Anatomy of a Tsunami What causes a tsunami? How are tsunami related to earthquakes?
Click on Launch Interactive on this web page featuring the devastating tsunami of December 26, 2004. Excellent simulation of the cause and effect of "seismic sea waves".
Waves on a String Simulation Change some of the variables with this simulation. Try oscillation and pulsing. What happens to amplitude and frequency?
Pacific Northwest:Tsunamis and Earthquakes Learn more about the causes and history of large earthquakes and tsunamis in Washington State, Sumatra, and huge quake and tsunami in Japan in 2011. Also linked is some video footage of the Sumatra and Japan tsunamis.
P-Waves and S-Waves animation Try this visualization to see how particles within the Earth respond to each of these types of seismic waves.
P-Waves, S-Waves, and Surface Waves Animation This animation shows both the movement of the three basic waves (P, S, and surface) and the effect of the waves on a building. The three seismograms produced by a modern seismograph station show that the P wave is more visible on the vertical component and the S wave amplitude is larger on the horizontal components.
