WHAT IS AN ????? An earthquake (or quakes, tremors) is shaking of the surface of earth, caused by sudden movement in the Earth's crust. They can be extremely violent. Earthquakes are usually quite brief, but may repeat. They are the result of a sudden release of energy in the Earth's crust.

CAUSES OF AN EATHQUAKE Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little.

DAMAGE CAUSED BY EARTHQUAKE Earthquakes cause direct damage when the seismic disturbance weakens and collapses buildings and other infrastructures not built to withstand the tremors. This often causes great loss of life. Other damage caused by earthquakes results from landslides, mudslides, avalanches, fires, soil liquefaction and tsunamis.

PROTECTING YOURSELF If an earthquake begins :

MORE MEASURES Take cover under a sturdy piece of furniture or seek cover against an interior wall and protect your head and neck with your arms. Avoid danger spots near windows, hanging objects, mirrors, or tall furniture. Hold the position until the ground stops shaking and it is safe to move.
