Would you have described it as a "massive" aftershock?
"GNS Science natural hazards manager Kelvin Berryman said the pattern of aftershocks was changing. Instead of being located around the tips of the recently revealed Greendale Fault, which runs from near Hororata to north of Rolleston, they were more widespread. Earthquake scientists were "watching very carefully" for any signs the underground part of the fault might be rupturing towards Christchurch. "We would be very concerned about that," he said. "What the aftershock sequence does suggest at this stage is there's been a big area of rock being stressed at the ends of the fault that we didn't know about, and strain is being readjusted around the region." Asked if the Greendale Fault extended underneath the city, Berryman said: "We can't rule it out but there's no particular positive evidence at the moment."
