What are the signs that nature is telling us?' Scientists are triggering earthquakes in the Alps to find out what happens before one hits

Scientists in the Alps are deliberately triggering earthquakes in a deep tunnel to understand what happens before natural quakes strike. The FEAR project pumps water into fault lines to reduce friction and cause controlled earthquakes, having already generated hundreds of thousands of tiny quakes up to magnitude zero. By studying these controlled ruptures with thousands of nearby monitors, researchers hope to predict the size and danger of future natural earthquakes on real fault lines.
