An aftershock rattled buildings in the earthquake-ravaged city of Christchurch in New Zealand on Monday but there were no reports of serious damage or injuries.

The U.S. Geological Survey said the 5.0-magnitude quake struck 14 miles (22 kilometers) west of Christchurch at a depth of just under 2 miles (3 kilometers).

Christchurch has been rocked by scores of aftershocks since a devastating earthquake struck the city in February, killing 181 people. The February quake was New Zealand's most expensive natural disaster, costing an estimated $15 billion.

Monday's quake knocked items off store shelves, but officials say there have been no reports of serious damage or injuries.
