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...

Romania’s ‘Living’ Rocks Expand and Multiply in a Strange Natural Process
Trovants, mysterious geological formations found in Romania’s Costești region, are known for their unique ability to grow and multiply. These rocks, formed millions of years ago due to seismic activity, consist of a hard stone core surrounded by a porous sandstone shell. When rainwater rich in minerals like calcium carbonate seeps into the rock,...

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...

New Algorithm Uses Fiber Optic Cables to Improve Earthquake Detection Globally
Researchers have developed an algorithm that converts fiber optic cables into seismic sensors, improving earthquake detection and early warning systems. The method integrates fiber optic and traditional seismometer data, overcoming challenges in earthquake monitoring. The technology could also help detect seismic activity in volcanoes and glaciers....

Greece Issues Increased Seismic Activity Warning In Santorini
Greek authorities have advised people on the Aegean island of Santorini to shut schools on Monday, avoid two small ports and refrain from gathering in indoor spaces after increased seismic activity in the area over recent days.

Seismic Data from NASA’s InSight Might Solve the Mystery of Mars’ Dichotomy
NASA’s InSight mission has provided seismic data shedding light on the Martian dichotomy, the split between Mars’ northern lowlands and southern highlands. Findings from the mantle’s seismic wave analysis suggest the split stems from ancient tectonic activity and magma dynamics, rather than asteroid impacts. Variations in crust thickness and ...

Scientists Uncover New Hidden Process That May Explain Earthquake Triggers
A new study has revealed a hidden mechanism that could explain how creeping stress along tectonic plates can lead to catastrophic earthquakes. The research, involving laboratory experiments with plexiglass, found that slow, aseismic movements at fault lines can build up energy. Once a critical point is reached, the energy is released suddenly, trig...

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...

Scientists Predict Under Sea Volcano Eruption Near Oregon Coast in 2025
Axial Seamount, an undersea volcano located off the coast of Oregon, is showing signs of an impending eruption, with scientists predicting it could occur as early as 2025. The volcano’s surface has been swelling, and seismic activity is increasing, both of which mirror patterns seen before previous eruptions. Researchers have been closely monitor...

Asteroid Apophis Could Experience Surface Changes Due to Earth’s Gravity During 2029 Flyby
The asteroid Apophis, named after the ancient Egyptian god of chaos, is set to pass extremely close to Earth in 2029, potentially causing seismic activity and landslides on its surface due to Earth's gravity. These changes could alter Apophis’ surface, providing a rare opportunity to observe asteroid dynamics in real-time. A team from Johns Hopki...

SWOT Satellite Observes Seismic Tsunami Event in Greenland’s Dickson Fjord
The Surface Water and Ocean Topography (SWOT) satellite, a joint mission by NASA and France’s CNES, has observed a significant tsunami event in Greenland’s Dickson Fjord. Triggered by a massive rockslide in September 2023, the tsunami lasted for nine days and generated seismic signals recorded globally. The satellite's advanced radar technology...

Moon's Seismic Activity Likely Linked To Past Meteorite Impacts, Says ISRO
Seismic activity in the Moon's soil could be due to impact from meteorites in the past or local heat-related effects, according to ISRO's preliminary analysis of data received from Chandrayaan-3's quake-detecting instrument.
