Stunning Map Reveals World's Earthquakes Since 1898

f you've ever wondered where — and why — earthquakes happen the most, look no further than a new map, which plots more than a century's worth of nearly every recorded earthquake strong enough to at least rattle the bookshelves.

The map shows earthquakes of magnitude 4.0 or greater since 1898; each is marked in a lightning-bug hue that glows brighter with increasing magnitude.

The overall effect is both beautiful and arresting, revealing the silhouettes of Earth's tectonic boundaries in stark, luminous swarms of color.
