What triggered the catastrophic flood on the Nepal-Tibet border?

Torrential floods in Nepal and Tibet have killed at least twenty-two people. Hundreds of travelers, including many Indians, are currently reported missing after the disaster. An earthquake is suspected to have triggered an ice-rock avalanche causing the devastating floods. Rescue efforts are underway, but challenges remain due to flood sediment and difficult terrain. Authorities have warned of potential secondary floods and issued alerts in bordering Indian states.
