Causative faults (source areas) and magnitudes of the 2010-2011 Christchurch earthquakes (4 SEP 2010 EQ: red line = trace First of all, tension builds up between tectonic plates as they collide or move past, or away from each other, these plates are driven by convection currents in the semi-molten layer below the crust. This is largely due to the earthquake taking place in the early hours of the morning when residents were in bed, and due to the distance of the earthquake from major urban areas.
