The study of earthquakes called Seismology, relies on the fact that different materials within the Earth react differently to stress. When a fault slips, energy radiates outward from the focus (the ...

Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...

First global map of mantle earthquakes reveals seismic activity far beneath continents, challenging old ideas about Earth’s ...

A new kind of earthquake has been detected in western Canada, one that shakes the ground slower and longer than typical seismic events. These earthquakes, recorded during hydraulic fracturing for oil ...

A new type of seismic threat is gaining attention among geologists—and it could have serious implications for California. Known as “supershear” earthquakes, these rare but devastating quakes travel ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge ...
