One of the worst disasters I have ever seen involving a landslide occurred in both Nepal & China earlier today. This landslide occurred high on a mountain, descended more than 3,000 feet, before transitioning into one of Asia's worst flash floods of the 21st century. High rises and bridges were swept away, along with many smaller structures. Today's video will analyze what happened through the knowledge and analysis of a geologist. This video's thumbnail image displays a much smaller flood from Nepal in a prior year (not 2026). Approximate GPS coordinates of the landslide: 28.273, 85.517 If you would like to support this channel, consider using one of the following links: (Patreon: http://patreon.com/geologyhub) (YouTube membership: https://www.youtube.com/channel/UCYeGh5VML5XPr5jYnzh3J6g/join) (Gemstone & Mineral Etsy store: http://prospectingarizona.etsy.com) (GeologyHub Merch Etsy store: http://geologyhub.etsy.com) Google Earth imagery used in this video: ©Google & Data Providers This video is protected under "fair use".
