Subsequent earthquakes hit on Sunday morning and Sunday evening with more than 200 aftershocks being felt every single day.
Experts have said that after a magnitude six quake, like the one felt on Sunday evening, up to 10 magnitude five quakes and as many as 100 magnitude four quakes could be expected.
The first quake hit last Friday at 9am, and measured 5.6 on the Richter scale. Two more large quakes followed on Sunday, the first measuring 5.5 and the later, evening quake 6.5 on the Richter scale.
The seismic activity though is expected to diminish now with the GNS Science seismology team putting the chance of a further quake measuring six or above at nine per cent now.
