Today, the entire globe is broken up into tectonic plates that are shifting past each other, causing the continents to drift slowly but steadily. But this has not always been the case.

The earliest evidence for plate tectonic features which could…

The heights of La Soufrière de Guadeloupe volcano can be hellish, sweltering at more than 48 degrees Celsius (120 degrees Fahrenheit) and swathed in billows of acidic gas.

Researchers would like to monitor gas and steam eruptions at its summit,…

Geologists from Florida State University’s Department of Earth, Ocean and Atmospheric Science have discovered how carbon-rich molten rock in the Earth’s upper mantle might affect the movement of seismic waves.

The new research was coauthored…

Ancient sediment found in a central Texas cave appears to solve the mystery of why the Earth cooled suddenly about 13,000 years ago, according to a research study co-authored by a Texas A&M University professor.

Some researchers believed the event…

An international team of volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes which reliably produce small basaltic lava eruptions hide chemically diverse magmas in their underground plumbing systems –…

The activity of the solid Earth – for example, volcanoes in Java, earthquakes in Japan, etc – is well understood within the context of the ~50-year-old theory of plate tectonics.

This theory posits that Earth’s outer shell (Earth’s…

Research by the University of Liverpool has revealed that strange behaviour of the magnetic field in the South Atlantic region existed as far back as eight to 11 million years ago, suggesting that today’s South Atlantic Anomaly is a recurring…

A rock core from Petrified Forest National Park, Arizona, has given scientists a powerful new tool to understand how catastrophic events shaped Earth’s ecosystems before the rise of the dinosaurs.

The quarter-mile core is from an important part…

Plato, the Greek philosopher who lived in the 5th century B.C.E., believed that the universe was made of five types of matter: earth, air, fire, water, and cosmos. Each was described with a particular geometry, a platonic shape. For earth, that…

An ancient European volcanic region may pose both a greater long-term volcanic risk and seismic risk to northwestern Europe than scientists had realized, geophysicists report in a study in the Geophysical Journal International.

The scientists are…
