在美国加利福尼亚的西拉内华达山东坡上,地质学家正在利用一个隐藏的岩浆池进行猫捉老鼠的地震游戏。在1983年1月6日晚,朗瓦利(Long Valley)发生了一系列地震,其中两次分别达到里氏5.5级和5.6级,随后还发生了群发性小地震。从1975年起一直在朗瓦利破火山口进行地震监测的美国地质调查局的专家和其他科学家很快赶到现场。为了弄清破山口内一个起始穹地是否在不断隆起,科学家利用地震仪器进行了观测。如果人们从这里的地震得到错误的情报,那么当
On the eastern slopes of Sierra Nevada in California, USA, geologists are using a hidden magma pool for cat-and-mouse quake games. On the night of January 6, 1983, a series of earthquakes occurred in Long Valley, 5.5 and 5.6 respectively, followed by mass earthquakes. Experts and other scientists from the United States Geological Survey that have been monitoring the earthquakes at the Long Valley caldera since 1975 are soon to arrive. In order to find out if a starting dome in the broken mouth was constantly rising, scientists used seismic instruments to make observations. If people get the wrong information from the earthquake here, then
