  2. Only one moderate quake and an aftershock by Somegeek · · Score: 5, Informative

    The summary makes it seem like there have been two different big quakes. In actuality there was a moderate 5.2 followed by what is apparently a 4.6 aftershock.

  3. New Madrid fault line by jonfr · · Score: 4, Informative

    The main earthquake and the aftershock are on an fault line known as the New Madrid fault line. This fault line is known for making earthquakes up to 8 on the ricther scale. Last time that did happen was in the 19th century.

    I am fairly sure that this event now is part of normal movement of the fault line, due to happen every 20 to 50 years.

    People in the area should expect aftershocks in the next one or two weeks, maybe longer. Btu the aftershock pattern depends on many factors that I don't know all.

    For those interested the waveform of the earthquake was recorded by people interested in recording earthquakes in nearby states. The plots can be seen here, http://www.simnet.is/jonfr500/earthquake/othersten.htm

    But I have collected them into one nice web page. The data is near real time and is updated every 5 min, at least that is the case for most of the plots
