Earthquakes, natural disasters that can often prove destructive to man, occur in different circumstances and can be of different types. Discover their characteristics with us!
THE TYPES OF EARTHQUAKE
An earthquake can be heaving or undulatory:
- Un trembling earthquake causes a shaking that occurs vertically, therefore from bottom to top, which is mainly felt in the epicentral area;
- Un wave earthquake instead it causes mostly horizontal motion that causes objects and buildings to sway.

Earthquakes can also be classified into other types, including:
- I tectonic earthquakes, which originate from the movements along the faults. They are the most frequent and most powerful, as they release a large amount of energy.
- I volcanic earthquakes, which originate from the volcanic activity of magma in the subsoil or in the volcanic vent. They are less frequent and a lower potency.
- I collapse earthquakes, originating from the collapse of mountains, caves or the fall of landslides. They are infrequent and have a very limited and localized power.
- Finally, the artificial earthquakes, i.e. man-made, which can occur after an explosion.
