The USGS "Did You Feel It?" map is below, showing the latest reports of where the quake was felt, and how strongly.
Though difficult to read, a helicorder (device used to measure ground shaking) just west of Trumann, AR picked up the earthquake. The helicorder plot below is read left to right, top to bottom, with each new line colored alternating colors (green, black, red, blue) and each line representing 15 minutes. The black squiggles circled in yellow began at 3:10pm CDT and indicate the shaking occurring from the Trumann quake. The helicorder readout shown below is operated by the Center for Earthquake Research and Information at the University of Memphis. Click the image for a full size view.
