Nuku'alofa / Moderate shaking (MMI V)
Nuku'alofa (Tonga, 28 km E of epicenter) : Nothing much, just saw the walls (well, the house in general) shaking for a while (a loooong while when you're in that mini-shock state of mind). Scary, but otherwise ok, since everyone else is fine. Nothing will ever compare to the 2006 one though. Just hoping the rest of the neighborhood and family are ok, and there won't be a tsunami pleeeeeaaase (reported through EMSC)  
Nuku'alofa (Tonga, 52 km NE of epicenter) : bit of a shock. woke me up from sleep. seemed strong with big rocking motion. (reported through EMSC)  
Nuku'alofa (Tonga, 52 km NE of epicenter) : We are currently have cyclone warning and the wind and raining is very strong and heavy (reported through EMSC)
