　　Volcanoes, earthquakes, and tornadoes all can cause enormous damage, and predicting where and when they will strike is of great importance. Volcanologist Dr. Marie Edmonds has devised sensors that monitor the underground activity of magma to better predict future eruptions on the Caribbean island of Monserrat, the site of the massive 1995 eruption captured for this film. Geophysicist Dr. Ross Stein studied the earthquake repair records in Istanbul's Hagia Sophia over the centuries to find clues about the history of earthquakes in Turkey. He discovers a pattern in quakes along the long North Anatolian Fault system, including the massively destructive quake at Izmit in 1999, and predicts the next earthquake just a few miles south of Istanbul. Dr. Joshua Wurman and his team chase tornados in trucks equipped with Doppler radar in an attempt to probe the interior of a tornado just as it is born. 　　译文(2): 火山、地震和龙卷风都能造成巨大的破坏，预测它们将在何时何地发生是非常重要的。火山学家玛丽 · 埃德蒙兹博士设计了监测地下岩浆活动的传感器，以便更好地预测加勒比海岛屿 Monserrat 未来的火山喷发。地球物理学家 Ross Stein 博士研究了伊斯坦布尔圣索菲亚大教堂几个世纪以来的地震修复记录，以寻找土耳其地震历史的线索。他发现了沿着北安那托利亚断层系统的地震模式，包括1999年 Izmit 的大规模破坏性地震，并预测了伊斯坦布尔以南几英里处的下一次地震。约书亚 · 沃曼博士和他的团队开着装有多普勒雷达的卡车追逐龙卷风，试图探测龙卷风刚刚形成时的内部情况。
