幫我翻譯英文please!!!!!!!!!

火山爆發的預測是火山學家最注意的一項。火山爆發時我們無法防止周圍地區的財物損失,但若能在爆發以前預作準備,則可以使許多人免受無妄之災。

一般火山爆發都無法預測,但有一些火山已建立了警報系統,如夏威夷的火山。熔岩進入熔岩庫時,火山本身會有些為膨脹,會發生小地震,周圍溫度逐漸升高,中央噴發口附近有氣體溢出。

科學家用不同的儀器預測火山何時爆發。如用傾斜計測火山膨脹程度;地震儀測量地震;溫度計偵測溫度;氣體追蹤儀測定氣體逸出量。

在岩漿庫中,充滿氣體的岩漿遭受到周圍固體岩塊極大的壓力,壓迫岩漿向岩隙膨脹或熔化周圍軟弱的岩石,最後形成一條通路。岩漿沿著通路往上升,在接近地表時內部的氣體首先釋放而出。因此岩漿夾雜著氣體衝出地表,形成中央噴火口。岩漿及其他火山物質大部分由中央噴火口噴出並在附近堆積,漸漸形成火山。

一般火山爆發停止後,在山頂上形成盆形的坑洞,噴火口便在洞的底部。

火山形成之後,以後上升的岩漿不一定都經由中央噴火口爆發。部分的岩漿會穿過通路側壁的岩隙發展出小叉道。甚至從叉道爆發出來。

    Volcanic eruption prediction is a volcanologist most attention. When we can not prevent the eruption property damage around the area, but if in the past to prepare for the outbreak, you can make a lot of people from unexpected calamities.

    General volcanic eruptions are unpredictable, but there are some volcano warning systems have been established, such as the Hawaiian volcanoes. When lava lava entering the library, some of the volcano itself expands, small earthquakes occur, the ambient temperature is gradually increased, the central vents near gas spill.

    Scientists use different instruments to predict when the volcano erupted. As measured by tilting the volcano swelling degree; earthquake seismograph measurements; thermometer to detect temperature; trace gases measured the amount of gas escaping.

    In magma library full of gas surrounding solid rock magma suffered tremendous pressure to Yanxi expansion or compression of magma molten rock around the weak, the final form of a path. Magma to rise along the path, in the near-surface gas inside the first release out. So magma mixed with the gas out of the ground, forming a central crater. Most of lava and other volcanic material ejected from the central crater and accumulate in the vicinity, and gradually form a volcano.

    Usually stop after a volcanic eruption in the top of the hill forming the basin-shaped crater, then the bottom of the crater in the hole.

    After the volcanic formation, not necessarily after the outbreak of magma rising through the central crater. Magma path will pass through the sidewall portion of Yanxi develop small side road. Even burst out from the side road.
