Geology

Around AD 1085 AD, along the southern rim of Northern Arizona's elevated Colorado Plateau a volcano erupted, forever changing ancient Puebloan fortunes and all nearby life.

Around 120 million years ago, the earth experienced an extreme environmental disruption that choked oxygen from its oceans.

Scientists striving to understand how and when volcanoes might erupt face a challenge: many of the processes take place deep underground in lava tubes churning with dangerous molten Earth. Upon eruption, any subterranean markers that could have offered clues leading up to a blast are often destroyed.

Scientists suggest that a small group of volcanic islands in Alaska's Aleutian chain might be part of a single, undiscovered giant volcano.

Geoscientists have long known that some parts of the continents formed in the Earth's deep past, but the speed in which land rose above global seas -- and the exact shapes that land masses formed -- have so far eluded experts.

Doggerland, dubbed “Britain’s Atlantis” is a submerged landmass beneath what is now the North Sea, that once connected Britain to continental Europe.

For more than 10,000 years, the people who lived on the arid landscape of modern-day western New Mexico were renowned for their complex societies, unique architecture and early economic and political systems.

The existence of a tectonic plate called Resurrection has long been a topic of debate among geologists, with some arguing it was never real.

Rocks from the Rio Grande continental rift have provided a rare snapshot of active geology deep inside Earth's crust, revealing new evidence for how continents remain stable over billions of years, according to a team of scientists.

When the Isthmus of Panama rose from the sea to connect North and South America millions of years ago, mammals could cross the bridge in both directions.

Tiny crystals, ten thousand times thinner than a human hair, can cause explosive volcanic eruptions.

When early humans began to travel out of Africa and spread into Eurasia over a hundred thousand years ago, a fertile region around the eastern Mediterranean Sea called the Levant served as a critical gateway between northern Africa and Eurasia.

Volcanoes are born and die - and then grow again on their own remains. The decay of a volcano in particular is often accompanied by catastrophic consequences, as was the most recent case for Anak Krakatau in 2018.

By creating conditions akin to the center of the Earth inside a laboratory chamber, researchers have improved the estimate of the age of our planet's solid inner core, putting it at 1 billion to 1.3 billion years old.

Volcanic eruptions in the Cascade Range of the Pacific Northwest over the last 2.6 million years are more numerous and closely connected to subsurface signatures of currently active magma than commonly thought, according to newly published research.
