Tsunami is a Japanese term for harbor wave, caused by undersea earthquakes. Rogue waves are gigantic walls of water pushing through the oceans.  Experts believe they are caused by underwater landslides that ripple the water to create a wave. Others believe rogue waves are caused by fluctuations in atmospheric pressure associated with squall lines or lines of thunderstorms. These waves appear out of nowhere as incidents of huge waves have dated as far back as 1861. Then, they were referred to as "freak waves," "monster waves," and "extreme waves." In March of 1861, off the west coast of Ireland, eagle Island lighthouse incurred the smashing of 23 window panes as a rogue wave "surmounted a 133 foot cliff." In 1900 three lighthouse operators disappeared on the Scottish coast from another wave. In the 1960s in fair weather off the coast of Spain, a large freighter was struck with a 90-foot wave. On July 3, 1992, a rogue wave swept across Daytona Beach with an 18 foot wall of water that injured 75 people and smashed hundreds of cars near the beach. North of Bermuda In 1984, a 117-foot, three masted ship sunk in less than a minute after being struck by a rogue wave resulting in numerous deaths. Cruise ships are designed to withstand hurricane force winds and storm surge as the Queen Elizabeth 2, and RMS Queen Mary reported incidents of the damaging waves. Years ago, the cruise ship, Norwegian Dawn, was blasted by a wave that was seven stories high.  The 70 foot wave occurred off the Carolina coast, after squally weather erupted on the returning voyage.  Analysis found that a low pressure system, spinning counter clockwise, encountered a high pressure system moving clockwise that created a narrow channel of strong winds and monstrous waves. The huge rogue wave injured four and flooded sixty cabins.
