The Sewol leaves port in Incheon at around 9pm with 475 people and 150 vehicles on board, heading for Jeju Island.
April 16, 8.55am
First contact between vessel and land is made, with officer telling Jeju Vessel Traffic Services Centre (VTS) "our ship is in danger".
Survivors say passengers were told to remain in cabins.
April 16, 9am

April 17
Text messages from people on board the ferry reveal passengers were ordered to remain in their seats and cabins as ship began listing.
Crew member Oh Yong-Seok reveals the captain waited 30 minutes before ordering the evacuation as officers tried to stabilise the vessel. By that time, the crew were unable to reach passengers because the ship was titled at such an acute angle.
April 18
Investigators reveal the ship's captain, Lee Joon-Seok, was not at the helm when the Sewol began to list. They are also examining why the ship's third mate ordered an abrupt turn around three hours before the vessel was due to arrive at Jeju Island.
Mr Lee, along with two more of the ship's crew, are arrested.
Vice-principal of Danwon High School, Kang Min-Kyu, is found dead on Jindo island. In a note found in his wallet, he described his rescue as "too painful while 200 remain unaccounted for".

Mr Lee issues a public apology for causing a "disturbance" and says he delayed the evacuation of the ferry because he thought the sea water was too cold.
Investigators reveal the third mate was steering the ship in difficult waters for the first time and in foggy conditions.
Divers trying to gain access to the ferry describe seeing bodies through its windows as the death toll officially climbs above 30.
April 20
