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...

Delhi Earthquake: List Of Strongest Earthquakes Tremors In Delhi-NCR
Delhi Earthquake: Delhi is located within Seismic Zone IV, which is considered prone to earthquakes due to its proximity to the Himalayan collision zone.

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...

Gaza Ceasefire Comes Into Force After Delay, Hamas To Release 3 Israeli Hostages Today
After hours of delay, the Gaza ceasefire came into effect on Sunday after Hamas released the names of the first three Israeli hostages to be freed,pausing a 15-month-old war that has brought seismic political change to the Middle East.

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...

Ancient Geological Hotspot Linked to Great Lakes' Depth and Formation
New research reveals an ancient geological hotspot influenced the Great Lakes' formation millions of years ago. As North America drifted over this hotspot, the lithosphere weakened, enabling glacial forces during the Ice Age to carve the deep depressions of these massive lakes. Seismic data supports this theory, showing unusual wave movements benea...

Shenzhou-15 Spacecraft Debris Burns Over Los Angeles During Uncontrolled Reentry
On April 2, 2024, debris from China's Shenzhou-15 spacecraft lit up the Los Angeles sky during an uncontrolled reentry. Scientists employed seismic data to track the sonic booms generated by the debris, analysing its path, speed, and fragmentation. This novel use of seismic tools highlights the risks of increasing space debris and the potential to ...
