The European Space Agency satellite looks out for conditions that create freak waves (including the Cross sea patterns as per the image), usually caused by two distant storm. Cross sea conditions are most common in the South Pacific, which might explain the greates number of ship losses in the past three hundred years.
Approximately once a year or so they plot a massive disturbance that creates a freak wave, and every ten or so years there will be a monster version, which can be upwards of 25metres in height. Predictions are that these are increasing in rate and intensity.
The world’s tallest ocean waves are generated south of Iceland. From there, these giants roll into the Norwegian and North Seas.
