Detailed explanation-1: -The first main earthquake hazard (danger) is the effect of ground shaking. Buildings can be damaged by the shaking itself or by the ground beneath them settling to a different level than it was before the earthquake (subsidence).
Detailed explanation-2: -The greatest danger from falling debris is just outside doorways and close to outer walls of buildings. Go to an open area away from trees, telephone poles, and buildings. Once in the open, get down low and stay there until the shaking stops.
Detailed explanation-3: -Earthquakes can result in the ground shaking, soil liquefaction, landslides, fissures, avalanches, fires and tsunamis.
Detailed explanation-4: -Ground shaking is the vibration of the ground during an earthquake. The shaking triggers other hazards such as liquefaction and landslides. Most earthquake damage results from the seismic waves passing beneath buildings, roads, and other structures.
