"I felt it" reports:
Nelson / MMI V (Moderate shaking): We were in social studies class, working on our topic: Natural Disasters. Our teacher had just said \"Natural disaster\" when the room started shaking.

Waikanae / MMI VI (Strong shaking): The ground started with a shake and then it went into a roll like effect and unlike other quakes/last month's 6+ quake it seemed to go quiet like it was going to stop but the rolling increased and then shaking that seemed to go on for a long time before a strong shake. The other difference with this quake compared to the 6+ quake last month was the aftershock in this area was not felt till some time later nearly 45mins later. The aftershock last month was felt in a 15 minute timeframe. Perhaps
