Canterbury is still being subjected to a flurry of seismic activity nearly a fortnight after the 7.1-magnitude earthquake struck, with a swarm of shallow aftershocks hitting the region overnight.

Nine aftershocks have struck since 9pm, with six hitting the region within a one-hour period from 10.28pm.

Two of the shallowest aftershocks struck at just 3km deep, with one felt in Christchurch at 11.23pm and another in Darfield at 12.08am.

The strongest shocks overnight were recorded at 4.4-magnitude, GNS Science reported.
