7.5 Implementing Cluster Analysis: Earthquakes

We have real data describing 500 earthquakes that occurred during a month in late 2022. Given the raw data, it might be difficult to see any type of pattern or similarity in this data set. However, if we extend our cluster analysis technique from the previous section, we might discover some interesting results.
