Several large earthquakes have hit Christchurch, New Zealand, on 23 December 2011, leaving 60 people injured.
The first earthquake to hit was of a 5.8 magnitude and seismic activity was reported at the airport as buildings swayed but no damage has occurred to the runways.
Shoppers and workers were also pretty badly shook up as produce fell from supermarket shelves. That quake was followed by a series of aftershocks, including one of 6 magnitude and two more of 5 magnitude or greater.
The Christchurch Central Business District red zone, that had been devastated by last February’s earthquake, which killed 182, had to be shut down.
According to GeoNet, which monitors seismic activity in New Zealand, the first 5.8 earthquake hit 20 kilometers north-east of Lyttelton just before 2 p.m. local time.
Less than 10 minutes later, another quake hit at 5.3 magnitude, some 20 kilometers east of Christchurch, and soon after a magnitude 4.2 followed.
Then over an hour later, a magnitude 6 quake rattled Christchurch, followed by another one of a 5 magnitude an hour after that and was shortly followed by a magnitude 4 quake!Local authorities are saying that today's cluster of quakes, only two days before Christmas, means that the area will be on alert for continued seismic activity.
