An expert on TV said the weight of water at 13 miles deep applied to it was as much as weight of the Empire State building.

“The deep-sea water pressure that appears to have crushed the 22-foot craft would have been roughly equivalent in weight to the 10,000-ton, wrought-iron Eiffel Tower….”
That’s 20 million pounds of pressure!
