Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Scientists have known that seismic waves slow down when passing through ultra-low velocity zones, or ULVZs, but only knew they existed around hotspots that create volcanic island chains. Now, a new ...

Researchers have mathematically elucidated how the presence of crystals and gas bubbles in magma affects the propagation of seismic P-waves. A novel equation was derived to describe the travel of ...

Earth's core might be layered like an onion, according to a new study that looked at the anomalous nature of waved in the ...

Geophysicists find link between seismic waves called PKP precursors and anomalies in Earth's mantle that are associated with hotspots associated with volcanism on the surface. For the decades since ...

BUTTE, Mont. — Envision this scenario: You are going about your day. All is calm and quiet until suddenly, the ground beneath your feet begins to shake, and items within your home or workspace begin ...

Earthquakes, volcanic eruptions, shifting tectonic plates - these are all signs that our planet is alive. But what is revealed deep inside the earth surprises laymen and scientists alike: Almost 3000 ...

Japan's Chubu Electric Power said on Monday it might have used a different method than explained to regulators to select representative seismic waves during the review of two reactors at its Hamaoka ...

Chubu Electric Power shares tumbled by the most in more than 13 years on Tuesday after the Japanese utility disclosed ...
