| - False: This Caribbean Sea tsunami video is AI-generated
A dramatic video of what appears to be a tsunami was posted on X on Feb. 10. In the video, a towering wave under thick clouds is seen crashing against the beach with cottages and villas near the water. A siren can be heard in the video.
The post reads, “🚨 M 7.6 Earthquake – 209 km SSW of George Town, Cayman Islands 🌊⚠️ Tsunami Warning Issued! Stay Alert!” It was shared after a 7.6-magnitude earthquake struck the Caribbean Sea on Feb. 8, garnering over 2,200 likes and close to 600 shares.
The U.S. Geological Survey reported the epicentre was 32 km north of Honduras and 209 km southwest of the Cayman Islands, according to BBC.
The video was also shared on TikTok (here and here) with similar claims about the earthquake in the Caribbean. Comments on the platform indicated some users believed the tsunami image was real.
However, this video is made with Sora, OpenAI’s generative AI model to create video content. It is not real. There had been no reports of tsunami in the region, as far as Annie Lab can tell.
An animated watermark of Sora is actually visible at the bottom right corner of the shared clip.
We also discovered that the same video can be found on YouTube and TikTok, claiming to show a tsunami in Indonesia and California.
Through an image search, we found a TikTok account posting AI-generated content about natural disasters, including the video in question. All of the videos are labeled as AI-generated and carry the logo of OpenAI.
OpenAI incorporates the Coalition for Content Provenance and Authenticity (C2PA) metadata in the images and videos created by its AI models. The metadata, which is often referred to as Content Credentials, shows the content’s origin, creation process, and any subsequent modifications.
TikTok preserves the Content Credential attached to the content. When Annie Lab ran the video in question through Content Credentials’ Verify tool, it detected the metadata issued by OpenAI.
The information tells that the video was created with Sora at 2:25 p.m. GMT+8 on Jan. 28, and uploaded to TikTok in less than five minutes. This suggests that the account “@pixel.machine” is likely the creator of the video.
The account holder sometimes uses hashtags in Portuguese and includes words like “IA” and “vulcao,” which means AI and volcano.
Although the recent quake was the largest in the region since 2021, no major tsunami was reported, according to German news outlet DW.
Meanwhile, a wave of 0.04 meters, or four centimeters, was observed off the coast of Isla Mujeres, Mexico, the U.S. National Tsunami Warning Center said.
The Center’s website shows that its tsunami warning in affected places such as Puerto Rico, Haiti, and the Cayman Islands was lifted within hours.
