One study that identified magma hotspots underneath the Yellowstone Caldera suggests the magma is more concentrated underneath the northeast section,

A paper published in Nature Communications suggests that dissolved gases returning into cooling magma, rather than escaping from it, could help drive some of the largest volcanic eruptions on Earth. The finding challenges a long-held assumption in ...

The Hunga Tonga eruption was caught on satellite camera as a massive ash cloud blasted 20 kilometers into the atmosphere. The explosion sent a shockwave around Earth at least four times and triggered more than 200,
