EARTHQUAKES IN THE ILLINOIS BASIN - OZARK DOME REGION
| Quote From Source: | This large region borders the much more seismically active New Madrid seismic zone on the seismic zone's north and west. The Illinois basin - Ozark dome region covers parts of Indiana, Kentucky, Illinois, Missouri, and Arkansas and stretches from Indianapolis and St. Louis to Memphis. Moderately frequent earthquakes occur at irregular intervals throughout the region. The largest historical earthquake in the region (magnitude 5.4) damaged southern Illinois in 1968. Moderately damaging earthquakes strike somewhere in the region each decade or two, and smaller earthquakes are felt about once or twice a year. In addition, geologists have found evidence of eight or more prehistoric earthquakes over the last 25,000 years that were much larger than any observed historically in the region.

And my grandma, Aunts, cousins live right by Olney. |

Geez. I think we just had another one. I could feel the house shaking. Happened around 11:15am.

The site lists five quakes in the area. Two of which were felt.

Were the aftershocks centered in the same area? |

Even Bigger Quake Could Hit Midwest
| Quote From Source: | The magnitude 5.2 earthquake that rocked the Midwest on Friday was felt from Kansas to Georgia, and aftershocks could continue for months at this strange seismic zone at the nation's center and even trigger another big quake, a geophysicist said.
The quake occurred on a northern extension of the New Madrid fault, about 6 miles north of Mt. Carmel, Ill. The New Madrid fault was responsible for devastating quakes in the Mississippi Valley in 1811 and 1812. So the Friday quake and its aftershocks likely are raising the blood pressure of some residents and scientists.
For decades, scientists have debated whether and when the underlying fault could generate another temblor of similar and deadly strength.
"I think we saw a window to this possibility today in the Wabash Valley," said geophysicist Allessandro Forte of the Université du Québec à Montréal, who has studied the region's seismicity. "It's to the north of the New Madrid seismic zone, but given the strength of crust, the stress can be distributed great distances. It's not clear if we could see something in the next few years or even next few months, I would say."

I'm reading up on disaster estimates if the big one like 1811-1812 were to happen again and I see something interesting. It looks to me as if insurance companies are gouging people when it comes to earthquake coverage.
The story I am looking at details the worst case scenario for Louisville, KY where a model estimates $161 million in damages. This is for a quake that hasn't happened in almost 200 years. However when it comes to premiums the story states...
| Quote From Source: |
Premiums for earthquake insurance in Kentucky grew from $25.84 million in 2002 to $35.72 million in 2006, a 38.2 percent increase, according to data compiled by the American Insurance Association in Washington, D.C. From 2005, when $31.49 million in premiums were recorded, through 2006, premiums increased 13.4 percent.

Source URL: http://www.bizjournals.com/l...008/04/21/focus1.html?page=2
That means from 2002 through the end of 2008 the insurance companies (based on the low amount of $25.84 mil per year) would have collected $180 million in premiums for Kentucky. How much have they paid out in that time? $1 million? $2 million? In that short period of time they have already collected enough in premiums to completely cover the cost of the worst case scenario for Louisville. This is in just 7 years. What about the 7 years prior? Or the next seven years?
Do you feel sorry for the insurance companies now? They are charging enough to ensure a nice profit even if the worst case scenario were to happen. That means if it never happens they will continue to make obscene profits on earthquake coverage. $180 million in revenue on maybe $2 million in claims?
I assure if the big one were to happen the insurance companies would fail. First off I doubt they've kept that money in reserve. Surely not enough of it to cover the claims. Also I believe their model is forecasting well short of what damages would really be if the big one did happen again. You will be looking at another Katrina. Instead of loses being $161 million I am guessing it would be closer to $50 to $100 billion for the Louisville metro area. You would be looking at the write-off of nearly every structure in the area.
This is where the similarities to Katrina end. If the damage were limited to Louisville it would be ok to make the Katrina comparison. But in reality it will be far worse. You are looking at the possibility of the destruction of Louisville, Nashville, Memphis, Indianapolis and Little Rock. Not to mention all the smaller cities and towns that dot the map in between these locations.
Insurance companies will fold. That payout you get for damages will likely be no good. If the big quake happens all the quake coverage in the world won't matter. Who is going to repair your place? Think your house will be fixed any time soon? When in the line of a million other homes will yours fall? Will there even be power to drive the tools that do the work? Will the bridges be intact so work crews can even reach you? Where will you buy your food? Or your gas?
To me this is simple. If the events of 1811 to 1812 repeat we will be in a great depression.

Well to add to the devistation most of the structures in this area of the world, at least in rural areas, are 100's of years old.
In a town around the epicenter of the last quake they refer to a house built 40 years ago as "the new house". In vast difference to here in Az where everything is new, and a house 40 years old is ancient. They're also now the most soundly built houses, they weren't made to withstand big earthquakes. When you get a big earthquake in that area, you're going to be looking at widespread death. And then you're going to have famine issues, since so much of our food is produced there. |

I felt the 5.2 and the 4.6 ones but not the 4.0 one.
I looked at the usgs.gov sight today and noticed that the New Madrid is making a little noise now. Hopefully it is just in response to ours and is letting off a little steam.
Just in case, I did tell my 10 year old what she needs to do if a 6.0 happens to hit here.
I expect to get sucked up into the sky by tornadoes, but don't expect the ground to move in Indiana, lol. |

At first there was a long list of quakes around Ridgely, TN. This went on for a bit then there was relative quiet. Then we had the big Mount Carmel, IL quake. No more Ridgely quakes. We had a bunch of Bellmont and Mount Carmel quakes (they are about 25 miles apart). Now all the sudden the last two quakes are Ridgely located. These are the first in a couple of weeks for that location. I wonder if there is a connection between all these?
