There has been more earthquake activity in Canterbury this morning and overnight with eight strong aftershocks continuing to rattle the region.

Aftershocks were felt today at around 3am and 7am and there were two in quick succession at around 10.20am. The first registered 3.9 and minutes later, at 10.25am, there was a 3.5 magnitude shake.

GNS duty seismologist Lara Bland says it follows four shakes which hit in a period of 40 minutes last night.

"They've been on the larger end of the scale" she told NewstalkZB, "they're being felt all around Christchurch because they're reasonably shallow"

Ms Bland says there have been around 290 aftershocks of magnitude 3.5 or more since the big one on September 4th.
