Shallow quake shakes Canterbury
A magnitude-3.8 earthquake rocked Canterbury this afternoon.
GeoNet said the quake struck at 4.44pm and was centred 10 kilometres southeast of Christchurch at a depth of 3km.
The tremor's intensity was described as "strong".
Almost 450 people have reported feeling the quake on GeoNet so far.
Hundreds of Canterbury residents took to the social media after the shake.
Twitter user Joy Reid tweeted: "Shelves shook in Pak 'n Save but nothing fell off. Car alarms now going off in car park."
Other Twitter users wrote of rushing to their doorframes and going under their desks.
The intensity of the quake varied across the city, according to people posting on the Trade Me message board.
One person in Woolston said the shake felt bigger than a 3.8.
This was echoed by people in Heathcote, Diamond Harbour, Bromley, Cashmere and Hoon Hay.
However, one Redwood resident said it felt like a "very gentle roll".
Police and the Fire Service said they had had no calls for assistance after the quake.
A Canterbury Earthquake Recovery Authority spokeswoman said there had been no reports of rockfalls.
