介绍:
20160530：Volcanoes 火山
HarounTazieff, the Polish scientist, has spent his lifetime studying active volcanoes
and deep caves in all parts of the world. In 1948, he went to Lake Kivu in the Congo to
observe a new volcano which he later named Kituro. Tazieff was able to set up his camp
very close to the volcano while it was erupting violently. Though he managed to take a
number of brilliant photographs, he could not stay near the volcano for very long. He
noticed that a river of liquid rock was coming towards him. It threatened to surround him completely,but Tazieff managed to escape just in time. He waited until the volcano became
quiet and he was able to return two days later. This time, he managed to climb into the
mouth of Kituro so that he could take photographs and measure temperatures. Tazieff has
often risked his life in this way. He has been able to tell us more about active volcanoes
than any man alive.
