Write a short note on measuring earth quake
Answers
Answer:
(CNN) Earthquakes are measured using seismographs, which monitor the seismic waves that travel through the Earth after an earthquake strikes. Scientists used the Richter Scale for many years but now largely follow the "moment magnitude scale," which the U.S. Geological Survey says is a more accurate measure of size.
Three types of waves are produced from the focus during an earthquake:primary waves, secondary waves and surface waves. The surface waves is the most destructive once the seismic waves are recorded by an instrument called sesmography
Explanation:
The Richter scale measures the intensity of energy released at the time of an earthquake. that occurred in Chile has been the most severe one. It recorded an intensity of 9.5 in the Richter scale.
