IT OUTLINES THE COOPERATION BETWEEN COUNTRIES FOR SCIENTIFIC RESEARCH
The shockwave from an undersea earthquake causes 'ripples' in the ocean which are very large swells. When the bottom of the swell touches land, it must build up higher to maintain it's size.

More water is drawn from in front of the swell than behind due to the movement of the swell.
