I check AgTalk Forums most days before work. Lots of descriptions of how it felt, damage if known as most were posted before 7:00AM CDT. Worst damage noted tonight was cracked foundation and a retaining wall moved 2 inches. I posted the location on USGS to report feeling the quake. I hope some of these folks did. On nice comparison of this one to the 1968 one. Later reports on the aftershocks.
