I'm here in Irving Texas today and have had multiple earthquakes since this afternoon. 3 felt quite strong and then just had some tremors 10 to 15 minutes ago. Looks like this has been happening since September. Anybody traveling in for the convention next week might get a little extra experience than planned.
