Christchurch earthquake, 22 Feb 2011
Variable slip model 3.04SRL, 22 September 2011
Based on ground displacements from GPS and DInSAR (Cosmo-SkyMed and ALOS/PALSAR); elastic half-space assumption.
Two-fault solution.
Fault 1 is interpreted to be the main shock fault plane.
Fault 2 is interpreted to be associated with the Mw 5.8 and 5.9 aftershocks that occurred within 2 hours of the main shock.
Lat, lon and depth are to the centre of the fault patch.
Strike, dip and rake use the Aki & Richards convention.
