If 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…
In all, 203,186 earthquakes are marked on the map, which is current through 2003. And it reveals the story of plate tectonics itself.
Beautiful work – illustrating scientific knowledge, history.
