Question
How is the magnitude of the earthquake related to the collapse of houses?
Solution
- If the magnitude of an earthquake is high, it results in extensive destruction of buildings.
- There are three types of seismic waves: primary waves, secondary waves, and surface waves.
- After the primary waves, the secondary waves reach the Earth's surface. These waves are more destructive than the primary waves.
- The movement of particles in the materials in the path of these waves is longitudinal and vertical relative to the direction of the waves.
- Consequently, buildings on the Earth's surface sway up and down, leading to the collapse of structures.
