A century of earthquakes in one map

Earthquakes with a magnitude of at least 5 are enough to damage buildings, and there were at least 72,000 such events in the last century, writes Nathan Yau at Flowing Data, who created a plainly-readable world map depicting all of them. He provides the code to reproduce his work using USGS data, too, and it's surprisingly short and straightforward: "the dataset linked in the code is just a small sample of what's available."
