全球最大活火山突然喷发，“末日”景象降临夏威夷

　　导读：

　　从上周开始，美国冒纳罗亚火山已连续喷发长达一周时间，至今仍未有减弱迹象。冒纳罗亚位于夏威夷群岛，是世界上最大的活火山，而它上一次喷发还是在1984年。目前冒纳罗亚火山情况如何？此次喷发会带来哪些影响？

　　冒纳罗亚火山喷发：这座世界上最大的火山现在内部怎么样了？

　　Mauna Loa - the world's largest active volcano - is erupting for the first time since 1984. Lava is flowing down the side of the volcano at a temperature of 1,000C, but experts say this does not yet pose a big threat to local inhabitants.

　　世界上最大的活火山冒纳罗亚火山正在喷发中，这是自1984年以来的第一次。熔岩沿着火山向外涌出，温度高达1000摄氏度。但专家表示，当前态势还不会对当地居民构成威胁。

　　Mauna Loa, which means "long mountain" in Hawaiian, is the largest active volcano in the world. It covers 5,271 sq km, and is one of a chain of five volcanoes which form Hawaii's Big Island. This one volcano alone comprises half of the whole island.

　　“冒纳罗亚”在夏威夷语中意为“绵延的山脉”。这座火山是世界上最大的活火山，覆盖面积达5271平方公里，它是构成夏威夷大岛的五座火山之一，占据了整个大岛一半的面积。

　　Mauna Loa's summit is 4,170m above sea level, but its base is on the sea floor. From there to the summit is 9,170m.

　　冒纳罗亚火山海拔4170米，它的基底深藏在海底，而从海底到山顶的高度有9170米。

　　Plumes of super-heated material called magma have been welling up underneath Mauna Loa and neighbouring volcanoes from a "hotspot" deep within the Earth.

　　一股股超热物质从冒纳罗亚及临近火山下喷涌而出，这种物质被称为“岩浆”，它来自地球内部深处的“热点”。

　　

　　Mauna Loa has erupted 33 times since 1843, the date of the first recorded eruption. On average, that it is one eruption every five and a half years. However, the last eruption was almost 40 years ago. The current eruption on Mauna Loa is giving a new generation of scientists the chance to study how the volcano works.

　　冒纳罗亚火山第一次有记载的喷发是在1843年，至今已喷发了33次，平均下来，每5.5年就会发生一次。不过，这座火山上一次喷发还是在大约40年前，而这次喷发会让新一代科学家有机会去研究火山的运行原理。
