3 cards from this section. Quick, good the night before a test.
What does the Body Wave Magnitude (Mb) scale measure?
Think about which waves are the fastest.
Which type of magnitude scale focuses on surface waves?
Consider which waves travel along the surface.
What does the Body Wave Magnitude scale primarily measure?
Focus on which type of wave is involved.
True or False: Surface Wave Magnitude is used primarily for small earthquakes.
Consider the type of damage caused by larger earthquakes.
If an earthquake has a Body Wave Magnitude of 6.0 measured far from the source, but close stations report Surface Wave Magnitude of 7.0. Discuss how the different scales help in understanding the event.
Think about the range and applications of each scale.
Design a theoretical scenario where an earthquake measures differently across various magnitude scales. What implications would this have for emergency plans?
Focus on planning for the most damaging effects.
