Did you know that sensitive seismic instruments can pick up the ripples of distant earthquakes? Watch it happen in this animation, which shows the waves from the October 9 magnitude 7.7 earthquake in Panama travel across North and South America.
Each dot in this Ground Motion Visualization (GMV) is a seismic station. When the ground moves up the dot turns red, and when the ground moves down the dot turns blue.
When an earthquake happens, Earth rings like a bell — the waves generated by each earthquake travel both around and through the planet. As they travel further from the earthquake location, the waves get smaller. This is called attenuation. Think of this process like dropping a stone into a pond. The waves are larger closer to the location where the stone hits the water, but become weaker as they travel away.
Earthquake waves are no longer felt by people once they are very far away from the epicenter, but seismic instruments can still feel the subtle disturbances caused by them.
