Research into volcanic activity in the waters off Indonesia shows how active this region is and how destructive landslide-caused tsunamis can be.
It’s core to life on Earth.
The Earth's core is cooling down, and one day it will be completely solid – when that happens, Earth might look a lot like Mars.
The scientific drilling ship JOIDES Resolution arrives in Honolulu after successful sea trials and testing of scientific and drilling equipment.
The ocean floor holds unique information about Earth's history. Scientific ocean drilling, which started 50 years ago, has yielded insights into climate change, geohazards and the key conditions for life.
Cumberland Island National Seashore off the coast of Georgia.
How do the narrow ribbons of sand that line the Atlantic and Gulf coasts withstand the force of hurricanes? The answer lies in their shape-shifting abilities.
What’s going on 150 kilometers below the Earth’s surface?

A new array of seismometers provides a glimpse of what's happening deep beneath this geologic fault. New data help explain why the north and south of the region are more seismically active than the middle.
Long’s Peak framed by rock outcrop, Rocky Mountain National Park, Colorado.
Scientists have long thought most nitrogen in Earth's ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
Seismic shockwaves after a meteorite’s collision could affect systems all over the planet.
Research suggests a new threat to life on Earth from the meteorite's crash: Via seismic waves, the impact triggered massive undersea eruptions, as big as any ever seen in our planet's history.
Fires break out across San Francisco after the April 18, 1906 earthquake.
According to current forecasts, California has a 93 percent chance of an earthquake with magnitude 7 or greater occurring by 2045. Early warning systems, now in development, could limit casualties and damage.
A new study has found a way to predict eruptions at Mount Etna within two weeks.

While the Montecito, California mudslides took 20 lives, landslides kill far more people in developing countries. Tighter construction standards and early warning systems could help reduce their toll.
Where there’s smoke, there will be lava?

How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.

Why use satellites to study Earth's climate? Researchers leading a new mission explain how images from space will help them analyze which parts of the Americas soak up the most carbon.

President Trump's 2018 budget request cuts funding for NASA Earth observation research and cancels four missions. Weather forecasters, businesses, scientists and the armed forces rely on this data.
You can only truly understand the weather by flying above the clouds.
Far from being "politicised science", as a Trump advisor has claimed, NASA's satellite monitoring has been a crucial help in understanding the planet we live on.
New research suggests how asteroids may have helped create conditions for life on Earth. But we shouldn't get too carried away with the idea – yet.
Amatrice’s clock tower has survived quakes across the centuries.
Amatrice's still-standing ancient clocktower has become an iconic image from last week's deadly earthquake. But it is not the only unusual survivor.
Hot spot for much-needed research.
The House proposes slashing funding for earth science from NASA's budget, yet this science is critical to understanding – and coping with – the dramatic effects of a warming Arctic around the world.
What can what’s on the moon tell us about our home planet?
The moon might harbor bits of the Earth that blasted off our planet billions of years ago. These lunar time capsules could hold secrets about conditions here at home back when life was first emerging.
One of the stalagmites used in this study. The blue-green fluorescence is due to the light from the camera flash.
Stalagmites in Scottish preserve 3,000 years of climate history, suggesting human migration is linked to wet and dry periods.
