Description of the activity/assignment
In this in-class activity, students download earthquake data from the Sumatra area and examine it first in Excel. They quickly observe that, even when they sort the spreadsheet in various ways, they can develop only a limited picture of the data. In the second part of the activity, students bring the data into ArcMap to portray it spatially, and they change the symbols to portray various attributes of the earthquakes. In the final part of the activity, students display the data in three dimensions in ArcScene. This latter is particularly powerful, because students can interactively rotate the ArcScene, which helps immensely in their abilities to visualize the depth distribution of quakes.
Although the activity focuses on Sumatra, the activity could easily be done for any area of the world. Later in the semester in this course, students download earthquake data from other areas in the world when they evaluate earthquake hazards in other regions.
