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...

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....

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...

Climate Change Sent Sub-Surface Tremors, Caused Landslide For 9 Days: Study
In September 2023, a 1.2 kilometre-high mountain peak in an East Greenland fjord - a narrow inlet of sea between two steep cliffs - collapsed, causing a tsunami about 200 metres tall.

Mysterious Global Seismic Signal Traced To Greenland Mega-Landslide: Study
A year after a bizarre seismic signal baffled scientists globally, researchers have finally pinpointed its origin. The signal, classified as an "unidentified seismic object", was traced back to a colossal landslide in Greenland's remote Dickson Fjord

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.
