Earthquakes in New York State – Report Sheet



Earthquakes in New York State – Report Sheet

Analysis Questions: All of the following questions must be answered in the form of a complete and grammatically correct sentence.

1. According to Figure 1, what is the seismic risk in the Hinsdale area?

2. Use the New York State map in our Earth Science Reference Tables to name the New York State cities that have been close to clusters of earthquakes. If a cluster is not close to one city, tell what 2 cities the cluster is between. (For Example: “between Elmira and Binghamton” or “near Binghamton”)

3. Compare the locations of the earthquakes you plotted to the locations of the faults and fractures shown on the same map?

4. Figure 4 shows the locations and magnitudes for earthquakes recorded between 1975 and 1987. Compare the locations of this greater number of earthquakes with the earthquakes you plotted in the map of New York State.

5. Compare the locations of the faults and features shown on the map of New York State with the locations of earthquakes shown in Figure 4.

6. What landscape regions of New York State have the greatest amount of seismic activity? [HINT – see the Landscape Regions map in your Earth Science Reference Tables.]

7. How intensely was the Cornwall-Massena earthquake felt in the Olean area? [HINT – Use the map in Figure 3 and the earthquake magnitude and intensity scales in Figure 2 to help answer this question.]

8. Is the seismic risk for the areas affected by this earthquake different today from what it was in 1944 when the earthquake struck? [HINT – Use the map in Figure 3 and the earthquake magnitude and intensity scales in Figure 2 to help answer this question.]

9. In March, 1994, there was an earthquake about 30 miles southwest of Rochester and 30 miles west of Buffalo. Put a colored star at 430N and 780W to represent this earthquake. According to your map of New York Structure-Seismic Patterns, why should that earthquake not be surprising?
