How can the distance to the epicenter of an earthquake be determined from a seismogram?

Back

By calculating the difference in the arrival time of the P-wave and S-wave.

What are P-waves?

Back

P-waves, or compressional waves, are seismic waves that travel faster than S-waves and compress and expand the material they move through.

What are S-waves?

Back

S-waves, or shear waves, are seismic waves that travel slower than P-waves and move material perpendicular to the direction of wave travel.

What is a seismogram?

Back

A seismogram is a record produced by a seismograph that shows the arrival times of seismic waves from an earthquake.

What is the difference between the epicenter and the focus of an earthquake?

Back

The focus is the point inside the Earth where the earthquake originates, while the epicenter is the point directly above it on the Earth's surface.
