Right in the Ring of Fire. Good thing Chile is a lot more prepared for these sorts of events than other countries down there or these would be a lot worse.

I was in Chile a couple of years ago. It is amazing how little historical architecture remains, especially in Santiago, most of it has been knocked down or condemned by earthquakes over the years, and replaced by extremely modern earthquake-proof buildings.

EDIT: Sorry, to give my post an actual point. It was interesting to see what a city looked like that had to deal with constant earthquakes, and seismic disruption, unlike say, Vancouver.

The West Coast of South America must be especially at risk?

The continent rises straight up from the Pacific to the peaks of the Andes. Not much of a shelf.

https://en.wikipedia.org/wiki/Continental_shelf

The width of the continental shelf varies considerably – it is not uncommon for an area to have virtually no shelf at all, particularly where the forward edge of an advancing oceanic plate dives beneath continental crust in an offshore subduction zone such as off the coast of Chile

https://en.wikipedia.org/wiki/Subduction

Nine out of the ten largest earthquakes to occur in the last century were subduction zone events. This includes the 1960 Great Chilean Earthquake, which at M 9.5 was the largest earthquake ever recorded
