Query: Around 1990 it became obvious the local tide-gauge did not agree - there was no evidence of 'sinking.'

Sinking of MV Sewol <=SEP=> The sinking of Sewol , also referred to as the Sewol Ferry Disaster , occurred on the morning of 16 April 2014 , en route from Incheon to Jeju in South Korea . The ferry capsized while carrying 476 people , mostly secondary school students from Danwon High School ( Ansan City ) . The 6,825-ton vessel sent a distress signal from about 2.7 km north off Byeongpungdo at 08:58 Korea Standard Time ( 23:58 UTC , 15 April 2014 ) . In total , 304 passengers and crew members died in the disaster . Of the approximately 172 survivors , more than half were rescued by fishing boats and other commercial vessels that arrived at the scene approximately 40 minutes after the South Korean coast guard .   The sinking of Sewol resulted in widespread social and political reaction within South Korea . Many criticized the actions of the captain and most of the crew . More criticized the ferry operator and the regulators who oversaw its operations . Additional criticism was directed at the South Korean government and media for its disaster response ( including the poor showing of the then Korean coastguard ) and attempts to downplay government culpability .   On 15 May 2014 , the captain and three crew members were charged with murder , while the other 11 members of the crew were indicted for abandoning the ship . An arrest warrant was also issued for Yoo Byung-eun , the owner of Chonghaejin Marine , which operated Sewol , but he could not be found despite a nationwide manhunt . On 22 July 2014 , police revealed that they had established that a dead man found in a field 415 kilometres south of Seoul was Yoo . Foul play was ruled out , but police say they have yet to establish the cause of Yoo 's death .   On the first anniversary of the disaster , as part of commemorations for the victims of the sinking of Sewol , 4,475 people held electronic candles to form the shape of the ferry in an attempt to set a Guinness World Record for the largest torchlight image .

Sinking of the RMS Titanic <=SEP=> The sinking of the RMS Titanic occurred on the night of 14 April through to the morning of 15 April 1912 in the North Atlantic Ocean , four days into the ship 's maiden voyage from Southampton to New York City . The largest passenger liner in service at the time , Titanic had an estimated 2,224 people on board when she struck an iceberg at around 23:40 ( ship 's time ) on Sunday , 14 April 1912 . Her sinking two hours and forty minutes later at 02:20 ( 05:18 GMT ) on Monday , 15 April resulted in the deaths of more than 1,500 people , which made it one of the deadliest peacetime maritime disasters in history .   Titanic received six warnings of sea ice on 14 April but was travelling near her maximum speed when her lookouts sighted the iceberg . Unable to turn quickly enough , the ship suffered a glancing blow that buckled her starboard ( right ) side and opened five of her sixteen compartments to the sea . Titanic had been designed to stay afloat with four of her forward compartments flooded but no more , and the crew soon realised that the ship would sink . They used distress flares and radio ( wireless ) messages to attract help as the passengers were put into lifeboats . In accordance with existing practice , Titanic 's lifeboat system was designed to ferry passengers to nearby rescue vessels , not to hold everyone on board simultaneously ; therefore with the ship sinking rapidly and help still hours away , there was no safe refuge for many of the passengers and crew . Compounding this , poor management of the evacuation meant many boats were launched before they were completely full .   Thus , when Titanic sank , over a thousand passengers and crew were still on board . Almost all those who jumped or fell into the water drowned within minutes due to the effects of hypothermia . arrived on the scene about an hour and a half after the sinking and rescued the last of the survivors by 09:15 on 15 April , some nine and a half hours after the collision . The disaster caused widespread outrage over the lack of lifeboats , lax regulations , and the unequal treatment of the three passenger classes during the evacuation . Subsequent inquiries recommended sweeping changes to maritime regulations , leading to the establishment in 1914 of the International Convention for the Safety of Life at Sea ( SOLAS ) , which still governs maritime safety today .

Sinking of the RMS Lusitania <=SEP=> The sinking of the Cunard ocean liner RMS Lusitania occurred on Friday , 7 May 1915 during the First World War , as Germany waged submarine warfare against the United Kingdom who had implemented a naval blockade of Germany . The ship was identified and torpedoed by the German U-boat and sank in 18 minutes . The vessel went down 11 mi off the Old Head of Kinsale , Ireland , killing 1,198 and leaving 761 survivors . The sinking turned public opinion in many countries against Germany , contributed to the American entry into World War I and became an iconic symbol in military recruiting campaigns of why the war was being fought .   Lusitania had the misfortune to fall victim to torpedo attack relatively early in the First World War , before tactics for evading submarines were properly implemented or understood . The contemporary investigations in both the UK and the United States into the precise causes of the ship 's loss were obstructed by the needs of wartime secrecy and a propaganda campaign to ensure all blame fell upon Germany . Argument over whether the ship was a legitimate military target raged back and forth throughout the war as both sides made misleading claims about the ship . Before Lusitania sailed , the German embassy had placed warnings in American newspapers that the ship would be targeted as it was carrying war munitions . At the time she was sunk , she was carrying over 4 million rounds of small-arms ammunition ( .303 caliber ) , almost 5,000 shrapnel shell casings ( for a total of some fifty tons ) , and 3,240 brass percussion fuses , in addition to 1,266 passengers and a crew of 696 . Several attempts have been made over the years since the sinking to dive to the wreck seeking information about precisely how the ship sank , and argument continues to the present day .
