While earthquake locations are normally done with a computer that can quickly determine the paths of seismic waves through the Earth to many seismic stations, you can get a good estimate of an ...

there is a sudden change in direction due to refraction. A surface wave travels along the surface of the Earth. It is the slowest of the three types of seismic wave. Surface waves usually have ...

Most studies of the seismic waves created by earthquakes look at ... itself in long vertical vortices running in a north–south direction, like giant waterspouts. The turbulent movement of ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history.
