea on 25-26 September 2026 generated strong monsoon conditions in western Myanmar.
- The system triggered hundreds of landslides in the west of Myanmar in September, according to Eos.
- The Eos author's own calculation puts the toll at 12 fatal landslides killing 40 people.
Why it matters
It shows how a single monsoon low pressure system can set off landslides across a wide area, which matters for hazard forecasting and risk planning in similar terrain.
Who’s affected
- Residents of Tanintharyi Region, Myanmar
