Titanic Shipwreck

Very few shipwrecks are famous catastrophes like the wrecks of the Titanic, Britannic, Lusitania or Estonia. There are also thousands of wrecks that were not lost at sea but have been abandoned or sunk. These are typically smaller vessels such as fishing vessels. These vessels can provide an interesting recreational dive but are usually of little interest to historians. They may pose a hazard to navigation and may be removed by port authorities. These vessels are sometimes referred to as abandoned or derelicts.. There are more than 3 million wrecks on the ocean floor, the United Nations estimates.
Causes
The loss of a ship could be due to poor design, improperly stowed cargo, navigation errors and other human errors, leading to collisions (with another ship, rocks, an iceberg, etc.) or running aground; bad weather; warfare; piracy, mutiny, or sabotage; fire.
