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.
Dust May Have Controlled Ancient Human Civilization
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.
Rebirth of a Volcano
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.
The Age of the Earth’s Inner Core Revised
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.
Study Rewrites the Recent History of Productive Cascade Arc Volcanoes
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.
Rare ‘Boomerang’ Earthquake Observed Along Atlantic Ocean Fault Line
Scientists have tracked a 'boomerang' earthquake in the ocean for the first time, providing clues about how they could cause devastation on land.
Plate Tectonics Goes Global
Today, the entire globe is broken up into tectonic plates that are shifting past each other, causing the continents to drift slowly but steadily. But this has not always been the case.
Optical Seismometer Survives “Hellish” Summit of Caribbean Volcano
The heights of La Soufrière de Guadeloupe volcano can be hellish, sweltering at more than 48 degrees Celsius (120 degrees Fahrenheit) and swathed in billows of acidic gas.
Geologists Publish New Findings on Carbonate Melts in Earth’s Mantle
Geologists from Florida State University's Department of Earth, Ocean and Atmospheric Science have discovered how carbon-rich molten rock in the Earth's upper mantle might affect the movement of seismic waves.
