When tens of thousands of earthquakes shook Santorini, the cause wasn’t just shifting tectonic plates—it was rising magma. Scientists tracked about 300 million cubic meters of molten rock pushing up ...

Volcanoes erupt because hot, melted rock from deep inside the Earth finds a way to reach the surface. This melted rock is called magma, and it forms when parts of the Earth’s mantle become so hot that ...

Scientists have uncovered a long-missing piece of the volcanic puzzle: rising magma doesn’t just form explosive gas bubbles when pressure drops—it can do so simply by being sheared and “kneaded” ...

POPOCATÉPETL VOLCANO, Mexico (AP) — In the predawn darkness, a team of scientists climbs the slope of Mexico’s Popocatépetl volcano, one of the world’s most active and whose eruption could affect ...

The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped ...

Japan is one of the most volcanically active nations. Its world-leading research on volcanic disasters has led to new ...
