RISK EARTHQUAKE the earthquake…! Earthquakes, also known as tremors, are sudden vibrations or oscillations, rapid and more or less powerful, of the earth's crust, caused by the unexpected movement of the rock mass in subsoil. This displacement is generated by tectonics force that cause the release of energy in an internal point of the Earth said hypocenter; starting from the fracture a series of elastic waves, known as "seismic waves", propagate in all directions from the hypocenter, giving rise to phenomenon observed in the surface! HOW TO BEHAVE! I don’t have to rush out, but mostly it is better to put me away from windows and doors with glass that could fall and hurt me! It is better to take shelter under the lintel of a door, near a bearing wall or under a table! I don't use the elevator because I might get stuck in there!
