When we least expected, when release prepared, disaster can strike and few disasters are as unsettling as an earthquake.

Dr. Allan Lindh: My guess is that earthquakes are really so scary because you don't have any warning. It's the only thing besides a nuclear war that can really one secondyou're living in a big beautiful city in ten seconds later it's flat.

Every day the earth is shaken by hundreds of small earthquakes. Most go unnoticed. They usually occur along the boundaries of the thin plates that cover the earth like an eggshell.driven by the heat deep within the Earth's core the plates grind against each other on long lines called faults.

When the plates find their motion blocked, stress builds up. Finally, the fault gives way. The released energy races through the earth in the form of seismic waves. For much of the world the movement of plates like these is also an indispensable creative force.

Dr. Allan Lindh: If we didn't have earthquakes. If we didn't have this great flow of heat from the interior of the earth. The earth would be a cold dead place. If it wasn't for this great flow of heat there'd be no continents, no oceans, no atmospheres.The earth would be as dead and dry and cold as the moon. It's really the earthquakes that create the topography the valleys the mountains.

Earthquakes have been shaping landscapes for eons. it's only in the last few hundred years that civilization has gotten in the way and when it does...

언제 방류 준비된 재난이 닥칠 수 있고 지진만큼 불안한 재난은 거의 없을 때 우리는 예상하지 못합니다.

지진은 오랫동안 풍경을 형성해 왔습니다. 문명이 방해가 된 것은 지난 몇 백 년 동안 뿐입니다
