Volcanoes are Earth’s geologic architects. They’ve created more than 80 percent of our planet’s surface, laying the foundation that has allowed life to thrive. Their explosive force crafts mountains ...

Some volcanoes, such as the Cascade volcanoes up in Washington and Oregon, are of the type called a stratovolcano. These steep volcanoes sometimes erupt explosively and other times have calmer lava ...

How did young volcanoes on Mars form? This is what a recent study published in the journal Geology hopes to address as a team of scientists investigated the complex geological processes responsible ...

Along 1,100 kilometers, from Mexico to Costa Rica, lies the Central American volcanic arc, where the variety of magma types make for a geological paradise. By Pablo Fonseca Q. / Knowable Magazine ...

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 ...

Located in Sicily, Mount Etna is Europe’s most active volcano. Yet its origin remains largely enigmatic, as no existing geological model fully explains how it formed. In a new study, scientists from ...

Young Mars would have been a staggering place to explore. The Red Planet was covered in flowing rivers of both water and lava. At the time, a series of four volcanoes — Olympus Mons and the three ...

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 ...
