2015考研英语阅读地震学与海啸

　　An energy-release rate indicating a rupture rate of 1?km a second or less sets the alarmbells ringing, for the earthquake has probably spawned a tsunami.

　　岩层断裂速度达1.5km/秒以下的能量释放速度将会拉响警报，而这时极有可能引发海啸。

　　though the system is also sensitive to the actual earthquake magnitude, and adjustsaccordingly, so it did not miss the tsunami-creating potential of the Japanese earthquakeeither.

　　尽管如此，该系统也能检测出地震级数并作出相应调整，因此也检测出了日本地震会引发海啸的风险。

　　The two researchers tried their invention out last year and analysed a great many quakes,including one of magnitude 7.8 that happened on October 25th in western Indonesia.

　　两位研究者去年对该发明进行了测试，用以分析了许多地震，包括去年10月25日印尼西部发生的里氏7.8级地震。

　　The epicentre was 70km from the Mentawai islands, and the quake was felt there onlyweakly.

　　震中位于距民大威群岛70km处，岛上只有轻微震感。

　　But it still raised a devastating tsunami that killed more than 400 islanders.

　　但是，地震随后引发了一次破坏力极强的海啸，导致400多位岛民死亡。

　　The system quickly detected this quake and the two researchers reported recently inGeophysical Research Letters that it automatically identified the tsunami threat 8?minutes after the earthquake began.
