PROBLEM: How can a seismogram tell you the intensity of an earthquake?

PREDICTION:

EXERCISE I. Examine the seismograms on the next pages. Label them with a "P" and an "S" where you think the first P (primary wave) and S (secondary wave) waves occur. 

EXERCISE II. Each seismogram records a different earthquake. Using a U.S. placemat find find the appropriate areas of each earthquake. Examine where each seismogram was recorded. Assuming that this was near the epicenter of the earthquake, describe the seismogram: does it record a small, moderate, or large earthquake? Does the shaking happen all at once, or is it spread out? In addition, describe the kinds of damage that may have happened at the epicenter.

	DESCRIPTION OF DAMAGE
seismogram 1. location: intensity:
seismogram 2.    location: intensity:
seismogram 3.    location: intensity:
seismogram 4.    location: intensity:

CONCLUSION: Can scientists predict the types of damage that may happen during an earthquake? How?
