(CHRISTCHURCH, New Zealand) -- Two earthquakes rocked Christchurch, New Zealand Monday, nearly four months after a 6.3 magnitude tremor struck the city, killing close to 200 people and destroying tens of thousands of homes.
The first quake hit six miles from Christchurch and measured 4.6 on the Richter scale, according to the U.S. Geological Survey. A second, 6.0-magnitude tremor then struck eight miles from the city just over an hour later.
Shopping centers, office buildings and the city's airport were evacuated as a result of the quakes, the BBC said. No injuries have been reported.
Christchurch Mayor Bob Parker told the BBC that the tremors "caused a significant amount of damage in the central city area which has basically been closed to the public for some time."
He added that "The city has again lost water and power to a number of areas."
