Chile's Most Prominent Hazards

Chile is highly susceptible to many natural hazards, but the two biggest threats are earthquakes and extreme weather, specifically drought. Why they happen & why I'd address them as a priority Earthquakes ThinkHazard says Chile's earthquake hazard is classified as high, meaning there is more than a 20% chance of a potentially-damaging earthquake taking place in the country in the next 50 years. The potential for hazard is particularly high due to its 3,000 km long subduction zone along the coast and because of the relatively high subduction velocity (6-7 cm per year) of the Nazca plate upon which it sits on. To sum it up:1/4 of all global seismic energy released in the past century occurred there . Chile has had 13 major earthquakes in the last 30 years, and boasts the largest earthquake ever recorded (a M 9.5 in Santiago, 1960 - fyi), AND many of these quakes trigger either landslides, tsunamis, and/or volcanic activity. That being said, I think earthquakes would b...
