Venus’ Ancient Layered, Folded Terrain Points to Volcanic Origin
An international team of researchers has found that some of the oldest terrain on Venus, known as tesserae, have layering that seems consistent with volcanic…
Massive Volcanism Sent Great Waves of Carbon Into the Oceans Over Thousands of Years – Far Outpaced by Humans Now
The closest analog to modern times is no longer very close, study finds. A new study of an ancient period that is considered the closest…
Rebirth of a Volcano: Photogrammetric Data Shows Volcanoes Have “Memory”
For the first time, long-term photogrammetic series document the “life cycle” of a volcano. The analyses shows that volcanoes have a kind of memory. Volcanoes…
Volcanism Under the Heart of Northern Europe: New Evidence From Thousands of GPS Antennas
Scientists have discovered new evidence for active volcanism next door to some of the most densely populated areas of Europe. The study ‘crowd-sourced’ GPS monitoring…
Lava Tubes on Mars and the Moon May Be Suitable for Planetary Bases – Up to 1,000 Times Wider Than Those on Earth
The international journal Earth-Science Reviews published a paper offering an overview of the lava tubes (pyroducts) on Earth, eventually providing an estimate of the (greater)…
Global Cooling 13,000 Years Ago Was Caused by Volcanic Eruptions, Not Meteors
Analysis of sediment found in Hall’s Cave shows volcanic eruptions responsible for cooling of Earth around 13,000 years ago. Ancient sediment found in a central…
Explosive Secret Discovered Hidden Beneath Seemingly Trustworthy Volcanoes
An international team of volcanologists working on remote islands in the Galápagos Archipelago has found that volcanoes that reliably produce small basaltic lava eruptions hide…
Planetary Researchers Surprised to Find a “Ring of Fire” on Venus
ETH researchers used computer simulations to classify the current activity of corona structures on the surface of Venus. To their surprise, they found a previously…
Scientists Identify 37 Active Volcanoes on Venus – “Planet’s Interior Is Still Churning”
