Underwater volcanoes are powerful geological forces shaping our planet and oceans. These hidden giants form through tectonic ...

The tiny Juan de Fuca plate is largely responsible for the volcanoes that dot the Pacific Northwest of the United States. The plates make up Earth's outer shell, called the lithosphere. (This includes ...

The Earth's outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The Christian Science Church, and we’ve always been transparent about that. The Church publishes the Monitor ...

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 ...

For the first time in history, scientists have observed the rupture of a tectonic plate in a subduction zone in real time.

The Earth's mantle might not always move along in lockstep with the overlying tectonic crust—as set out in science textbooks for decades—but may instead behave differently. This is the conclusion of ...

Scientists have recently discovered a new way that volcanoes are forming – deep below the paradise island of Bermuda. We all know from middle school Earth Science that the shifting of tectonic plates ...

Meghan Bartels is a science journalist based in New York City who covers the science happening on the surface of Earth. She can be reached via email. Let's get one thing out of the way: The ...

Plate tectonics, responsible for deadly earthquakes and volcanoes around the globe, may also be a key factor in the success of life as we know it on the third planet, a new study suggests. As the ...

Martian meteorites are mostly volcanic in origin, but how they are related to one another and where they come from on Mars have been enduring scientific puzzles. These meteorites can be found in the ...

It comes as no shock that a potentially new type of volcanic lightning had long eluded scientists: The bolts can be as short as about 3 feet (1 meter) long and last just a few milliseconds. But ...
