The largest waves ever recorded in history

A wave is formed when the wind hits the surface of the water, producing a drag effect.

This thrust, at first, creates small disturbances called “capillary waves” that start out a few mils high, up to a couple of centimeters or 1 inch.

When the friction effect intensifies, the initial small ripples become “gravity waves”. The air moves the liquid and the force of gravity attempts to pull it back into place, producing the rippling motion.
