Aranui Christchurch / Moderate shaking (MMI V) / horizontal (sideways) swinging / 2-5 s : I was walking and I heard a bang/rumble and I almost lost my balance. | 3 users found this interesting.  
Christchurch, Canterbury (14.2 km W of epicenter) [Map] / Very weak shaking (MMI II) / single vertical bump / very short : Made me look around. Very short. More noise that anything.
