LATEST: Cantabrians have been shaken by a 4.7 magnitude quake this evening.
The tremor struck at 9.15pm, and was centred 15km west of Christchurch, at a depth of 10km.
The shake was the strongest aftershock experienced in the region since a 4.8 quake on July 6, 2012.
The quake caused a flurry of online traffic that overloaded Geonet's website, and many took to social media to comment.
A Twitter user said: "Well that one got me out of my chair. I think I'm out of practice."
