WELLINGTON, New Zealand (AP) A series of strong
earthquakes struck the New Zealand city of Christchurch on
Friday, rattling buildings, sending goods tumbling from shelves
and prompting terrified holiday shoppers to flee into the
streets. There was no tsunami alert issued and the city appeared
to have been spared major damage.
The first 5.8-magnitude quake struck Friday afternoon, 16 miles
north of Christchurch and 2.5 miles deep, the U.S. Geological
Survey said. Minutes later, a 5.3-magnitude aftershock hit.
About an hour after that, the city was shaken by another
5.8-magnitude temblor, the U.S.G.S. said, though New Zealand's
geological agency GNS Science recorded that aftershock as a
magnitude-6.0. Both aftershocks were less than 3 miles deep.
