A video of strong ocean waves crossing the seawall and washing away boats, cars, and small structures is being shared on social media. The video, which shows a lot of damage and destruction, is being shared with the claim that it showed the effect of China's Three Gorges Dam gates being opened.
However, we found that the clip is old. The 2011 video shows tsunami waves hitting the Iwate prefecture on Japan's eastern coast.
WHAT WE FOUND
Using InVID, a Google Chrome extension for video verification, we broke the video down into multiple frames and ran reverse image searches on them.
The results led us to a YouTube video uploaded by user 'Jon Lu', which carried the visuals and identified the incident as 'The 2011 Tsunami in Japan'.
Using '2011 Japan Tsunami' as additional keywords to the reverse image search, we looked for video reports about the devastating disaster. We found a report by ABC News dated 14 March, 2011. The report carries a logo on the top-right, attributing the video to ANN (All-Nippon News Network).
Both videos of the incident have the same visuals. For instance, this vessel can be seen toppling near a bridge in the claim as well as ABC News' report.
We looked further and found the video uploaded to 'ANNnewsCH' early last year in 2020, titled 'Tsunami, Great East Japan Earthquake - Miyako city, Iwate Pref, Japan [11 Mar 2011]'.
Clearly, the video does not show the effect of the Three Gorges Dam gates being opened in China. It is an old video from Japan that shows tsunami waves in Miyako city in Iwate Prefecture.
