Earthquake devastates Christchurch

摘要

The 6.3-magnitude earthquake that struck Christchurch, New Zealand, on 22 February was probably part of a sequence of aftershocks that followed a 7.0-magnitude earthquake on 3 September 2010, according to the US Geological Survey. Although it was more powerful, September's quake caused no deaths. The aftershock was shallower, much closer to Christchurch, and struck at a busy hour, just before 1 p.m. local time; 65 deaths were confirmed as Nature went to press.
