A earthquake is a shaking of the earths crust and is a geological phenomenon . Earthquakes can cause intense vibration of the ground, soil liquefaction, and distortion of the ground. Earthquakes can happen almost anywhere but are most common along the boundaries of the tectonic plates. Earthquakes are primarily caused of movement of the tectonic plates. It lasts more than a few seconds.. WHAT DO HURRICANES AND TORNADOES HAVE IN COMMON?. Low Pressure . Strong Winds . Hazardous to Life and Property . HOW DO THEY DIFFER?. Location . Size . Duration .
