This is what got the whole blog idea started. EarthScope gave us a call and wanted to know if we would be willing to be a host site for a seismograph. It was installed and transmitting by July 19, 2012.
This is an example of the data. Look at the wide green trace to the right of 8:00. That was a small earthquake in Arkansas… If you look to the right of the blue 14:00 mark, you will see a double sided comb pattern with long broken teeth. What caused that?….(See next pic)
Hannah, demonstrating the sensitivity of the Seismograph. She jumped each minute to see if the seismograph picked it up…..YEP!
