Mount Lassen awoke in a brief series of eruptions between 1914 and 1917. This week marks the centennial of Lassen's sensational eruption in a mushrooming column of ash seen as far away as Eureka and Sacramento.
Intensive research has laid bare the workings of gigantic "internal waves" that roil the deep seas. The results will advance climate models and make a wide range of marine activities more reliable.
Maybe that old song ought to say that April flowers bring May showers. A new study shows that pollen grains break up into huge numbers of tiny pieces that are active in triggering cloud formation.
Squid and octopuses are famous for their "live fast, die young" strategy, but scientists have just discovered a striking exception: the bizarre species known as vampire squid.
A young paleontologist has figured out how to tell male and female stegosaurs apart from the rows of plates upon their backs.
A new study of fossils on an island in the Arctic Ocean show a major episode of extinction that qualifies as a new "great dying."
Tambora brought the world a taste of apocalypse 200 years ago. Today we have better tools to monitor volcanoes like it, but the next eruption of its size will still challenge civilization.
Tsunamis are a worldwide menace with specific local threats. It pays to learn your local situation and keep the knowledge fresh in your community.
Large earthquakes are in our future. When one strikes, there are ways you can help scientists study the event using your phone.
New data from the ancient ice of a tropical glacier shows that lead in gasoline tainted the Earth with the toxic metal far more than any other source, past or present, human or natural.
Geologists are familiar with something most of us have never seen—spherules, or microscopic balls of natural glass that hide in sediments all over the world. A new study reports a previously unknown kind of spherule that’s forged during volcanic eruptions as lightning lashes roiling clouds of hot ash.
A long record of atmospheric observations has put an "official" stamp on the foundation of climate-change science: the greenhouse effect really works the way we've always said it does.
Scientists must play catch-up to industry as we figure out ways to use the deep underground without triggering earthquakes.
Our best climate models, combined with our best climate records, foresee at least a century of profound drought in the Midwest and Southwest.
In the Internet age, many scientists are questioning the traditional publishing model. As we flounder through the digital revolution, it's intriguing to look back at the print revolution of the early Renaissance, which created comparable social and scientific upheaval.
The large asteroid Vesta has added flows of material rich in water to its bag of tricks. It's just one more way this small world acts like a proper planet.
