Scientists Discover New Seismic Clue to Predict Mount Etna Eruptions
Scientists studying Mount Etna have found that changes in the “b-value” ratio of earthquakes can signal magma movement before eruptions. Using nearly 20 years of data, this discovery could enhance volcanic early warning systems globally, potentially saving lives in regions near active volcanoes.

Seismic Mystery Solved: NASA’s SWOT Satellite Detects Greenland Mega-Tsunamis
In September 2023, a global seismic mystery puzzled scientists for nine days. New research now confirms it was caused by two mega-tsunamis triggered by landslides in East Greenland. The waves became trapped in a fjord, forming seiches that shook the Earth. Using cutting-edge data from NASA’s SWOT satellite, scientists detected these hidden waves ...

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.

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 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-...

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...

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

Even Google Agrees There’s No Going Back to the Old Office Life
Google, Apple, and almost all other major tech firms are experimenting with the idea of hybrid workplaces as the COVID-19 restrictions forcing its employees to work from home are beginning to ease.

7,800 people affected by quake in China's Xinjiang
A 7.3-magnitude earthquake which struck northwest China's remote and sparsely-populated Xinjiang region yesterday has affected over 7,800 people as seismologists warned that the powerful tremble signals a seismically active period for the Earth.
