A travel time curve is a graph of the time that it takes for seismic waves to travel from the hypocenter of an earthquake to seismograph stations at varying distances away. P and S waves travel at different speeds, and the difference in their arrival times can be used to determine how far away an earthquake is. https://loom.ly/sfJPMYw | EarthScope Consortium
