Because P waves are the fastest seismic waves, they will usually be the first ones that your seismograph records. The next set of seismic waves on your seismogram will be the S waves. These are ...

In 2021 and 2022, NASA’s InSight lander picked up the tremors coming from the depths of Mars. These Marsquakes were quickly ...

P-waves (P stands for primary ... to the direction in which the wave itself moves. S-waves (S stands for secondary) are shear earthquake waves that pass through the interior of the Earth.

The diagrams show what happens when P waves and S waves pass through the Earth ... It is the slowest of the three types of seismic wave. Surface waves usually have larger amplitude than the ...

Distances from the stations to the earthquake are estimated from the difference between P and S wave arrival times: You have just figured out how far your seismograph is from the epicenter and how ...

When scientists attempt to “see” all the way through the planet, they are generally tracking two types of seismic waves: ...

A recording of an earthquake has recognizable characteristics. Typically, one can recognize the arrival of different wave types. The P waves (the fastest traveling waves), S waves, and Surface waves ...

Key concepts covered include seismic waves, P and S waves, earthquakes, engineering and speed of light. Supports CDE Academic Standards for Earth Science.

Information from three stations can be used in order to locate the epicentre of the earthquake. If we know the time lag between the arrival of P and S waves, we can calculate the distance of the ...
