Variations

Examples of datasets that can be investigated with the techniques of this chapter include: stream flow conditions, global land and sea surface temperatures, and many others with latitude and longitude coordinates, such as those gathered with a GPS. Specifically, data from the EET chapters Exploring Regional Differences in Climate Change and Using GLOBE Data to Investigate the Earth System can be brought into AEJEE using the same procedures as in Parts 1 and 2 of this chapter.

Instead of limiting the data to the high magnitude earthquakes, one could investigate the low magnitude earthquakes.

Consider investigating other relationships in the earthquake data. Some questions to investigate might include:

  • Where are really deep earthquakes located? Where are really shallow earthquakes located? Is there a relationship between depth and plate boundaries?
  • Is there a relationship between the magnitude of an earthquake and its depth?

Other Data

On May 12, 2008 a magnitude 7.9 earthquake struck near the city of Chengdu, China. Below are files and links that can be used to explore this event.

  • This file contains just the 7.9 magnitude earthquake.
