Moderate aftershocks continue to rattle Christchurch earthquake area

Earthquake Report comment :
As predicted before, aftershocks would occur continuously after the massive Darfield earthquake from September 4.
20 minutes ago another moderate M 4.6 aftershock has rattled the Christchurch area.
A lot of 'felt' reports arrived quickly at the GNS Science. People living in the area reported overwhelmingly a MM (Modified Marcalli) value of IV = light to moderate shaking.
As you will be able to see on the Seismograph, aftershocks can be very different even with the same Magnitude. The 0:30 AM on September 20 looks terrifying on the seismograph, certainly if compared to other activity.
