6.3 magnitude earthquake part of aftershock sequence
February the 22nd's devastating magnitude 6.3 earthquake centred southeast of Christchurch was part of the aftershock sequence that has been occurring since the September magnitude 7.1 quake near Darfield, 40km west of the city, an earthquake geologist said today. (Read more in the press release).

The information below is about the event on the 4th of September 2010 popularly known as the "Darfield Earthquake".
In the early hours of Saturday morning on 4 September 2010, people in Christchurch and the surrounding Canterbury region were jolted awake by the most damaging earthquake in New Zealand since the deadly magnitude 7.8 Hawke's Bay (Napier) earthquake in 1931. There was one important difference-this time there has been no loss of life. Luck played a part-the quake occurred at a time when everyone was home in bed and the streets were largely deserted. However, the lack of casualties was mainly due to New Zealand's strict building codes, which aim to ensure that buildings do not become deathtraps in a major quake. Learn more about the shaking, liquefaction, aftershocks and how the fault was found - here.

Thanks for your help.
We have been overwhelmed with responses from people willing to house our miniature seismometers. We now have 200 of them installed in Christchurch homes collecting valuable information.
Thankyou. (More details here).
