Shortly before 9am – The ferry makes a sharp right turn while navigating a group of islets off the southern coast.
Experts say the radical turn could have dislodged the ship’s heavy cargo, including more than 150 vehicles, causing the vessel to capsize.
At the time, the ship was steered by the helmsman under the supervision of the female third officer who had never navigated that particular stretch of water before.
9am – The vessel makes its first distress call.
Audio reveals the crew panicked as they deliberated over whether to evacuate passengers.
9.11am – Ferry lists to a 43-degree angle, making it difficult for passengers to move.
9.30am – The vessel has listed to a 60-degree angle. Passengers have been ordered not to move. Rescue ships are yet to arrive.
9.40am – 11am – Passengers are ordered to abandon ship, but many are unable to escape as the vessel is tilted at an acute angle.
Within two hours of the initial distess call, the ferry inverts completely and sinks 20 kilometres off the southern island of Byungpoong.
Some 174 passengers are rescued. Many survivors are picked up by small commercial vessels that got to the scene before a flotilla of coastguard and navy ships arrived, backed by more than a dozen helicopters.
Rescue teams, including almost 200 divers, work under floodlights throughout the night to reach the other passengers.
