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.

‘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...

Greenland's 650-Foot Mega-Tsunami Shook Earth For 9 Days, Satellite Data Confirms
A massive landslide in Greenland's Dickson Fjord in 2023 triggered a 200-metre-high tsunami, causing global seismic vibrations for nine days.

Are Earthquakes Hiding Secret Nuclear Tests? New Study Raises Concerns
A new study suggests that earthquakes could potentially hide secret nuclear tests by masking seismic signals, making detection difficult.

Farallon Slab Beneath Midwest Pulls Crust Downward, Causing Widespread Thinning
A tectonic slab buried 660km beneath the central US is pulling surface materials downward, causing the Earth's crust to thin across a wide region. The slab, a remnant of the Farallon plate, has been identified through seismic imaging and simulations as the cause of this geological activity. Researchers say this underground movement extends beyond t...

Myanmar Earthquake: Magnitude 7.7 Hits Mandalay, Devastates Region
On March 28, 2025, a magnitude 7.7 earthquake struck Myanmar, resulting in at least 144 deaths and hundreds injured. The tremor, centered in Mandalay, also affected neighboring countries such as Thailand and China. The earthquake, which occurred along the Sagaing Fault, is part of ongoing tectonic activity in the region, where the Indian Plate is s...

Mount Spurr Volcano in Alaska Shows Signs of Possible Eruption
Mount Spurr, a stratovolcano west of Anchorage, has shown rising seismic activity, gas emissions, and melting snow, suggesting magma movement beneath the surface. Scientists at the Alaska Volcano Observatory believe an eruption is becoming more likely, with historical eruptions in 1953 and 1992 at Crater Peak having sent ash plumes over Anchorage. ...

New Seismic Data Challenges Earth's Inner Core Structure, Reveals Surprising Findings
Recent seismic data from 121 earthquakes recorded over three decades challenges previous beliefs about Earth's inner core. Researchers from the University of Southern California discovered structural changes in the core, suggesting it may not be as solid as once thought. These anomalies, observed while studying the core's slowing rotation, could of...

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...
