How do seismologists locate an earthquake’s epicenter?
Quick Answer
They compare the arrival times of P waves and S waves at several stations to triangulate the source.
The Full Story
When an earthquake occurs, P waves arrive before S waves because they travel faster through Earth. By measuring the time gap between those arrivals at a seismograph station, scientists can estimate how far away the epicenter is. Using data from at least three stations, they triangulate the location. This method is a core tool in earthquake monitoring and helps map active fault systems around the world.
Key Facts
1.P waves arrive before S waves
2.At least 3 stations are needed to triangulate an epicenter
3.The method uses wave arrival times
