One of the perils of nature is an earthquake. An earthquake is a natural disaster that occurs when the tectonic plates in the Earth's crust shift suddenly, causing seismic waves. These waves can cause the ground to shake violently, which can lead to damage to buildings, roads, and other structures, as well as to injury or death for people and animals caught in the quake. Earthquakes can also trigger other hazards, such as landslides, tsunamis, and volcanic eruptions. While it is not possible to predict when an earthquake will occur, people can take steps to prepare for them, such as by securing their homes and belongings and having an emergency plan in place.
