A new study published in the Proceedings of the National Academy of Sciences (PNAS) provides scientists with a powerful new tool for monitoring and predicting tectonic activity deep beneath the seafloor at mid-ocean ridges—vast underwater mountain chains that form where Earth’s tectonic plates diverge.
A new study published in the Proceedings of the National Academy of Sciences (PNAS) provides scientists with a powerful new tool for monitoring and predicting tectonic activity deep beneath the seafloor at mid-ocean ridges—vast underwater mountain chains that form where Earth’s tectonic plates diverge.
The study, titled “Hydrothermal vent temperatures track magmatic inflation and forecast eruptions at the East Pacific Rise, 9°50'N,” reveals that fluctuations in the temperature of fluids flowing from hydrothermal vents occurring over minutes to years indicate the effects of magmatic and tectonic processes that occur miles beneath the seafloor. The research offers the first evidence that these subtle but detectable temperature changes could offer the means to predict seafloor volcanic eruptions.
Led by Thibaut Barreyre of the French National Centre for Scientific Research (CNRS) and University of Brest, with collaborators from Woods Hole Oceanographic Institution (WHOI), Lehigh University, and Scripps Institution of Oceanography, the study presents a 35-year time-series of temperature measurements from five hydrothermal vents along the East Pacific Rise, one of the most active segments and well-studied of the global mid-ocean ridge system.
