Iris: 1 Component Seismogram: Building Responds to P, S, Surface Waves
Seismic waves travel through the earth to a single seismic station. Scale and movement of the seismic station are greatly exaggerated to depict the relative motion recorded by the seismogram as P, S, and surface waves arrive. [0:50]
Khan Academy
Khan Academy: Seismic Waves and How We Know Earth's Structure: Seismic Waves
Video lecture explores S-waves and P-waves. [8:38]
Khan Academy
Khan Academy: Seismic Waves and Earth's Structure: Refraction of Seismic Waves
Explains how any type of wave can be refracted, and how this applies to seismic waves and to our understanding of the Earth's structure. [9:21]

Iris: 4 Station Seismograph Network Records a Single Earthquake
See a cow and a tree in this narrated cartoon for fun and to emphasize that seismic waves traveling away from an earthquake occur everywhere, not just at seismic stations. [1:31]
Incorporated Research Institutions for Seismology
Iris: Seismic Waves: P, S, and Surface
Video lecture on wave motions and speeds of three fundamental kinds of seismic waves: Primary (P = pressure) waves; Secondary (S = shear); and Surface waves. [3:10]

Iris: Travel Time Curves: How They Are Created
See how travel-time curves are created. [2:52]
Incorporated Research Institutions for Seismology
Iris: Building Resonance: Boss Model Construction & Use
See how a building responds to seismic waves. [2:37]
Incorporated Research Institutions for Seismology
Iris: Fault: Normal Basin & Range With Seismic Stations
A cross section of the shallow crust in the Basin & Range. The earthquake produces seismic waves that bump an array of seismic stations. [0:30]

Joides Resolution: P Wave Velocity
How fast does sound travel through the rocks? And how does seismic velocity vary through different depths? See how scientists measure individual pieces of seafloor samples to get a better understanding of how the cores are related to...
