Mysterious deep-Earth seismic signature explained

New research on oxygen and iron chemistry under the extreme conditions found deep inside the Earth could explain a longstanding seismic mystery called ultralow...

Scientists use seismic waves to measure tornado intensity

Seismic waves generated by tornadoes when they touch down could be used to measure a twister's intensity, according to a new study. The new research...

Drilling into the mysteries of seismic activity

An international expedition aims to better understand seismic activity through samples collected from one of the most geologically active areas in Europe. More than 30...

Database eyes human role in earthquakes

A new database showcasing hundreds of examples of human-triggered earthquakes should shake up policy-makers, regulators and industry executives looking to mitigate these unacceptable hazards...
