All aftershocks since Sept. 4 2010 (red are deep; star is Feb 21, 2011 event) http://www.christchurchquakemap.co.nz/week http://earthquake.usgs.gov/earthquakes/eqarchives/poster/2011/20110221.php http://www.geonet.org.nz http://www.geonet.org.nz Canterbury M7.2 earthquake Sept. 4 2010 M6.3 aftershock Feb. 21, 2011
Shaking intensity in the city was much greater for this earthquake than the magnitude 7.1 earthquake from last September, or any of the aftershocks. The highest shaking was recorded at Pages Road Pumping Station at 188 %g, with readings of 127 %g at Heathcote Valley Primary School and 107 %g at Hulverstone Road Pumping Station. This is due to the proximity of the epicentre to the city and the shallow depth. The earthquake has a reverse faulting mechanism. http://www.geonet.org.nz/news/feb-2011-christchurch-badly-damaged-by-magnitude-6-3-earthquake.html
