How hard does an Earthquake shake?
How could we determine how accurate the student demos of shaking were?

What other factor(s) might affect the amount of damage to a house besides the ground acceleration? • Duration of shaking • Frequency of shaking • Physical construction of buildings (shape, natural frequency, mass, quality)
How would you expect shaking to vary in the region around the earthquake? The damage?
