It's impossible to say definitively which country has had the largest earthquake, as there are a few ways to interpret "largest":

* Magnitude: The largest earthquake ever recorded was a magnitude 9.5 earthquake in Chile on May 22, 1960.

* Area affected: The 2004 Indian Ocean earthquake and tsunami, which occurred off the coast of Sumatra, Indonesia, affected a vast area and caused significant damage and loss of life.

* Number of casualties: The 1556 Shaanxi earthquake in China is estimated to have killed hundreds of thousands of people, making it the deadliest earthquake in history.

So, depending on what metric you use, the answer could be Chile, Indonesia, or China.

It's important to remember that earthquakes are a natural phenomenon that can occur anywhere in the world, and even the largest earthquake may not necessarily be the most destructive.
