Hello friend, I watched a video explaining how the falling of a water drop can be compared to an earthquake. A falling drop transfers its potential energy formed by the accumulating water into the pool, where it travels in all directions outwards, and there are unseen compressional waves (Hubenthal, n.d.). Similarly, the movement of the earth’s tectonic plates leads to the accumulation of potential energy in rocks, and increased accumulation makes the strain too much, causing the rocks to break, and the potential energy gets converted into kinetic energy. An earthquake occurs after the release of the stored energy, and it travels in all
