澳洲大堡礁附近海床正在崩塌 恐引發大海嘯

  澳洲東北面大堡礁的海床絕對會崩解,到時候它會下陷1公里至毗鄰的海底盆地。這將引發地區海嘯,會對約70公里外的昆士蘭海岸線造成衝擊。

  於太平洋地震環附近,連月來頻密地出現6級以上的地震。雖然海床崩塌時間只是估計,但鄰近地區的地震會否更輕易引起這個巨大海床崩塌?真的不能輕視!

  近日多了很多災難預測,都是與近期發表的Webbot(或Web Bot)有直接的關係。

大堡礁附近海床正在崩塌 恐引發大海嘯   20121221

  研究人員告誡稱,昆州北部一塊巨大的海床正處於崩塌的早期狀態之中,一旦真的崩塌,將有可能引發巨大的海嘯,並在一個小時內到達澳洲大陸。

  這塊名為Noggin Block、面積為1立方公里的海洋板塊是古代一次水下滑坡的殘餘物,正位於大陸架的邊緣。研究人員在繪製大堡礁海床地圖時發現了它。

  James Cook University的海洋生物學家Robin Beaman稱,這塊板塊最終將脫離大堡礁,屆時,它將引發一場巨大的海嘯。Beaman在接受ABC的採訪時稱,「它位於水下350處的大陸坡頂端。那是一塊相當大的海床,目前正在非常緩慢地脫離大堡礁的邊緣,不過這一過程仍處於脫離的早期階段。如果它突然發生脫離,那麼這一過程將會非常地迅速,屆時將會引發一場海嘯。這場海嘯將穿越距離大陸70公里的大堡礁,並影響到北昆州地區。」

  根據估計,這場海嘯只需一個小時就能抵達諸如Mourilyan HarbourClump Point一類的沿海地區。

  不過Beaman補充說,目前這塊海床還非常地穩固,只有周邊地區發生非常大的地震,才會觸發它的驟然崩塌。「雖然目前看起來不太可能發生這樣的事,但我們必須瞭解存在這種可能性。我們並不知道它何時會崩塌。我現在只能說,這是必然會發生的事。」

Unstable sea slab near Barrier Reef could cause monster tsunami in north Queensland
December 21, 2012

AN ENORMOUS slab of sea floor is in the early stages of collapse off north Queensland, and could generate a tsunami when it finally breaks off, researchers warn.

The one cubic kilometre slab - dubbed the Noggin Block - is the remains of an ancient underwater landslide, and sits perched on the edge of the continental shelf.

Researchers discovered it while mapping the sea floor around the Great Barrier Reef.
James Cook University marine biologist Robin Beaman says the slab will eventually break away from the Great Barrier Reef and when that happens it could generate a huge tsunami.

"It's actually up on the top of the continental slope in about 350 metres of water,'' Dr Beaman told ABC radio.

"It's a pretty big chunk of sea floor (and) is in the very slow, early stages of starting to break away from the edge of the Great Barrier Reef.

"If it were to break away catastrophically, that is break away really quickly ... it would actually cause a tsunami.

"That tsunami would travel across the Great Barrier Reef, it's about 70 kilometres offshore, and it would impact the local area, the North Queensland area.''

It's estimated it would take about an hour for any tsunami to hit coastal areas such as Mourilyan Harbour and Clump Point, south of Cairns.

But Dr Beaman says it's still very stable, and something like a very large earthquake near the site would be needed to trigger a catastrophic collapse any time soon.

"That is very unlikely. But we should be aware that these things exist. We don't really know when such a block might collapse. All I can say is sometime it eventually will.''

  4. 哇香港鄰近澳洲,真的務必要警醒每一天,作好預備!!
    而且更重要是人生在世能找尋至寶就是基督,得著永恆的生命!!
    災難中犧牲並不可怕,最可怕是你在災難犧牲後面見神時才發現自己未預備好,因那是永恆的災難!!
