To the best of your ability, use a colored pencil to draw and lightly shade in the approximate location of the seismic zone named in question 3. Be sure to label the seismic zone on the map.

Brainstorming:

Assume that the same earthquake occurred, but the seismic station in Los Angeles malfunctioned, and did not record the earthquake. With only the information from seismic stations in St. Louis and Houston, brainstorm how a geologist might determine the location of the earthquake epicenter?
