Separating mining explosions from earthquakes in South Korea

South Korea is a relatively quiet country, seismically speaking, but a recent study identified more than 182,000 small seismic events—135,000 of which were related to mining explosions, according to a presentation at the ...

Beneath the Earth, ancient ocean floor likely surrounds the core

Through global-scale seismic imaging of Earth's interior, research led by The University of Alabama revealed a layer between the core and the mantle that is likely a dense, yet thin, sunk ocean floor, according to results ...

Seismic imaging provides insight into the Earth's subsurface

The seismic reflection method involves sending acoustic waves thousands of meters under the Earth's surface. The reflected signals provide scientists with information about the characteristics of the subsurface. This is how ...
