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.
Rising waters: Paris, January 29, 2018.
It was the Seine’s rise and fall, in response to heavy rain, that inspired our current understanding of river systems.
A drying climate caused a mass extinction among plants, but paved the way for the ancestors of modern reptiles, mammals, and birds.
The extinction of dinosaurs is one of the many periods of mass extinctions on earth.
Scientists believe since 2010 we have entered the sixth period of mass extinction. CO2 emissions will change the lives of plants and animals in the next three to four decades.
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.
It turns out that the world is about 4,600,000,000 years old. That’s 4.6 billion years. That’s pretty old!

The world is made of tiny building blocks called 'elements'. Scientists have worked out how fast some elements change into other elements. That gives us a very big clue about how old the Earth is.
As many as 20 people are dead and dozens missing following the Southern California mudslides.

In response to mudslides that have killed at least 20 people in Southern California, a geologist calls for more resources to study and map landslide hazards so residents can understand the risks.
Children observe the eruption of Mount Agung on Bali, November 29, 2017.

'Volcano forensics' involves a mixture of modern day monitoring and analysis of past eruptions. Geologists use volcanic rocks as a kind of time capsule to assess what happened previously.
Just a burp, or indication of coming disaster?

How do scientists predict volcanic eruptions? To do so with accuracy, they need to know the individual volcano and its history very well.
The legacy of the dirtiest of fuels – coal – has the potential to deliver a low carbon energy future.
Lynn Margulis receiving the National Science Award from U.S. President Bill Clinton in 1999.
Lynn Margulis (1938-2011) was a courageous scholar whose remarkable work on the role of symbiosis in evolution stands as a magisterial contribution of science.
The continent of Australia is a mixture of land masses of differing ages.
The world's oldest known material is from Western Australia. But for much of Australia's geological past, the eastern states simply didn't exist. They're relative newcomers to our ancient continent.
Volcanologists often visit active volcanoes in order to observe eruptions and collect samples of lava and ash.
Volcanologists study the formation and eruptions of volcanoes - surely one of the most interesting jobs around. However, it can also be very dangerous.
Barkly Pass, the stratotype for the Elliot Formation. These beautiful rocks hold ancient secrets.
The earth's own magnetic field offers a useful way to measure the age of rocks - information that can help unpack ancient events and aid our understanding of the present.
Vandalised site, showing fresh sand along the edges of the slab where it has been lifted and the holes left by the removal of two blocks in the centre.
Latest development in 'Crete feet' find serves as a reminder of the challenges facing dig sites.
“Snowball Earth” happened around 700 million years ago.
Earth's thermostat can fail spectacularly at times. Around 700 million years ago, huge volcanic eruptions triggered "Snowball Earth".
Salt flows down rivers to the ocean.
A special combination of rain, rocks and subsea volcanoes makes the sea salty.
Foot for thought.
A new study can't rule out the possibility that human ancestors lived on Crete at the same time as they evolved in Africa.
