It woke me up in Frederick, which is 15-20 miles from the epicenter. First thing that popped in my mind was our water heater exploded, thought for a second and said it was too "quiet" to be in the house. Then figured a power transformer nearby exploded and when back to sleep. Woke up to the news that it was a 3.6 quake. Didn't realize there was a fault line in that part of the region (I know there is one over near Columbia)...
