On a night in May 1751, the earth shook hard enough that, in the words of one chronicler, the residents "could not remain standing."

When the survivors counted what was left, they did not just rebuild. Fourteen years later, they abandoned the spot entirely and carried their city to higher, safer ground inland. The place they left behind keeps its old name in a single surviving word.

1751 Concepción Earthquake: The Fault That Will Not Rest

Photo credit Public domain. The 1751 catastrophe was not bad luck. It was geology doing exactly what it does along this coast.
