Tanzania’s Ol Doinyo Lengai is the only active volcano known to erupt natrocarbonatite, the coolest lava on Earth: it flows at roughly 500–590°C, against 1,100°C or more for Hawaiian basalt. Fresh flows look black or dark brown in daylight, then react with rain and atmospheric moisture until the mountainside turns chalk-white—as though someone spilled milk over the lava.

Inside T??rkiye???s Tendurek crater, temperatures reach 85 C as volcanic gases rise
2+ day, 21+ hour ago (373+ words) Temperatures reaching 85 degrees Celsius (185 Fahrenheit) have been measured at gas vents inside the crater of Mount Tendurek, one of Türkiye's active volcanic areas, where explorers documented continuing gas, steam and sulfur emissions. Archaeologist, traveler and nature enthusiast Onur Benli and…...
Yellowstone Volcano Observatory monthly update
4+ day, 11+ hour ago (292+ words) RexburgStandardJournal.com The Absaroka volcanoes were active from about 43 to 53 million years ago and probably looked a lot like volcanoes of the Cascade Range look today. Yellowstone Caldera is famous for it's volcanic activity--perhaps even infamous (more than famous!)....
Applied Sciences, Vol. 16, Pages 8893: Scaling of Gas–Melt Decoupling in Silicic Eruptions: Magma Ascent, Connected Permeability, and Atmospheric Confinement
5+ day, 14+ hour ago (461+ words) Gas escape relative to magma ascent is a primary control on degassing, yet its governing parameters are difficult to compare across eruptions and planetary environments. This study develops a reduced-order dimensionless framework for diagnosing local gas–melt separation in connected,…...
New study sheds light on Mercury’s volcanic history
1+ week, 4+ day ago (244+ words) Mercury may have had a much hotter and deeper volcanic history than scientists previously thought, Knowridge reported. Researchers from the Max Planck Institute for Solar System Research and the universities of Münster and Göttingen in Germany have produced the most…...

An Active Volcano May Be Creating a Valuable Metal Deposit Deep Underground
2+ week, 5+ day ago (322+ words) Volcanoes can wreak devastation when they erupt, but they're also a valuable natural resource: the liquids that bubble up from magma are often rich in important metals....
Scientists debunk volcano myths
3+ week, 3+ day ago (572+ words) A volcano does not ‘smoke’, and a magma chamber is not an underground swimming pool “Volcanoes provide spectacular imagery, which makes them a fertile ground for tall tales,” says Poppe. “But simplifications can easily take on a life of their…...
Volcanoes deliver rock older than the continents
3+ week, 5+ day ago (782+ words) No drill has ever reached the mantle, so scientists depend on volcanoes to deliver the samples instead. Lava from Hawaii and Iceland carries helium, ruthenium, and tungsten signatures that point to a source near the boundary with Earth's core, about…...
Three hidden regions may be feeding East Africa’s volcanoes - Dailynewsegypt
3+ week, 5+ day ago (697+ words) From a distance, active and ancient volcanoes in East Africa and across the central Indian Ocean may seem isolated from one another. But they could carry signals from much deeper inside the planet, from regions close to the boundary between…...
