Ticuantepe (Nicaragua, 224 km NW of epicenter) : It was pretty long! I felt it lasted forever cuz I was in bed and stayed in there for some seconds to verify it was a shake. I then went to the kitchen and warned my sister. The water fountain was shaking and the lamps were moving from side to side. I went to the garden and the front gates were trembling and the street lamp post was shaking the cables swinging from side to side. The movement was definitely a swinging movement. Awful!! (reported through EMSC)
