What Were the Biggest Earthquakes in History?

10. Valparaiso, Chile (1730) 1 of 11

An 8.7 magnitude quake rocked Valparaiso, Chile in July 8, 1730. While the facts available on the earthquake are limited, sources indicate that the tremors were enough to demolish the beloved parish church, while creating a 8.75 magnitude tsunami. Thankfully, because of a strong foreshock prior to the event, people were able to leave their homes, resulting in few deaths. The same can be said about the strange tide pull before the wave as well.
