Undersea Volcanism Triggered By Outpouring Magma




A graduate student, Yen Joe Tan, from Columbia University's Lamont-Doherty Earth Observatory has recently analyzed a volcanic eruption at a mid-ocean ridge under the Pacific. As per the analysis, the scientists have observed that upwelling magma is responsible for the volcanic eruption. Additionally, the magma forces a critical pressure on the volcanoes and forces its way up, allowing the lava to spill out.

While putting an example of an eruption that was happened in the East Pacific Rise, some 700 miles off Mexico, the scientists explained the process of volcanic eruption. The scientists stated that the process of eruption happens through several changes in the basic mechanism of tectonic plates.

Moreover, the mid-ocean ridges are mountain chains that run endlessly for more than 40,000 miles along the planet's seafloors, stated the scientists. From centre the volcanoes discharge lava that forces the seafloor out in opposite ways from the ridges toward the continents. Additionally, mostly the leading edge of the seafloor dives beneath the land and is subsumed back into the deep earth.
