Shaken New Zealand

On Tuesday, an earthquake hit one of New Zealand's largest cities, Christchurch, destroying buildings and killing at least 65 people. Our January 10 issue included a story on the one-year anniversary of Haiti's devastating 7.0-magnitude earthquake. In that story, we explained that scientists use a magnitude scale to measure an earthquake's power. Each 1-point increase on the scale represents an increase of 10 times in the quake's size (as measured on a seismogram). The earthquake in New Zealand was 1,000 times bigger than an earthquake measuring 3.3. What was the magnitude of the New Zealand earthquake?

The New Zealand earthquake had a magnitude of 6.3.
