Mars Crater Offers Window on Temperatures 3.5 Billion Years Ago

Once upon a time, seasons in Gale Crater probably felt something like those in Iceland. But nobody was there to bundle up more than 3 billion years ago.

Understanding Origins of Arizona’s Sunset Crater Eruption 1,000 Years Ago

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.

Volcanic Eruptions Directly Triggered Ocean Acidification During Early Cretaceous

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

Crystals May Help Reveal Hidden Kilauea Volcano Behaviour

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.

Cluster of Alaskan Islands Could be a Super Volcano

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

Geoscientists Use Zircon to Trace Origin of Earth’s Continents

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.

Archipelago in Ancient Doggerland Survived Storegga Tsunami 8,000-Years-Ago

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

Geoscientists Discover Ancestral Puebloans Survived From Ice Melt in New Mexico Lava Tubes

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.

Lost and Found: UH Geologists ‘Resurrect’ Missing Tectonic Plate

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

Study Into Earth’s Crust Finds Heat Source That May Stabilise Continents

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.

Disproportionate Extinction of South American Mammals When Americas Collided

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.

Geoscientists Discovers Causes of Sudden Volcanic Eruptions

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