Link What will happen if a big one hits? I have to wonder how much this problem is going to cost me as a taxpayer???

If the shaking cause problems I'm sure they will cry for aid. You deny that they problem exists?

We all live in the same country, if you don't like helping your neighbors leave. |

Earthquakes occur in response to forces, which build up over long time periods, and occur when two bodies of rock slide past each other. This slip can be large for big earthquakes (10’s of meters) or as small as a millimeter. Earthquakes generally occur on pre-existing weaknesses in the rocks called faults. By far, the majority of the world’s earthquakes occur on or near the boundaries of tectonic plates. Large earthquakes tend to be concentrated at plate tectonic boundaries where forces and faults are much larger. Generally away from plate boundary settings, such as Oklahoma, earthquakes will be smaller with magnitudes generally less than 6.5. Small earthquakes (magnitudes 5 or less) occur nearly everywhere in the world. These types of earthquakes can cause damage and loss of life, but damage is usually moderate and closely concentrated around the epicenter, where the earthquake occurred. Oklahoma earthquakes generally occur at shallow depths ranging from about 5 to 15 kilometers (3-10 miles) depth. Oklahoma has a great number of faults of varying sizes, but they are not expected to have very large earthquakes. The Meers fault in Southwestern Oklahoma had an earthquake about 1,200 years ago, which ruptured to the surface and had about 3 to 5 m of slip. Earthquake hazard is the unavoidable risk that an earthquake will disrupt daily activities or cause loss of property or life. Most damage associated with earthquakes is caused by waves generated during the earthquake. Estimates can be made for the chances of how much shaking will occur due to all possible earthquake sources. These estimates use recorded earthquakes and mapped faults to define possible sources and how often these earthquakes occur. Oklahoma has a greater earthquake hazard than the rest of the mid-continent, but the hazard is still less than that for the New Madrid Seismic Zone to the east or the North America-Pacific plate boundary of the Western US. http://www.ogs.ou.edu/level3-earthquakehazardT.php |

Dr. Bryan Tapp is a structural geologist at the University of Tulsa; basically he studies how rocks move beneath the earth's crust. He says Oklahoma has small earthquakes every day. "We are still under a region that is trying to shift, but it is relatively slow," said Dr. Bryan Tapp, Ph.D. Dr. Tapp says you can blame this on events that first happened 300 million years ago. He says when the Wichita, Arbuckle, and Ouachita Mountains were formed, the ground rose up. But just north of the Wichita and Ouachita Mountains the ground sunk and formed the Anadarko and Arkoma basins. This action caused a fault line to form between the two basins, that fault line is where the epicenter to these large earthquakes is located. He says the earth is still trying to relieve pressure from those long ago geologic events. "So we just seem to be relaxing, just slightly, over time," he said. One thing he's positive of: this mess was not caused by fracking. "There's no way that this particular fault or this particular earthquake could have been activated by oil field activity; there's just no evidence of that," said Dr. Bryan Tapp, a structural geologist. Dr. Tapp says we can expect some more earthquakes in the future but probably around the magnitude 3 range. He would be surprised if we see another over five and is confident that we are not gearing up for the "big one." http://www.newson6.com/story/15971637/tulsa-geologist-takes-mystery-from-oklahoma-earthquakes |

You in an area where you feel any of them? If your posts are true then why is there an insurance moritorium rule for earthquake insurance in Oklahoma and why is it being used to curtail insurance? |

Fracking is the cause. Seriously though wasnt there a big quake in the midwest a couple hundred years ago? Living in Vancouver we always take out earthquake coverage. It almost doubles the premium. |

Earthquake coverage is cheap here. Of course, there's almost no fracking around Calgary.
