On June 7, 1692, at 11:43 AM, a 7.5 magnitude earthquake and tsunami ripped through Jamaica, destroying Port Royal, killing and injuring thousands. 
Port Royal was a haven for pirates and privateers, like Calico Jack, Captain Morgan, Anne Bonny, and Blackbeard, slavers and every vice driven crime known.

Port Royal, Jamaica, commonly referred to as “the wickedest city on earth” conjures images of marauding pirates, daring naval conquests, looting, riches, destruction and devastation. It boats an intriguing and turbulent history as it rapidly grew to become the most important trading post in the New World. At the height of its glittering wealth, on June 7, 1692, Port Royal was consumed by an earthquake and two thirds of the town sank into the sea. A series of fires and hurricanes followed and the town was never restored to its former glory. Port Royal lived out its days as a British naval station and remains as a small fishing village today.

When the dust settled, 33 acres of Port Royal sunk into the Caribbean Sea, an estimated 1,500 and 2,000 people dead and another 3000 seriously injured, out of a population of 6,500. Compounding the disaster was the outbreak of looting that saw homes, warehouses and the dead stripped of everything.
