There has been a flurry of geological activity in South Carolina lately, particularly around the Midlands and Upstate. In fact, the most recent was a  1.6 magnitude earthquake recorded April 4 near the town of Cross Anchor in Spartanburg County.In this episode of Earthly, Jonathan talks to Clemson assistant professor Brady Flinchum about South Carolina earthquakes and if all the little quakes we’ve been having mean there’s a big one headed our way. Flinchum compares earthquake magnitude to pasta noodles, explains what earthquakes can tell us about the structure of the earth, and even talks about what Marsquakes can teach us about Mars. He also tells us what to do if an earthquake strikes.
