The Gadget Behind Measuring Earthquakes - Measuring The World

#Earthquake #Seismographs #EarthquakeMeasurement Every time an earthquake strikes, we get information about its magnitude, epicenter and intensity. It takes less than 10 minutes for seismologists to calculate them. Incredible, isn't it? This would be impossible without seismographs. These gadgets are extremely sensitive to quakes occurring in any part of the world. Think of seismographs as agents spying on Earth’s movements. The moment this device senses a sudden burst of energy -- courtesy of a quake -- coming its way, it gathers crucial evidence, which helps seismologists track down the magnitude, epicenter and other essential parameters. How did this earthquake measuring device come to be? And how does it work? Find out in this video. The magnitude of the Nepal Earthquake was 7.8.
