Darfield Earthquake, 09/03/2010, Mw7.0

Christchurch Earthquake, 02/21/2011, Mw6.1

Comparing Population Exposure Much greater exposures at high intensities for the Christchurch earthquake.

Christchurch Earthquake Population Exposure This Google Earth snap-shot shows the extent of earthquake ground shaking (from USGS ShakeMap; represented in color) overlain on population density (from LandScan 2008, Oakridge National Labs; represented as height of vertical bars) at a grid size of 1 km 2.

Comparing Shaking Distributions In Christchurch, accelerations were much higher during the 02/21 event - up to x6 the accelerations of the Darfield earthquake.

Comparing Shaking Distributions The concentration of higher accelerations coincided with the regions of highest population density. Population data from LandScan 2008, Oakridge National Labs.

Comparing Ground Motions The figures on the left compare preliminary ground motions for stations in the Christchurch region observing both the Christchurch and Darfield earthquakes. Figures courtesy of Brendon Bradley; data from GNS Science, New Zealand. HPSC PRPC

Darfield Earthquake Aftershock Sequence, M:Time History Christchurch EQ Darfield EQ

Darfield Earthquake Aftershock Sequence, Spatial Energy Release Understanding the precise relationship between the two events involves unraveling the complex faulting history of the Darfield earthquake, and how that network of faults relates to the fault that ruptured on 02/21. This image projects the energy release of all earthquakes in the sequence onto an E-W profile.
