The tectonic plates that make up the world's crust
構(gòu)成地殼的各個(gè)構(gòu)造板塊
grind against each other,
相互擠壓
building up huge amounts of stress.
逐漸累積起巨大的壓力
The stress produces cracks known as faults.
壓力造成了被稱之為斷層的裂縫
Wherever there's a fault,
有斷層的地方
there might one day be an earthquake.
總有一天會(huì)有地震發(fā)生
We know that earthquakes happen
我們知道地震的發(fā)生
because stress builds up in the crust
是因?yàn)榈貧ぶ兄饾u累積的壓力
and finally you overcome the friction and you slip suddenly.
最終克服了摩擦力 突然釋放
Actually, an analogy is snapping your fingers.
其實(shí) 就好比打響指
When you snap your fingers
當(dāng)你打響指時(shí)
you have two surfaces in frictional contact.
兩個(gè)面接觸摩擦
But, all right, now I'm trying to say
而現(xiàn)在我想說(shuō)明的是
what micro-second they're going to move on
在某一微秒時(shí)手指將會(huì)動(dòng)起來(lái)
and that's going to be exactly
而這恰恰就是
what point the friction is overcome.
摩擦力被克服的那一時(shí)間點(diǎn)
That's,There's a lot of processes going on there.
這其中經(jīng)歷了很多的過(guò)程
But even though scientists know
但即便是科學(xué)家知道
how and where earthquakes happen,
地震形成的原因和發(fā)生地點(diǎn)
the question they can't answer is the one that matters most.
對(duì)最關(guān)鍵的一個(gè)問(wèn)題 卻仍無(wú)法作答

中國(guó)會(huì)發(fā)生一場(chǎng)大地震
No. There's nobody who on May 11th said
不 在5月11日 沒(méi)人說(shuō)過(guò)
there's gonna be an earthquake.
馬上就會(huì)發(fā)生大地震
There are plenty of people on May 13th said
倒是有不少人在5月13日說(shuō)
"I really did know this two days earlier. "
我兩天前就知道 會(huì)有這場(chǎng)地震
It's a far cry from the picture of just couple of decades ago.
這跟幾十年預(yù)測(cè)帕克菲爾德地震那次 是兩回事
