A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, storms, rain, hail, wildfire, waves, wind, snow, weather and other geologic processes.

Earthquake - tremors and vibrations of the earth's surface. According to modern views, earthquakes reflect the process of geological transformation of the planet. It is believed that the root cause of earthquakes is global geological and tectonic forces, but their nature is currently not entirely clear. The appearance of these forces is associated with temperature drops in the bowels of the Earth. Most earthquakes occur at the edges of tectonic plates. It is noticed that over the past two centuries, strong earthquakes have arisen as a result of ripping open large faults that come out to the surface.

More than a million earthquakes are recorded annually by instruments. The growth in the number of observation points and the improvement of instruments for recording seismic vibrations have made it possible to register more and more earthquakes occurring in the bowels of the planet every decade. If in the early 1900s about 40 earthquakes of magnitude 7 and higher were recorded, then by the 21st century the location and strength of all earthquakes of such magnitude were recorded, and the number of such events amounted to more than 4,000 cases per decade. Depending on the energy of earthquakes, they are conventionally subdivided into strong, weak and microearthquakes.

Vibrations from earthquakes are transmitted as seismic waves. Earthquakes and related phenomena are studied by seismology, which conducts research in the following main areas:

Study of the nature of earthquakes: why, how and where they occur.
Application of knowledge about earthquakes for protection against them by predicting possible seismic shocks in one place or another in order to build structures and structures resistant to their impact.
Study of the structure of the earth's interior and exploration of mineral deposits using seismic waves from earthquakes and artificial seismic sources
