NOAA explains that seawater descends through cracks in oceanic crust, is heated by magma, and rises again through hydrothermal vents. Vent water may exceed 400°C, while the enormous pressure of the deep ocean prevents it from boiling. This directly supports the physical fact that very hot water emerges from the ocean floor.

Woods Hole likewise reports that hydrothermal-vent fluids can reach about 400°C and that most vents occur along mid-ocean ridges. Scientists first discovered deep-sea hydrothermal vents near the Galápagos in 1977. That discovery date supports the modern scientific history, though surface hot springs and volcanic heating were known much earlier.

Quran 81:6 appears in a passage describing the events of the Day of Judgment. Modern translations render سُجِّرَتْ as the seas being ‘set on fire,’ while classical explanations also record meanings such as filled, overflowed, dried up, or kindled. Hydrothermal vents are real scientific evidence of intense heating beneath parts of the seafloor, but identifying them as the intended meaning of this verse is a modern reflection, not a conclusion established by geology or the classical tafsir.
