Wider coverage of satellite data better detects magma supply to volcanoes

Using satellite imaging, researchers for the first time identified a major magma supply into a reservoir extending almost two miles from the crater of a volcano in Nicaragua.

Subterranean Serendipity: Scientists stumble upon a new way to sample magma

Scientists have never directly observed magma beneath the Earth’s surface. But thanks to the discovery of easily accessible magma chambers, it may now be possible, report scientists at the 2017 American Geophysical Union Fall Meeting in New Orleans.

Moon’s Crust Underwent Resurfacing after Forming from Magma Ocean

A research team took to the lab to recreate the magmatic melt that once formed the lunar surface and uncovered new insights on how the modern moonscape came to be. Their study found found that one of the great mysteries of the lunar body’s formation – how it could develop a crust composed largely of just one mineral – cannot be explained by the initial crust formation and must have been the result of some secondary event.

New equation describes how Earth cooled from magma into rock

A new mathematical model shows strong evidence that when Earth formed, it cooled from the inside out rather that bottom up. Scientists who presented the research at the 2016 American Geophysical Union Fall Meeting said the new model helps scientists better understand Earth’s early history—how it cooled and became the rocky planet it is today.

3D images of magma below Mono Craters

A new conceptual model of the magma system below Mono Lake and Mono Craters in eastern California gives scientists a more detailed understanding of volcanic processes at depth and a better model for forecasting volcanic unrest. The accuracy and high resolution of the new three-dimensional images of the magma chambers and volcanic “plumbing” below Mono Basin give scientists a better understanding of their size, shape and where the next eruption might occur.
