Scientists Uncover Something Terrifying Beneath the Puerto Rico Trench—And It’s Alarming

When people think of trenches, the first word that comes to mind is usually Mariana. But the Pacific is not the only ocean with a dangerous, mysterious fissure lying on its floor. The spotlight has recently turned to the Puerto Rico Trench and its unsettling activity, but despite the attention, it is still one of many deep-sea trenches around the globe that remain largely unexplored. These vast, underwater chasms are some of the least understood environments on Earth, hiding tectonic secrets, extreme ecosystems, unexplained phenomena, and in some cases, silent warnings. What scientists recently discovered beneath the Puerto Rico Trench is really terrifying, but most importantly, bad for humankind as a whole.
