In 2010, an earthquake killed 222,570 people in Haiti, injuring 300,000 and displacing over a million. In an attempt to discover how to predict earthquakes, these researchers are using machine learning to analyze the acoustic data from tectonic plates.

In 2013, a small meteor exploded above Chelyabinsk, Russia that sent over 1,200 people to the hospital. Now, NASA has plans to detect Earth-bound asteroids and defend the planet from another large-scale catastrophe.
