Kopavogur / Weak shaking (MMI III) / vertical swinging (up and down) / 1-2 s : I felt that wave was coming from far, finally came to my place and gone. Probably because of experience those earthquakes every day, I can feel even a 2 seconds before, I can feel wave coming. | 13 users found this interesting.  
  • Se está liberando mucha energía y gran cantidad de ondas lo que debe estar confundiendo la percepción, son muchos sismos sin embargo su comentario parece ser exacto, trenes de onda de distinta altura se perciben así, llegan primero ondas más altas como un fenómeno escalonado
Keflavík / Moderate shaking (MMI V) / horizontal (sideways) swinging / 2-5 s : Keflavík ground floor, whole house swang and could hear a hard hit. Felt like there's no ground under our feet (reminding standing in a boat going through waves) | 12 users found this interesting.
