South korea sewol ferry emerges from the water 3 years after sinking

I think there may be some misinformation here.

The Sewol ferry did not emerge from the water 3 years after sinking. In fact, the ferry sank on April 16, 2014, and it has been lying on the seafloor at a depth of about 40 meters (131 feet) off the coast of South Korea's Baengnyeong Island ever since.

The Sewol ferry disaster was one of the deadliest maritime accidents in South Korean history, resulting in the loss of 304 lives, with only 172 survivors. The cause of the sinking was attributed to a combination of factors, including excessive cargo, poor design, and inadequate safety measures.

Since the sinking, the wreckage has been the subject of several salvage and recovery efforts, including a 2017 operation to remove the ferry's fuel and other hazardous materials. However, the ferry itself has not been recovered or raised from the seafloor.

It's possible that you may be thinking of a different incident or a fictional event. If you have any further information or clarification, I'd be happy to help!
