How scientists pinpoint the exact origin of an earthquake

Determining the Epicenter Distance of an Earthquake · 4:09 · Video: Mike Sammartano · Watch at the source

In short: Locating an earthquake's epicenter requires more than just feeling the ground shake. This video demonstrates the technical process of using seismogram readings and reference tables to calculate precise distances from the source.

The video explores the methodology of earthquake analysis by interpreting seismograms—the visual records of seismic waves. By analyzing these readings, scientists can determine the distance between the epicenter and various recording stations.

A key component of this process involves utilizing Earth Science Reference Tables. The tutorial provides a practical look at how these data sets are applied to transform raw seismic data into geographical coordinates, offering a clear look at the mechanics of geophysics.
