InSight Mission Uncovers Chaotic Structure Locked Inside Mars’ Interior
NASA’s InSight mission uncovered Mars’ mantle as chaotic and fractured, resembling a Rocky Road brownie rather than a layered planet. Seismic data revealed ancient fragments, some over 4 km wide, preserved by a rigid crust for more than four billion years. The findings offer fresh insights into Mars’ explosive past and the evolution of rocky ...

Scientists Discover Hidden Mantle Layer Beneath the Himalayas Challenging Century-Old Theory
For decades, geologists believed the Himalayas were built on a double layer of continental crust. New research overturns that view, revealing that a dense slab of mantle rock actually wedges between India’s and Asia’s crusts beneath the range. This “mantle sandwich” better explains seismic data and how the mountains remain so stable while r...

Mars' Interior Holds Evidence Of Violent Early History, NASA Scientists Confirm
NASA scientists have discovered massive fragments of ancient planetary collisions buried deep in Mars' mantle, using seismic data from the InSight lander.

Explained: Ring Of Fire, Where The Strongest Earthquakes Occur
The Ring of Fire is a 40,000-km horseshoe-shaped belt around the edges of the Pacific Ocean, known for its intense seismic and volcanic activity.

Meteor Strike May Have Triggered Massive Grand Canyon Landslide 56,000 Years Ago
A meteorite strike in northern Arizona may have triggered a massive Grand Canyon landslide 56,000 years ago. Researchers found ancient driftwood and lake sediments indicating a paleolake formed after the Colorado River was dammed. The study suggests seismic waves from the Meteor Crater impact caused the landslide. Findings were published in the jou...

Why Alaska's Latest 7.3 Magnitude Earthquake Has Got Scientists' Attention
Wednesday's magnitude 7.3 earthquake off Alaska's Aleutian Islands chain struck in a region that has experienced a handful of powerful quakes within the last five years - including one that shook communities almost exactly two years earlier.

Japan Urges Small Island Residents To Evacuate As 1,000 Quakes Hit Area
Japanese authorities urged the 89 residents of a small southern island to evacuate after a strong earthquake on Thursday, the latest of more than 1,000 recent jolts to hit the area.

Study Explains How Climate Change May Be Causing Minor Tremors In Alps
A new study links climate change-induced glacier melt in the Alps to a surge in minor earthquakes, warning that seismic risk may rise globally as glaciers continue to shrink.

NASA Satellite Captures Alaska's Iliamna Volcano From Space Amid Seismic Spike
The volcano is currently considered dormant as the most recent reported eruption occurred in 1876.

‘Ghost’ Plume Found Beneath Oman May Explain India’s Ancient Tectonic Shift
A buried magma plume beneath Oman’s Salma Plateau may have nudged India’s tectonic path during its collision with Eurasia, scientists report. Named “Dani,” the amagmatic plume caused no eruptions but likely altered continental motion 40 million years ago. This discovery redefines how silent, deep mantle forces can reshape continents without...

Earthquake Of Magnitude 5.1 Hits Iran, Sparks Theories Of Nuclear Testing
The earthquake has now triggered a wave of speculations about whether Tehran has tested a nuclear weapon. It has also sparked concern because it struck near a city with a space and missile complex.

Seismic Mystery Solved: NASA’s SWOT Satellite Detects Greenland Mega-Tsunamis
In September 2023, a global seismic mystery puzzled scientists for nine days. New research now confirms it was caused by two mega-tsunamis triggered by landslides in East Greenland. The waves became trapped in a fjord, forming seiches that shook the Earth. Using cutting-edge data from NASA’s SWOT satellite, scientists detected these hidden waves ...
