Exploration Questions: Earthquakes

1. After the 2010 earthquake in Port-au-Prince, Haiti, a team of geologists make a detailed soil map of the city. What soil properties were they mapping? Why did they do this? What tools did they use to measure these properties?
2. Why are geologists in the Pacific Northwest studying layers of sediment along the banks of tidal creeks? Why would they be interested in a layer of sand between salt marsh peat and tide flat mud?
3. Explain how each of the following tools or methods helps scientists reconstruct the geologic history of a fault:
• LANDSAT imagery and aerial photography
• Trenching
• Radiocarbon dating
