Yeah, southeastern Nebraska tends to be the most earthquake-prone area in Nebraska; it has something to do with being located right next door to Missouri.
HOWEVER, the biggest earthquake, ever, in the history of Nebraska, took place clear over at the opposite end, in northwestern Nebraska, in 1964.
The Great Merriman Earthquake.
We have a member here who was not only a survivor of that, but also whose home was practically the epicenter of it.
