Grain size of rocks in Earth’s mantle affects tectonics

The planet is shaped by forces deep within its interior. These push the plates of the Earth's crust against each other, causing mountains and...

NASA’s ECOSTRESS sees Las Vegas streets turn up the heat

An instrument on the space station documented how built and natural surfaces responded to record heat in Las Vegas. On June 10, Las Vegas reached...

Earliest record of wildfires provides insights into Earth’s past vegetation and oxygen levels

While wildfires over recent years have raged across much of the western United States and pose significant hazards to wildlife and local populations, wildfires...

Potential mechanism for olivine to carry boron into the Earth’s deep mantle

Olivine is an important component of Earth's upper mantle. The effect of boron on the properties of olivine has been previously ignored since boron...

Puzzling features deep in Earth’s interior illuminated

New research led by the University of Cambridge is the first to take a detailed image of an unusual pocket of rock at the...

The Earth moves far under our feet: A new study shows that the inner core oscillates

USC scientists have found evidence that the Earth's inner core oscillates, contradicting previously accepted models that suggested it consistently rotates at a faster rate...

Yellowstone’s history of hydrothermal explosions over the past 14,000 years

While much of public attention on Yellowstone focuses on its potential to produce large supereruptions, the hazards that are much more likely to occur...

New maps of global geological provinces and tectonic plates

New models that show how the continents were assembled are providing fresh insights into the history of the Earth and will help provide a...

Earth’s core: Unexpected flow behavior in liquid metals

Some metals are in liquid form, the prime example being mercury. But there are also enormous quantities of liquid metal in the Earth’s core,...

NOAA shares flashy first imagery from GOES-18 Lightning Mapper

The Geostationary Lightning Mapper (GLM) instrument, onboard NOAA's GOES-18 satellite, is now providing striking lightning observations of the Western Hemisphere. GOES-18 launched on March...

New mapping technology to discover Earth’s resources

For years, scientists have tried to understand the structure of the Earth. One of these scientists is University of Twente geophysicist Dr. Juan Carlos...

The link between temperature, dehydration and tectonic tremors in Alaska

A Kobe University research group has shed light on how low-frequency tectonic tremors occur; these findings will contribute towards better predictions of future megathrust...
