IRIS: EFFECT OF SEISMIC WAVES ON BUILDINGS

1-Component Seismogram: Building responds to P, S, surface waves

How many different ways can an earthquake shake us?

An earthquake generates seismic waves that (1) penetrate the Earth as body waves (P & S) or (2) travel as surface waves (Love and Rayleigh). Each wave has a characteristic speed and style of motion. Here we exaggerate the motion by bouncing a building to show what sensitive instruments record as seismic waves arrive at the station. Animation to characterize behavior of three seismic waves. The seismogram shows the arrival times of the three generalized waves. This image just shows a single body-wave path through the Earth to avoid cluttering the image. Waves travel in all directions from an earthquake.
