The New Madrid Quake of 2009
First of a Series
March 4, 2009
The elections were over. We still had troops fighting the War on Terror. The economy was up, or down, or normal depending on who you listened to.
9:42 a.m., CST.
Our world ended with a bang, not a whimper.
From Indianapolis to Little Rock and beyond, the ground began to shake. Then roll, then open and close. The roar was unlike anything ever heard and it went on for what seemed hours but was two minutes and 17 seconds.

The shock wave raced out from the epicenter, reacting with each type of rock or soil it found. The Mississippi River leapt sideways, to the west north of the epicenter and to the east on the southern side of the shock. All along the river, every community built on the bluffs died. Entire towns built on the sediment laid down by the river over a million years shook, and swayed and sank as if they had been built on quicksand. Tens of thousands died during the shock itself and in the moments after.
The worst was yet to come.
Every bridge crossing the Mississippi, the Missouri and the Ohio within a four hundred mile radius went down. Every pipeline, fiber cable, electric line, everything solid that crossed the rivers whether buried or not snapped. The power grid for the entire United States west of the Rockies other than Texas failed. Buildings were damaged as far away as Boston and Charleston, South Carolina. The quake was felt in Montreal and Houston.

At the End of THE DAY
A couple of firefighters, a nurse and an EMT staffed this shelter. Staffed isn't the right word. They had found their way to this bit of open ground, and cobbled together the shelter as the injured began to arrive.
Everyone knew that there had been a quake. No one knew much else. Rumors abounded. California had fallen in to the ocean. The Chinese had nuked St. Louis. Terrorists, no, Mexicans, no, the wrath of a vengeful God.
Some supplies had been scrounged up, and the uninjured were put to work gathering more. It would be a cold night, and no one had yet seen any sign of police or rescue workers. One of the piles of rubble must have had a fur store in it since several volunteers had returned with armfuls of mink and ermine coats. The staff tried to ignore the pockets bulging with jewelry as they put the warm coats to good use.
A couple of old men, vets of the Vietnam War, they claimed, were setting up a latrine arrangement and some teen aged girls were using a table that they had found to put out a buffet of the food that was available.
The babies didn't cry at the aftershocks any more. There had been so many, some almost as bad as the original quake. The little ones were all cried out and the toddlers just sat with a hollow stare in someone's arms.
The sky was full of smoke and dust. All the fires locally had burned themselves out but several tall columns of smoke could be seen in the distance, out by the airport and the industrial park. A dog would bark in the distance, and others would howl a response.
They were getting hungry.
