Seismic waves that cause the most damage at Earth's surface.
What are surface waves.
Measures the total energy released by an earthquake.
What is the moment magnitude scale?

What is through triangulation:
1. Measure time from P-waves to S-waves
2. Calculate distance on a speed graph
3. graph 3 points and locate where they all intersect
Seismic waves originate here.
