Jonas Mureika, a professor of physics at Loyola Marymount University, tells The Independent that calling the implosion “catastrophic” is referring to the intensity and speed of what took place.“The pressure at that depth (3.8 km) is incredibly high, about 400 times atmospheric pressure. That’s 6,000 pounds per square inch acting on the submarine – atmospheric pressure is roughly 15 pounds per square inch,” he noted in an email.
