    A Christchurch Earthquake Recovery Authority (CERA) spokesman said indicator buildings in Christchurch's red zone experienced a "small amount of movement".

      The Earthquake Commission (EQC) is classifying today's magnitude-5.5 aftershock as a new event for insurance purposes.

      People who have new or worsened damage as a result of the quake will need to lodge a new claim with the EQC by September 6.

        Monday's magnitude-5.5 aftershock was significantly shallower than scientists initially thought.

        The 9.09am quake, the sixth largest since September 4, was centred just east of Rolleston on the tip of the Greendale Fault.

        Initial scientific analysis pinpointed its focus as 15 kilometres deep, which seismologists said explained why it was not felt more strongly around Christchurch.
