UPDATE 27/12/2010 13:39 UTC : Surprisingly for many people, but the so called “aftershocks” have been labeled by members of the Earthquake Commission as a new earthquake (see link to article below), this mainly for “practical reasons”. Seismologically they are still labeled as “aftershocks”.

UPDATE 27/12/2010 13:28 UTC : Most of the central area in New Zealand South Island city of Christchurch were reopened to business on Monday after Sunday’s cluster of aftershocks caused part of the central business district to be cordoned off.

One moderate aftershock and a second weak  very shallow aftershock have scared a lot of people in Christchurch, New Zealand.
The first more powerful aftershock occurred Sunday morning at 10:30 AM local time. A lot of people were on the city streets when some minor damage scared them a lot as bricks and mortar crashed from buildings.
After the misery of the main shock with epicenter in Darfield in September 2010, this damaging aftershock right under Christchurch puts a huge burden on the Christmas and New Year’s festivities.
Sunday’s aftershocks were a setback for retailers for which Boxing Day sales were so important.

The danger living in this fragile area is on everybody’s mind again.
Police blocked a number of streets in the city center to avoid injuries of falling objects.

Since the magnitude 4.9 shake at 10.30am that caused some damage in the city, cut power and alarmed many residents, the ground has barely stopped shaking for more than a few minutes at a time.

The last 2 quakes were being felt so strongly because they were all close the center of the city and were being generated by rocks breaking in the first 5km below the surface.
