Silent Magma Surge Lifted Azorean Island 2.5 Inches, Then Stopped Abruptly Below the Surface

Silent Magma Surge Lifted Azorean Island 2.5 Inches, Then Stopped Abruptly Below the Surface

Learn how a series of earthquakes on an Atlantic island revealed magma brew merely 1 mile under the surface and how underground faults evaded the eruption.

Atlantic Island Narrowly Escaped ‘Stealthy’ Eruption

Thousands of earthquakes affecting Portugal's São Jorge Island in the Azores in March 2022 were triggered by a vast sheet of magma (molten rock) rising from more than 20km below Earth's surface and stalling just 1.6km beneath the island, finds a new study led by UCL researchers.
