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 ...

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...

Earth’s Inner Core Might Be Slowing Down and Changing Shape, New Study Reveals
Research suggests Earth’s inner core, a metal sphere within the molten outer core, is slowing its spin and reshaping. Seismic wave analyses from earthquakes reveal discrepancies indicating deformation on the core’s surface or changes in rotation. John Vidale, a geophysicist from the University of Southern California, presented these findings, s...

Explained: Fall Of Syria And Its Impact On Power Balance In The Middle East
In a seismic moment for the Middle East, Islamist rebels in Syria announced President Bashar al-Assad's ouster on Sunday after seizing control of Damascus, forcing him to flee and ending his family's decades of rule.

Apophis Asteroid Flyby in 2029: Earth's Gravitational May Impact Asteroid's Surface
Asteroid 99942 Apophis, named after the ancient Egyptian god of darkness, is set to pass incredibly close to Earth in 2029, at just 32,000 km. While there is no risk of a collision, scientists are keen to study the asteroid’s interaction with Earth's gravity. Research led by planetary scientist Ronald Ballouz suggests that this flyby may cause si...

NASA and ISRO Join Forces for NISAR Satellite Launch in 2025 to Track Earth’s Changing Surface
The NISAR satellite, a joint NASA-ISRO Earth observation mission launching in 2025, will provide precise data on shifts in Earth’s surface, focusing on high-risk areas. Using advanced radar technology, the satellite aims to support natural disaster response and infrastructure monitoring by tracking subtle movements in regions prone to earthquakes...

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...

Scientists Identify Seismic Trigger Before 2022 Tonga Eruption; Insight Could Improve Tsunami Warnings
A seismic wave recorded 15 minutes before the massive 2022 Tonga eruption could help scientists improve early-warning systems for remote oceanic volcanoes and mitigate tsunami risks. Researchers found that a rupture beneath the volcano’s caldera allowed seawater to mix with magma, triggering the eruption. This discovery may provide critical lead-...

2022 Tonga Eruption: Public Observations and Scientific Data Illuminate Hunga Volcano's Global Impact
The Hunga volcano eruption near Tonga on January 15, 2022, sent shockwaves and tsunamis across the globe, creating low, booming sounds heard as far away as Alaska. In New Zealand, more than 2,100 public observations of the eruption, from rumbling sounds to animals reacting, helped scientists at GNS Science cross-verify seismic and atmospheric data....
