Iceland's Reykjanes Peninsula Volcano Erupts For 9th Time Since 2023
A volcano erupted on Wednesday in Iceland's Reykjanes peninsula in the southwest, weather authorities said, the ninth eruption to hit the region since the end of 2023.

Massive Continent-Sized Blobs Deep in Earth’s Mantle May Be Over a Billion Years Old
Massive mantle formations, called LLSVPs, have been found to be over a billion years old. These structures, sitting 3,000 km beneath the surface, slow seismic waves, indicating unique physical and compositional properties. Their stability suggests they influence Earth's geological processes, including volcanic activity and tectonic movements. Scien...

Increased Seismic Activity at Mount Spurr Raises Eruption Concerns
Seismic activity at Mount Spurr, Alaska, has intensified over the past ten months, with recent earthquakes shifting towards Crater Peak, a vent that erupted in 1992 and 1953. Scientists estimate a 50 percent chance of an eruption at Crater Peak, though the main crater remains stable. If an eruption occurs, ashfall and air travel disruptions could b...

Earthquake Swarm Near Santorini Triggers Emergency Response from Greek Authorities
Greek authorities have closed schools and deployed emergency teams in response to an increasing earthquake swarm near Santorini. The tremors, which began last week, have been intensifying in frequency and magnitude, with the strongest recorded at magnitude 5. Experts have determined that the seismic activity is caused by fault movement, rather than...

Swarm of 130 Earthquakes Rattles One of Iceland's Largest Volcanoes, Signal Possible Eruption Risk
Over 130 earthquakes struck Iceland’s Bárðarbunga volcano within hours on January 14, including a significant 5.1 magnitude quake. The Bárðarbunga system, Iceland's largest volcanic zone, has a history of major eruptions, with the 2014–2015 event producing a lava field larger than Manhattan. Experts at the Icelandic Meteorological Office ar...

Gold-Sulfur Complex Found to Play Crucial Role in Gold Deposit Formation
An international team of scientists, led by Adam Simon, has uncovered the role of a gold-trisulfur complex in gold deposit formation. The research, published in the Proceedings of the National Academy of Sciences, reveals how this complex forms in the Earth's mantle under specific pressure and temperature conditions, especially in subduction zones ...

TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals
A new study published in Nature Astronomy proposes that TRAPPIST-1b, the innermost planet in the TRAPPIST-1 system, might have a carbon dioxide-rich atmosphere. This discovery comes from new data showing a reflective haze in the planet's upper atmosphere. Scientists are also investigating the possibility of volcanic activity based on the planet’s...

Chang’e 5 Probe Reveals Volcanic Activity on the Moon Occurred Much Earlier Than Previously Believed
China's Chang'e 5 mission has brought new insight into the Moon's volcanic history, suggesting that the volcanic activity might have taken place much sooner than previously believed. Samples of lunar soil, returned to Earth in 2020, contain glass beads formed by volcanic eruptions just 120 million years ago. This is a significant discovery, as it c...

Signs Of Extensive Volcanic Activity Discovered On Mars' Elysium Planitia
The findings have implications for research surrounding whether Mars could have harbored life at some point in its history, according to the authors.

Lunar Rocks From China Mission Show Moon Volcanically Active Recently
The first lunar rocks brought back to Earth in decades show the Moon was volcanically active more recently than previously thought, Chinese scientists said Tuesday.

"Ballistic Blocks" Shoot From Hawaii Volcano, May Mark Start Of Violent Eruptions
"Ballistic blocks" the size of microwave ovens shot from Hawaii's Kilauea volcano on Wednesday in what may be the start of explosive eruptions that could spew huge ash plumes and hurl smaller rocks for miles (km), the US Geological Survey said.

Hundreds Evacuated in El Salvador as Volcanic Activity Picks up
More than 1,000 people in El Salvador were evacuated from the area around the simmering Chaparrastique volcano in the east of the Central American country as a precautionary measure against a possible eruption, the government said on Monday.
