The last three hours of the Titanic

On the night of April 14, 1912, four days after leaving Southampton port in England, the Titanic suffered a terrible disaster. A navigator on board shouted: "Iceberg, front right". (Graphic: BBC)

23h40 on the same day, the largest ship in the world at that time bumped up with a giant iceberg. Thomas Andrews, the ship's architect, came directly to inspect the damage and concluded that the ship was being infiltrated by sea water from a puncture after a collision. Titanic, the ship once thought to be unable to sink, was beginning to sink. (Graphic: National Geographic)

0:30 on April 15, 1912, Captain Edward J. Smith ordered the rescue ships to be lowered to evacuate passengers as well as crew. 10 minutes after the order was issued, the first rescue ship was released into the sea. Children and women are prioritized to evacuate first. Although the lifeboats on the Titanic could carry up to 1,000 people, many small ships were dropped into the sea, containing only about half the number of people allowed. (Graphic: BBC)

At 2:10 pm, electricity on the Titanic is off. At this point, the bow of the ship has sunk below the sea surface, while the stern part has gradually risen. About 18/20 rescue ships were then released into the sea. (Graphic: BBC)

Only 7 minutes later, the 52,310-ton ship began to break in half because the hull could not withstand the tension in the middle of the third chimney and the fourth chimney. (Graphic: BBC)

2h19, after being completely removed from the tail, the Titanic's bow began to sink. The stern part still floats on the water surface but also begins to sink because the water has spilled into the engine compartment. (Graphic: BBC)

The tail of the Titanic begins to wish straight to the seabed at around 2:20. Meanwhile, the bow tip reaches the sea floor at 2h22 after dropping at a speed of about 40 to 64km / hour. The impact was strong on the sea floor, causing the crust of the Titanic's bow to deform. (Graphic: BBC)

The tail of Titanic plunges into the seabed even faster, with a speed of about 96km / hour. It reached the bottom of the sea at about 2h24 and was in a position about 600m away from the bow. (Graphic: BBC)

The map depicts the fateful journey of the Titanic, since its departure from Southampton on April 10, 1912, when it crashed in the Pacific Northwest on April 14, 1912. The Titanic disaster killed 1,514 people. (Graphics: Wikipedia)
