We picked this quake up strongly on our AS-1, but now it has been
deleted by the USGS. Why would this be?

    I got my answer - the local time was incorrect. There is a new
    corrected page.

    Hi Cris and all IRIS, I, too, had great trace images of the EQ and after shock. I was lecturing about 70 people when the aftershock came through. The small stuffed objects suspended on a wire across the top of my classroom (all 29 of them) swayed in harmonic motion. It was great! Two local TV stations showed up to come film. They already know I have the seismograph in my classroom so I don't have to call them anymore.

    Thank you to IRIS for the great educational experience for the children and the positive PR in the community.

    Really? I just looked at recent earthquakes at the USGS site and it is there.

    As it was felt by people in the Grand Rapids area - and some in our county, I sent an image of our station's seismogram to Channel 13 in Grand Rapids. They used it in their web-based story on the quake and came up to do some filming as I did a lesson relating to the quake with one of my classes.

    It was great to see the amount of coverage the science behind earthquakes got. They aired versions of the story using this footage at 6, 11 yesterday and 7:30 this morning.

    It was ironic that our "local" station out of Cadillac did not even respond to my e-mail.

    Now if I can just get my school to let me past the firewall again and get my station back on the IRIS site......

    I have a question: why is the media reporting the quake's epicenter in Illinois, while IRIS ha it Indiana? I know they're border states and all, but why the confusion? Or am I the only one confused?!

      For once, the media got it right! The earthquake is centered just west
      of Mt. Carmel, Illinois, and most of the damage was centered in a 10-20
      mile radius around that area. The location is indeed close to the
      Indiana border, and though we'd like to claim it as "The Great Indiana
      Earthquake of '08", it clearly belongs to our neighbors across the
      Wabash River. We're in the process of deploying portable seismographs
      and GPS instruments to see if we can track the surface deformation and
      aftershocks associated with this interesting event.

      Thanks for the question!

        IRIS showed the location name (but not the map location) to be in
        Indiana due to the way an automatic algorithm comes up with the place
        name. It was so close to the border that a rounding error caused the
        wrong state name to be used. It has now been corrected.
