1.	How is the magnitude of the earthquake-related to the collapse of houses.
Answer» Through a seismogram, a graph showing movement of seismic waves (seismograph) can be generated. After studying this graph, the magnitude of the earthquake is known. The magnitude of the earthquake is measured with the help of a richter scale. It is because of the primary waves that the buildings on the Earth’s surface move back and forth. The buildings on the Earth’s surface move up and down because of the secondary waves. These are more destructive than the T’ waves leading to collapse of buildings.
