More than three months since the deadly February 22 Earthquakes that killed almost 200 people in Christchurch and exactly one week since the Queen's Birthday Aftershock, another series of significant quakes hit the Canterbury region today. The biggest so far was magnitude 6.3 at 02:20 PM (New Zealand Time) with preceding foreshock a strong magnitude 5.7.

According to the Christchurch Quake Map website, 7366 quakes hit the region since September 4, 2010 (more to come) and the Greendale Faultline near Rolleston is somewhat getting closer to the city. Some buildings that survived the September 4 Earthquakes, the Boxing Day Quakes, and the February 22 Earthquakes also collapsed because of today's quakes.
The numbers of quakes since September last year suggested that what happened in Canterbury is an example of (or closest thing to) an “Earthquakes Swarm”, where a local area experiences sequences of many earthquakes striking in a certain period of time.
Hope everyone are OK and God Bless!
