00:00:00.350 --> 00:00:04.748
A couple of things that we need to bear in mind when we talk about an earthquake like this:
談及像這樣的地震，首先有幾件事情必須記在心裡：

2
00:00:04.995 --> 00:00:09.212
if the terrain were rocky like in Chile, the shaking is not that intense.
如果是像智利那樣的多岩地形，搖動就不會那麼強烈。

3
00:00:09.212 --> 00:00:18.424
But when the terrain is sandy, and that's the case of Christchurch, you know, the ground shakes violently because it is softer.
但如果是像基督城那樣的沙質地形，由於地層較軟，搖動就會非常劇烈。

4
00:00:18.538 --> 00:00:19.620
It's like Haiti.
海地也是這樣的情形。

5
00:00:19.960 --> 00:00:21.875
And in this case, you know, you say,
在這種狀況下，你也許會問：

6
00:00:22.416 --> 00:00:26.820
"6.3 and all this damage? What's going on?"
「地震規模六點三竟然會造成這麼嚴重的損害？到底怎麼了？」

7
00:00:27.194 --> 00:00:33.410
Well, we need to take into account depth, and it's only five kilometers deep.
我們必須把地震深度考量進來，而海地的地震只有五公里深。

8
00:00:33.410 --> 00:00:35.532
We're talking about the 6.3.
這是規模六點三的地震。

9
00:00:35.935 --> 00:00:42.922
So this graphic illustrates what happens when the earthquake is shallow like the one in New Zealand today.
這張圖顯示了像紐西蘭今天發生的淺層地震會造成什麼樣的後果。

10
00:00:43.122 --> 00:00:45.997
Then we see the shaking more severely on the ground.
我們可以看到地面上的搖動比較嚴重。

11
00:00:45.997 --> 00:00:55.591
That's why the 6.3 doesn't seem to be that intense, but when we take into account the depth, it has been.
這就是為什麼規模六點三的地震看起來似乎沒有那麼強烈，可是一旦把地震深度考慮進去，強度就變得相當驚人。

12
00:00:55.689 --> 00:00:58.411
And also, and this is perhaps more importantly,
此外，更重要的一點是，

13
00:00:58.721 --> 00:01:03.680
is that New Zealand is right in between the Australian Plate and the Pacific Plate,
紐西蘭正位於澳洲板塊與太平洋板塊之間，

14
00:01:03.720 --> 00:01:07.115
so that's when the ground shakes to accommodate.
所以地層會在板塊的壓力下搖動。

15
00:01:07.142 --> 00:01:10.565
So when we have an earthquake, there's movement of these plates.
地震一旦發生，這些板塊就會出現移動。

16
00:01:10.569 --> 00:01:18.441
And now we may see aftershocks for months until things go back to sort of settling down again.
在事情平靜下來之前，餘震可能還會持續幾個月之久。

17
00:01:18.772 --> 00:01:29.409
So don't be panicking in case [if] you feel some more shaking on the ground; [it] should be lower than what we have seen so far.
所以，如果你感到地面出現更多搖動，不必驚慌，接下來的震度應該都會比我們目前見到的地震還小。

18
00:01:29.824 --> 00:01:34.793
And finally, the 7.1 on the fourth of September was inside,
最後，九月四日發生的規模七點一地震是在內陸，

19
00:01:34.789 --> 00:01:37.770
not on a sandy foundation -- [a] more rocky area.
不是在沙質地層，而是多岩地區，

20
00:01:37.770 --> 00:01:40.481
That's why the shaking wasn't that violent.
所以搖動沒有那麼劇烈。

21
00:01:40.891 --> 00:01:44.072
So we need to entertain all these aspects.
我們必須考慮所有這些面向。

22
00:01:44.375 --> 00:01:49.945
And remember there are going to be more aftershocks for months now
記住，接下來幾個月還會有更多餘震，

23
00:01:49.991 --> 00:01:53.022
until everything goes back to its normal position.
然後狀況才會恢復正常。
