密西西比谷中部比起落基山脉以东美国的任何其他地方有更多的地震发生,造成这些地震的地质结构深埋在沉积物中。不断深入的地球物理研究正在揭示这些潜藏的构造,使得本地区的居民对未来的地震有更好的准备。1811～1812年的冬天对于密西西比谷的欧洲定居者来说是极其困难的。当肖尼人族长、空想家Tecumseh正在试图联合这个
The Central Mississippi has more earthquakes than any other part of the United States to the east of the Rockies, causing the geological structure of these earthquakes to sink deep into the sediments. Continuing geophysical research is unraveling these hidden structures and enabling residents in the region to better prepare for future earthquakes. The winter of 1811-1812 was extremely difficult for the European settlers in the Mississippi Valley. As Shawnee patriarch, visionary Tecumseh is trying to unite this one
