WebMay 10, 2024 · Vents – openings through which lava flows – located a distance away from, and at a much lower elevation than, the volcano’s summit. “Sometimes, volcanoes erupt at the summit, but an eruption can also occur when lava breaks through vents much lower down the volcano,” said JPL’s Paul Lundgren, co-author of the study. WebDec 30, 2024 · As explained in Section 1, research shows that volcanism in this area is being supercharged by melting of the base of the Colorado Plateau by hot asthenospheric rock. That magma then flows out to find weak zones like the active faults in Parashant, where the magma can rise and erupt.
