Ship spies largest underwater eruption ever

Data from the seismometers, retrieved by the expedition this month, show a tightly clustered region of earthquake activity, ranging from 20 to 50 kilometers deep in Earth’s crust. Most submarine volcanoes are found along midocean ridges, where tectonic plates in Earth’s crust slowly spread apart, allowing magma from relatively shallow magma chambers to ooze up in rifts. The continuing earthquake activity, now much closer to the island, along with the possibility of a tsunami triggered by an undersea landslide from the flank of the new volcano have both alarmed the population.
