Now I am confused whether I woke up 5 minutes before the quake. The quake was at 4:37, not 3:37 Central Daylight time. But, our weather radio clock is still on Central Standard time. I think the clock said 3:36 or 3:38, but that would be 4:36 in Daylight time. As I said before, it is 4 minutes fast (OK, is 56 minutes slow).
Local news says that people were woken in our county. I wonder if this was mostly in the soft Missouri River floodplain and other areas of young sediment.
