Pentagon Quake Nightmare: Fukushima on the Mississippi
By Noah Shachtman
In May, the federal government simulated an earthquake so massive, it killed 100,000 Midwesterners instantly, and forced more than 7 million people out of their homes. At the time, National Level Exercise 11 went largely unnoticed; the scenario seemed too far-fetched — states like Illinois and Missouri are in the middle of a tectonic plate, not at the edge of one. A major quake happens there once every several generations.
But Tuesday’s earthquake along the East Coast is a reminder that disasters can hit where they’re least expected. And if the nightmare scenario comes, government officials worry that state and federal authorities won’t be able to handle the “cascading failures” that follow. The results of May’s disaster exercise won’t be released to the public. But privately, these government officials say they’re glad that this earthquake was just a drill — and not the big one. Especially because there are so many nuclear power plants in the fault zone.
“A couple of things keep me up at night,” Paul Stockton, the Defense Department’s senior homeland security official, told the Aspen Security Forum last month. A quake, like the one simulated in National Level Exercise 11, is chief among the sleep-takers. “It’s so much bigger than anything we’ve faced — way beyond Hurricane Katrina.”
National Level Exercise 11, or NLE 11, was, in essence, a replay of a disaster that happened 200 years earlier. On Dec. 16, 1811, a magnitude 7.7 earthquake hit the New Madrid fault line, which lies on the border region of Illinois, Indiana, Missouri, Arkansas, Kentucky, Tennessee and Mississippi. It’s by far the largest earthquake ever to strike the United States east of the Rockies. Up to 129,000 square kilometers [50,000 square miles] were hit with “raised or sunken lands, fissures, sinks, sand blows, and large landslides,” according to the U.S. Geological Service. “Huge waves on the Mississippi River overwhelmed many boats and washed others high onto the shore. High banks caved and collapsed into the river; sand bars and points of islands gave way; whole islands disappeared.” People as far away as New York City were awakened by the shaking.
