Maavärinuid, often referred to as earthquakes, are a natural phenomenon characterized by the sudden shaking of the Earth's surface. These tremors are primarily caused by the rapid release of energy in the Earth's crust, which creates seismic waves that travel through the planet and cause the ground to vibrate. The vast majority of earthquakes occur along fault lines, which are fractures in the Earth's crust where tectonic plates meet and interact. These plates are constantly in motion, and when they get stuck, stress builds up. Eventually, this stress is released in a sudden slip, resulting in an earthquake.

The magnitude of an earthquake is a measure of the energy released, typically quantified using the Richter scale or the moment magnitude scale. Intensity, on the other hand, describes the effects of an earthquake at a particular location, such as the level of shaking and the damage caused. While most earthquakes are minor and go unnoticed, some can be extremely powerful, leading to widespread destruction, loss of life, and significant geological changes like tsunamis and landslides. Predicting the exact time and location of future earthquakes remains a significant challenge for seismologists, although advancements in monitoring and research continue to improve our understanding of seismic activity.
