South and Southeast Asia Monsoon Floods (June-September 2025)

The 2025 monsoon floods were catastrophic across Bangladesh, India, Nepal, Pakistan, and Myanmar, affecting over 20 million people and killing at least 800. Agricultural losses alone exceeded $10 billion, with the Indian state of Assam enduring its worst floods in 30 years as 2.5 million people were evacuated along the Brahmaputra River. This disaster's affected population is 110 times larger than that of #2, the Myanmar-Thailand Earthquake, yet the death toll remains lower due to earlier warnings and evacuations, which reduced fatalities by 40% compared to similar events in 2024.
