This animation shows the waves from the August 10 magnitude 7.4 earthquake in Colombia ripple across North and South America.
Waves generated by an earthquake travel around and through the Earth, but they get smaller, or attenuate, as they move away from the earthquake location, just like ripples in a pond. Once the earthquake waves are far enough away from the epicenter, they can no longer be felt by people, but they can still be detected by sensitive seismic instruments.
