Earthquake

An earthquake is a violent and rapid shaking of the ground. It causes oscillations that cause different shocks to buildings: older buildings or buildings planned without anti-seismic criteria may not withstand these oscillations, representing a danger to people.
Earthquakes are well known, although it is not yet possible to predict with certainty when, how strong and where they will occur.
Knowledge of the seismic zone you live in and how your home is built allows you to deal with earthquakes with awareness, reducing the effects.
