Scientists developed an early warning system to determine when an earthquake is going to take place by analyzing the behavior of two types of waves: P waves and S waves. P waves are the ones that travel faster and are produced first, they travel in an exact opposite direct of where the earthquake is produced. On the other hand, s waves or secondary waves are slower and travel in a perpendicular way. Scientist detect when these waves are generated in specialized centers.
