Fairhope, AL (1701.3 km NNE of epicenter) [Map] / not felt : I heard distant rumblings for about a 20 minute period. Numerous people with 125 mile radius from me were also on Facebook commenting about the sound. It was like distant thunder (nothing in radar) or like sounds you hear during construction
