Question 1.
What does Ms stand for and what does it measure?
Show hintHide hint
Think about what types of waves surface waves are.
Question 2.
Name the two types of surface waves associated with Ms.
Show hintHide hint
Recall which waves travel along the Earth's surface.
3Question 3.
What is the primary basis for calculating Surface-Wave Magnitude?
- Body waves
- Surface waves
- P-waves
Show hintHide hint
Recall the main waves that travel along the Earth's surface.
4Question 4.
True or False: Surface-Wave Magnitude is calculated over a period of approximately 20 minutes.
- True
- False
Show hintHide hint
Think about the correct time interval for such calculations.
Question 5.
A seismic event generates surface waves with a recorded amplitude of 1 meter. If another event records 0.5 meters, what can you infer about the potential damage each event could cause?
Show hintHide hint
Think about the relationship between wave amplitude and damage potential.
Question 6.
An earthquake's Surface-Wave Magnitude is recorded as Ms 6.5. How might engineers respond to this magnitude in terms of building designs?
Show hintHide hint
Consider building materials and design strategies that mitigate earthquake impacts.
