Why might the atlantic ocean have appeared to shrink in the late 1930

The time between 1933 and 1934, the Atlantic ocean experienced its highest temperature in history... This phenomenon cause shrinking of the water of the Atlantic ocean. The atlantic ocean is getting bigger while the pacific ocean is shrinking. Although, the research is out there, some might not be correct. The Ocean is more than 60% of the earth, and we haven't even gotten close to finding what lies beneath, and some people believe that the Atlantic ocean appeared to of shrink, because of an earthquake that made a very large hole in the ocean. The water fills any space it can find, with all liquids, and The hole must of sucked in all of that water, causing the ocean to shrink. There is no proof of this, but some people have gone out and allegedly found proof of this theory.
