An almost overlooked fossil discovered in a Brazilian museum collection has revealed the oldest ant specimen known to science, according to new research. The prehistoric ant lived among dinosaurs 113 million years ago — several millennia before...
A magnitude 6.3 earthquake struck near the coast of Ecuador on Friday, the European Mediterranean Seismological Centre (EMSC) said, injuring at least 20 people, damaging buildings in the city of Esmeraldas and temporarily shutting down some...

How did magma oceans evolve on early Earth and Mars? Iron chemistry and primordial atmospheres offer clues

Before Earth became the blue planet, it was engulfed by a very different kind of ocean: a vast, deep magma ocean reaching down hundreds...

Clues from deep magma reservoirs could improve volcanic eruption forecasts

New research into molten rock 20km below the Earth's surface could help save lives by improving the prediction of volcanic activity. Volcanic eruptions pose significant...

How an unprecedented magma river surged beneath an Iceland town

A river of magma flowed underneath an Icelandic fishing village late last year at a rate never before recorded, scientists said Thursday, as the...

Mapping magma chambers under the Hunga volcano before and after the 2022 eruption

A small team of geologists, volcanologists and Earth scientists from the Carnegie Institution for Science, Earth and Planets Laboratory, in the U.S., the GNS...

Experimental constraints on the oxidation state of early magma on the Earth

The dark region in the lower part of the image shows crystalized bridgmanite, and the dendritic texture in the upper part indicates quenched melt....

Ancient magma reveals signs of life in zircons from ancient Earth

Zircon crystals, like a time capsule, can preserve traces of life hundreds of millions of years old in the form of biogenic carbon. Using...

Mysteries of Earth: Researchers predict how fast ancient magma ocean solidified

Early in the formation of Earth, an ocean of magma covered the planet's surface and stretched thousands of miles deep into its core. The...

Surprise magma chamber growing under Mediterranean volcano

Using a novel imaging technique for volcanoes that produces high-resolution pictures of seismic wave properties, a new study reveals a large, previously undetected body...

Hawai’i earthquake swarm caused by magma moving through ‘sills’

Magma pumping through a massive complex of flat, interconnected chambers deep beneath volcanoes in Hawai'i appears to be responsible for an unexplained swarm of...

More magma found below Yellowstone Caldera than expected

A team of researchers with members affiliated with multiple institutions in the U.S. and one in Australia reports evidence that there is much more...

Monitoring ‘frothy’ magma gases could help evade disaster

Volcanic eruptions are dangerous and difficult to predict. A team at the University of Tokyo has found that the ratio of atoms in specific...
