What caused the Chile tsunami 1960?
Both the 1960 Chile earthquake and the 1700 Cascadia earthquake were caused by sudden ruptures of long segments of subduction zones. Each of these quakes generated a tsunami that not only struck nearby coastal areas but also caused damage in coastal areas as far away as Japan.
How did Chile respond to the 1960 earthquake?
After being hit by the planet’s largest-ever recorded earthquake back in 1960, Chile developed strict anti-seismic building codes. Strong columns and weak beams meant buildings would have a better chance of swaying with the tremors and avoiding collapse.
How many people died from the tsunami in Chile?

Why are there so many earthquakes in Chile?
Why does Chile have so many earthquakes? Chile is a hotspot for earthquakes because the Nazca plate, a tectonic plate which moves eastwards with a rate of 6.6 cm per year, collides with the South American plate off the Chilean coast. Land was violently shifted up or down several meters, fundamentally changing the Chilean landscape.
