An earthquake is felt in several locations in South America.

Remember that there are 2 types of waves that travel through the Earth: P (primary) waves and S (secondary) waves.

The time between the arrival of P and S waves at a seismograph station helps us determine how far away the station is from the earthquake's epicenter.

The arrival of the P and S waves are marked on the following seismographs.

Circles were drawn using the epicenter distances for each location.

The epicenter is located at the intersection of the three circles.

Using the drawing tools to mark the location of the earthquake.

Using the drawing tools to mark the location of the earthquake.

Compare these 2 images. Where are earthquakes and volcanoes most likely to be found?

Convection cells are the driving force behind plate tectonics. Where do they occur?

What is subduction?

Which feature would you expect to find at a convergent subduction boundary?

Which feature would you expect to find at a convergent collision boundary?

What occurs when the energy is released at a transform boundary?

What is the S-P interval time for Talca?

What is the S-P interval time for Santiago?

What is the S-P interval time for Orsorno?

The dark diagonal line on the graph represents the relationship between the S-P time interval and the distance the waves have traveled.

Each city is marked on the graph.

What is the distance from the Talca station (red) to the epicenter?

What is the distance from the Santiago station (green) to the epicenter?

What is the distance from the Orsorno station (purple) to the epicenter?
