Here is What Caused the Apocalyptic Nepal Floods that Resulted in Hundreds of Deaths and Over a Thousand Disappearances, Including Dozens of Americans * The Gateway Pundit * by Cullen Linebarger

It is now known what caused the historic Nepal floods on Wednesday that resulted in hundreds of people dying and thousands more going missing, including dozens of Americans.

As the BBC reported, the US Geological Survey revealed the flash floods were triggered by a massive high altitude glacial collapse in a mountainous area near the Nepal-Tibet border.

This triggered seismic activity and catastrophic downstream impacts along the Trishuli River, while floodwaters spread across several regions in Nepal.

CNN notes that major swaths of ice up in the Himalayas are melting, and rocky mountainsides are becoming less solid and more fluid.

This has made Nepal more vulnerable to disasters like this.

The United States Geological Survey also reported recording a 4.4-magnitude quake around the time the security footage was taken at the Nepal-Tibet border.

As The Gateway Pundit previously reported, several videos went viral showing a depiction of the Biblical flood in the landlocked nation.

As one can see in the videos, the catastrophic flash flooding materializes as a massive surge of water descends from the mountains and destroys a border crossing building, as dozens of terrified people can be seen running for their lives.

At last count, more than 350 souls have perished in the floods. More than 1,300 people also remain missing or unaccounted for across the region.

This number includes at least 65 American citizens.

U.S. Secretary of State Marco Rubio has said America “stands ready to support the Government of Nepal with needed humanitarian assistance.”

We express our solidarity and are united in prayer for the Nepali people following the devastating floods. @StateDept stands ready to support the Government of Nepal with needed humanitarian assistance.
